The following information is provided to
assist fire fighters and emergency medical personnel to prepare for a potential
Influenza Pandemic and to advise all first responders with potential Influenza
exposure to use proper infection control precautions to protect their own health
and that of the public. Regardless of an influenza pandemic event, all
first responders should receive influenza vaccine each year to protect
themselves, their families and the public they serve from the annual influenza
outbreak.
An Influenza Pandemic could potentially
result in widespread illness and deaths around the world. Because all
disasters and emergencies are dealt with locally, each local fire and emergency
medical department must collaborate with its local government, public health
department, and community stakeholders to devise a plan of action. A
lesson learned from the recent Katrina/Rita disasters is that preparation for
emergencies requires advanced planning if the response is to be effective and
efficient.

Influenza (the “flu”) is a seasonal
respiratory illness caused by a virus and is characterized by fever, chills,
sore throat, nasal congestion, cough, exhaustion, and severe muscle aches.
The flu season typically starts in late November and lasts through early spring.
It affects about 30-50 million Americans each year. The flu differs from
the common cold in that it lasts longer (about two weeks) and can be temporarily
debilitating even in healthy individuals. There are three types of
Influenza viruses – A, B, and C. Influenza A is further categorized
into subtypes based on the type of two surface proteins – hemagglutinin (H) and
neuraminidase (N).

While types A and B cause an outbreak in
most years (seasonal flu), type C causes mild to no disease. Minor genetic
changes called antigenic drift may give rise to new Influenza A
subtypes and Influenza B viruses. The circulation of these viruses causes an
outbreak each year, and thus the need for a new flu vaccine each year.
After an infection with an influenza virus or inoculation with an influenza
vaccine, the body develops immunity to that specific type of influenza virus.
However, due to the viral ability to mutate, new vaccines for potential new
types of viruses must be developed and given each year to those most susceptible
for infection (i.e. first responders, healthcare workers, the elderly, etc).
Influenza A can also undergo a major genetic
change called antigenic shift resulting in a novel influenza A
with a new H or H+N protein combination for which there is little or no immunity
among the majority of people. If this new strain of Influenza A easily
spreads from person to person and causes serious illness, then a pandemic is
likely to occur.
Pandemic refers to the global
spread of a disease, while an epidemic is localized to a
geographic region. An influenza pandemic occurs when there is a worldwide
spread of a new strain of influenza A virus that causes serious illness and is
easily spread from person to person. Pandemic flu has the potential to
kill people regardless of age or health status.
One way for a new pandemic flu strain to
arise is through the mixing of different types of influenza A viruses. For
instance, the influenza viruses that caused the Asian Flu and the Hong Kong Flu
Pandemics are believed to have come from the mixing of human influenza and avian
(bird) influenza viruses in another animal such as a pig. The new strain
was then able to cause a much more severe illness in humans. The Spanish
Flu Pandemic on the other hand is thought to have started from an avian flu that
directly infected humans, and the mixing of the avian influenza with the human
influenza within a human led to the new deadly strain of influenza A virus.
During the 20th Century, new
strains of Influenza A viruses have resulted in three influenza pandemics:
- Spanish Flu (1918-1919) –
Influenza H1N1 caused an estimated 50 million deaths worldwide and 500,000
deaths in U.S. alone. Healthy people, as well as those in frail
condition, were equally affected, and many died within the first few days
after infection.
- Asian Flu (1957-58) –Influenza
H2N2 started in China in February 1957, by June 1957 it spread to U.S. and
caused 70,000 deaths in U.S.
- Hong Kong Flu (1968-1969) –
Influenza H3N2 started in Hong Kong in early 1968. Later in the
year, it spread to the U.S. and caused 34,000 deaths.
The U.S. Centers for Disease Control and
Prevention (CDC), the Public Health Agency of Canada (PHAC) and the World Health
Organization (WHO) have a large surveillance system for detecting possible
pandemic flu stains around the world.
The most common method for diagnosing
influenza is the Rapid Flu Test. Depending on the type of test
used, it can identify influenza A and/or B.
Proper sample collection is critical for
testing. Because the tests rely on detecting the virus being shed in the
respiratory secretions of the infected person, the test must be done during the
first few days of illness when there is viral shedding. The best sample is
a nasal aspirate, but nasopharyngeal swabs are most frequently used. With
the patient's head tilted back, a dacron swab (like a very long Q-tip) is
inserted into a nostril until there’s resistance (~1-2 inches in) and then
rotated several times.
The major advantages of the Rapid Flu Test
are that it can be done in an outpatient setting and the results return within
30 min to 2 hours. The major disadvantages are that true influenza cases
will be missed up to 30% of the time (false negative result) and some people
without influenza will be misdiagnosed as having influenza (false positive
result).
The gold standard for diagnosing influenza
is a viral culture. The virus from the nasal secretion is grown and
identified in the laboratory. The advantage of a viral culture
is that the specific viral strain and type can be identified. Such
detailed information would be critical in detecting influenza outbreaks
(including surveillance for the pandemic strain) and for developing vaccines.
The major disadvantages are that the results take about 3 to 10 days and not all
labs are equipped to perform a viral culture.
Influenza is spread from person to person by
contact with respiratory secretions from an infected person. When an
infected person coughs or sneezes, the viruses are carried in large droplets
which settle on the surfaces of the upper respiratory tracts of persons who are
nearby (i.e. within 3 feet of the infected person). The viruses can also
spread by direct or indirect contact with respiratory secretions – touching
contaminated surfaces and then touching the eyes, nose or mouth.
Influenza is more infectious than SARS.
Infected adults can spread the virus from the day before exhibiting symptoms to
5 days after symptoms start (2 days on average); whereas, the transmission
timeline for SARS is 6 to 8 days. Infected children can spread the virus
for 10 days or longer. Due to the highly contagious nature of
influenza virus, first responders who may be exposed to or are taking care of
persons suspected of influenza should wear appropriate protection (discussed
later in this article).
Treatment. Four antiviral
medications are approved by the U.S. Food and Drug Administration (FDA) for
treatment and or prevention of influenza – Tamiflu (oseltamivir), Relenza
(zanamivir), Symmetrel (amantadine), and Flumadine (rimantadine).
While antivirals taken at the onset of the illness may decrease the severity and
duration of the illness, there is no definitive treatment for influenza.
If antiviral treatment is given within 48 hours, it may reduce the severity of
symptoms and the duration of illness. Treatment of infected persons does
not prevent further spread of infection, but it may reduce the viral shedding
and thus the degree of contagion.
The antivirals do not help if given beyond
48 hours of onset and they will not work against other viruses or against
bacterial infections that may occur as a complication of influenza.
A patient may develop resistance to one or
all antivirals. The bird flu (Influenza A H5N1) identified in humans in
Asia in 2004 to 2005 is already resistant to amantadine and rimantadine, and
higher doses of oseltamivir must be given for a longer period to be effective.
Observational studies indicate that early intervention and an extended regime of
oseltamivir may help increase the chance of survival, but results are
inconclusive due to limited data.
Prevention. An effective
vaccine could potentially thwart an epidemic before it becomes a pandemic. However, once the potential pandemic strain is
identified, it takes several months for the vaccine to be developed and mass
produced for wide distribution. A vaccine prototype has been developed
against Avian Flu H5N1, but there is no guarantee that it would be effective
against the mutated pandemic strain.
While the timing of the next pandemic is
uncertain, fire fighters must continue to practice preventive measures such as
respiratory hygiene, cough etiquette, and annual flu vaccination. As with
all biologic hazards, universal precautions should be practiced.
Influenza epidemics result in about 35,000
deaths each year in the U.S. Contributing to the high death rate is the
inadequate level of vaccination among health care workers who unknowingly
transmit the virus to persons susceptible for a serious illness from influenza.
Data from several studies indicate that vaccination of health care workers
significantly reduces the influenza death rate among the patients for whom they
provide care.

In preparation for any emergency,
organizations should follow the principals of emergency preparedness. These
principles include:
- A pre-tested Plan of Action that is
developed in advance of the emergency event.
-
Defined roles and responsibilities for key organizations and individuals who
will be involved in the emergency response.
-
Routine communication among key organizations and individuals established as
part of the planning process.
- Identification of resources, including
financial.
- Dissemination of educational materials to
all first responders.
As with any
preparation for an emergency, all organizations should plan for the Pandemic
Flu. To assist state, provincial and local governments in the planning
process, the CDC has developed a checklist which can be found at
http://www.pandemicflu.gov/plan/statelocalchecklist.html. A planning checklist was also
released for use by medical, dental, podiatric, and chiropractic offices,
ambulatory surgery centers, hemodialysis centers and outpatient clinics, which
can be found at
http://www.pandemicflu.gov/plan/medical.html. Also, the IAFF has
developed a checklist specific to the fire service which is based on NFPA 1500
Standard on Fire Department Occupational Safety and Health Program; NFPA
1581 Standard on Fire Department Infection Control Program; and NFPA 1600
Standard on Disaster / Emergency Management and Business Continuity Programs
which can be found at
../PDF/IAFF
Influenza Pandemic Checklist.pdf.
In addition to simulation exercises,
computer models can be utilized to assist in estimating the impact of a Pandemic
Flu. To this end, CDC has developed FluAid, software to assist state,
provincial and local planners:
http://www2.cdc.gov/od/fluaid/default.htm.
The World Health Organization also has
been developing a
pandemic influenza draft protocol for rapid response and
containment. Their first report was issued on January 27, 2006 and can be
found for review and download at:
http://www.who.int/csr/disease/avian_influenza/updates/en/index.html.
The WHO expects this project to be completed by May 2006.
The U.S.
Department of Health and Human Services (HHS) has issued an updated report in
March 2006 that outlines how that U.S. federal funding is being used to help
achieve HHS’s five primary objectives.
-
Monitoring disease spread to support rapid response.
-
Developing vaccines and vaccine production capacity.
-
Stockpiling antivirals and other countermeasures.
-
Coordinating federal, state and local preparation.
-
Enhancing outreach and communications planning.

The Avian Flu H5N1 (or Bird Flu) is a strain
of Avian influenza, a virus that primarily infects birds. On rare
occasions, avian influenza can infect another species such as humans. When
a person is infected with both the Avian and Human influenzas at the same time,
there is a risk of genetic exchange between the two influenza viruses and the
rise of a deadly viral strain that can easily spread from human to human.
The Avian Flu H5N1 is NOT the same as the
seasonal flu for which you get the annual flu vaccine nor is it a pandemic flu.
The current fears concerning the new Avian Flu H5N1 are based on it's spreading
through birds across Asia and parts of Europe and it’s ability to infect and
cause serious harm to humans as demonstrated in 1997 in Hong Kong and 2003 in
Southeast Asia. Of the 120 persons infected in Southeast Asia, more than
60 have died. Also, the deadly Spanish Flu of 1918 is now thought to have
originated from an avian flu and the pattern of spread of the current Avian Flu
is reminiscent of the Spanish Flu, which came in successive waves. The
first wave came in the spring and summer of 1918 and caused a widespread disease
but few deaths. Then a second wave in the following fall and winter spread
quickly and killed millions of people around the world. Like the Spanish
Flu, if the current Avian Flu develops the ability to easily spread from
person-to-person, then it will become a serious public health threat (i.e. a
pandemic).
No one can predict when the next pandemic
will occur. But when it does, according to the WHO, CDC and PHAC, it will
have the potential to cause more deaths and illness than any other previous
public health threat.
As of March 13, 2006, a total of 152
confirmed cases and 83 deaths have been reported from 6 countries. The
following chart presents the cumulative number of confirmed cases of Avian Flu
reported to the World Health Organization.

Interpandemic Period
- Phase 1: No new influenza
subtypes detected in humans, but may be present in animals. Risk of
human infection is low.
- Phase 2: No new influenza
subtypes detected in humans, but a circulating animal influenza subtype
poses a risk of human disease.
Pandemic Alert Period
- Phase 3: New influenza
subtypes infecting humans but minimal to no human-to-human spread.
- Phase 4: Small clusters of
limited human-to-human spread (i.e. the virus is not well adapted to
humans).
- Phase 5: Larger clusters of
geographically localized human-to-human spread (i.e. the virus is adapting
to humans but still not easily spread from person to person).
Pandemic Period
- Phase 6: Increased and
sustained spread of virus in the general population.
The current media coverage on the Bird Flu
is likely to continue. Real time mass media, such as the radio or
television, will likely be your best source for an impending pandemic. As
of January 25, 2006, CDC has declared the United States to be in Pandemic Alert
Phase 3.

How Avian
Flu H5N1 presents?
- Best case scenario: signs and symptoms
will be similar but more severe than the seasonal influenza with near
complete resolution in few weeks.
- Characteristic Signs and Symptoms:
- Persistent fever
- Lymphopenia (low white blood cell
count)
- Other Signs and Symptoms:
- chills
- productive or dry cough
- shortness of breath
- fatigue
- muscle aches
- Complication: Progression to
pneumonia or Acute Respiratory Distress Syndrome (ARDS) within 5 to 7 days.
-
Case fatality: Over 50% (i.e. more than half of all persons infected with
Avian Flu H5N1 have died).
- Exposure to sick poultry – e.g. touched
sick or dead poultry with bare hands.
-
Exposure to affected areas (SE Asia or Eastern Europe) or persons
from these areas.
[to top]
The best protection against an Avian Flu
H5N1 outbreak in North America is strict adherence to infection control
procedures. Follow universal precautions and the latest updates issued by the
CDC, PHAC and WHO.
Additionally, fire departments should have
an Infection Control program that meets the minimum requirements of NFPA 1581 (chapters 5 and 6), Standard on Fire Department
Infection Control Program (http://www.nfpa.org).
Because the exact nature of the pandemic flu
is unknown, the best preparation for now is to be aware of the guidelines for
handling highly contagious respiratory infectious agents. Following are
the guidelines adopted in part from documents developed by the IAFF from both
Smallpox and SARS preparation and experience.
Only use a P-100 disposable respirator
as a minimum
respiratory protection or a respirator with a higher level of respiratory
protection, including a full or half facepiece air purifying respirator
(APR) or powered air purifying respirator (PAPR) with a HEPA filter/canister
.
When
properly fitted, maintained and used, a P-100 respirator (or an APR or PAPR
with a HEPA filter) provides protection from inhalation of infectious
airborne droplets.
The P-100 respirator
provides the highest levels of aerosol protection as compared to respirators
rated only for particulate (aerosol) protection.
However, there are NO safe exposure levels (i.e. the amount you can inhale
without adverse health effects) for biological aerosols. Respirators can reduce inhalation exposures but cannot eliminate the
risk of contracting infection or developing illness or disease.
Additionally, the type of respirator facepiece and filter class required
varies depending upon one's activities and risk of exposure. For public and
hospital use, many have suggested that N-95 respirators. The IAFF does not
believe that this type of respirator will afford fire fighter and emergency
medical personnel proper protection. Accordingly, the IAFF recommends that
emergency responders use, at a minimum, a P-100 respirator.
The IAFF’s
P-100 filter efficiency recommendation is consistent with NIOSH recommendations
for emergency response to biological agent incidents.
http://www.cdc.gov/niosh/unp-intrecppe.htm. Additionally the IAFF
recommendation is consistent with federal OSHA regulations that state “where
workers are exposed to a hazard that would require the use of a respirator with
HEPA filtration, the appropriate class of respirator under the
42 CFR Part 84 certification is the Type 100 (N-100,
R-100, or P-100).”
The IAFF recommendation is
also consistent with the specifications contained in the World Health
Organization’s Hospital Infection Control Guidance for SARS (http://www.who.int/csr/sars/infectioncontrol/en).
Additionally, disposable respirators must
have seal enhancing elastomeric components (e.g. rubber or plastic respirator to
face seals) and must be equipped with two or more adjustable suspension straps.
The IAFF believes, and research has demonstrated, that without these components
it is difficult to obtain and maintain a seal in the workplace.
All disposable respirators, as well as APRs
and PAPRs, must also be certified by the National Institute for Occupational
Safety and Health (NIOSH). NIOSH-approved disposable respirators are
marked with the manufacturer’s name, the part number (P/N), the level of
protection provided by the filter (e.g., P-100), and “NIOSH.” This information
is printed on the facepiece, exhalation valve cover, or head straps. If a
NIOSH marking is not on the respirator, it is not certified by NIOSH and should
not be used.
An P-100
respirator is one of nine types of disposable particulate respirators.
Particulate respirators are also known as “air-purifying respirators” because
they protect by filtering particles out of the air as you breathe. These
respirators protect
only against particles—not gases or vapors.
Since airborne
biological agents such as bacteria or viruses are particles, they can be
filtered by particulate respirators.
Respirators that filter out
at least 95% of airborne particles during “worse case” testing using a
“most-penetrating” sized particle are given a "95" rating. Those that filter out
at least 99% receive a “99” rating. And those that filter at least 99.97%
(essentially 100%) receive a “100” rating.
Respirators in this family are rated as N,
R, or P for protection against oils. This rating is important because some
industrial oils can degrade the filter performance so it does not filter
properly.* Respirators are rated “N,” if they are not resistant to oil, “R”
if somewhat resistant to oil, and “P”
if strongly resistant (oil
proof) or if
conditions unknown. The IAFF basis it's recommendation for "P" rated
disposable due to the fact that emergency response is usually to "unknown
condition" environments. Currently there are no NIOSH approved R-99, P-99
or R-100 disposable particulate respirators.
Since respirator classes are designated
for use in certain environments with the P-100 being the most universal, NIOSH
has designated only the P-100 respirator with magenta color coding and markings.
A list of manufacturers/suppliers and model
numbers of P-100 disposable respirators is maintained by NIOSH at
http://www.cdc.gov/niosh/npptl/topics/respirators/disp_part/p100list1.html.
The effectiveness of any
respirator is highly dependent on having respirators that are well-fitted to
fire fighters' faces. Respirators that leak may offer essentially no
respiratory protection. All respirator use must be administered as part of a
comprehensive Respiratory Protection Program (RPP), according to the
Occupational Safety and Health Administration (OSHA). The RPP contains
provisions for training respirator users, selecting and maintaining respirator
equipment, conducting fit-checks and conducting fit tests. For additional
information, see the Respiratory Protection Standard (29CFR 1910.134), under the
Laws and Regulations link at
http://www.osha.gov.
A respirator is not a guarantee of
protection against any disease. However, if a high-filtration respirator is worn
with eye protection and medical gloves by a trained individual, a high degree of
protection should be conferred.

P-100 Respirator
In the
event that an influenza pandemic occurs, the availability of disposable
respirators may be severely strained and demand may far exceed current
manufacturer production capability. The U.S. Department of Heath and Human
Services (DHHS) has charged the
Institute of Medicine (IOM) of
the National
Academies (which provides science-based advice on matters of biomedical
science, medicine, and health)
with making recommendations on the development of reusable respirators for use
during an Influenza pandemic in healthcare settings and for the general public.
The IAFF is participating in this process to ensure protection is not
compromised and will continue to push for the highest level of protection for
first responders. The IOM recommendations are due in the next couple of
months. Fire and EMS departments must assess their supply of disposable
respirators and determine whether there is a need to stockpile adequate supply
before the demand becomes overwhelming for the current production system.
For more information on the IOM project, click on the link below
http://www.iom.edu/CMS/3740/32033.aspx
Hand Care
Remember, one of the easiest ways to
transmit a viral infection from one person to another is through a hand-shake,
which transfers virus from the hand of one person who may have rubbed his nose
to another person's hand. The second individual then touches his/her nose, eyes,
or mouth and later develops an infection. In situations where the patient has a
high fever and any respiratory signs, take the following precautions:
- Don disposable medical gloves, certified
to NFPA 1999, Standard on Protective Clothing for Emergency Medical
Operations, prior to making any patient contact.
- Use of such disposable gloves should be
considered for any direct contact with body fluids of an infected patient.
However, these gloves are not intended to replace proper hand hygiene.
Immediately after activities involving contact with body fluids, gloves
should be removed and discarded and hands should be cleaned. Gloves must
never be washed or reused.
- The use of gloves does not eliminate
the need for hand hygiene. Likewise, the use of hand hygiene does not
eliminate the need for gloves. Gloves reduce hand contamination by 70
percent to 80 percent, prevent cross-contamination and protect both patients
and health care personnel from infection. Antiseptic handrubs should be used
before and after each patient, just as gloves should be changed before and
after each new patient. When soap and water become available,
thoroughly wash hands. Avoid touching hands to face until such a
thorough washing of hands takes place.
- When using an alcohol-based handrub,
apply the product to the palm of one hand and rub your hands together,
covering all surfaces of your hands and fingers, until your hands are dry.
Note the volume needed to reduce the number of bacteria on hands varies by
product.
- Personnel should avoid wearing artificial
nails and should keep natural nails less than one quarter of an inch long,
particularly if they come in contact with patients at high risk of acquiring
infections.
In situations where the patient has a high
fever or any respiratory illness symptoms, take the following precautions:
- Don protective eyewear, certified to NFPA
1999, Standard on Protective Clothing for Emergency Medical Operations,
in situations where bodily fluids may be splashed. Splash-protective eyewear
must be worn within 6 feet of the patient. Corrective eyeglasses alone are
not appropriate protection.
- Do not rub eyes before or after using
eyewear or after handling patients or equipment.
In situations where the patient has a high
fever or any respiratory illness symptoms, take the following precautions:
- Apply a disposable surgical mask (or
disposable respirator without an exhalation valve if surgical mask is not
available) to all persons suspected of having an infection (except for those
receiving oxygen therapy through a facemask).
- Each patient with suspected infection
should be advised to cover his or her mouth and nose with a facial tissue
when coughing or sneezing. If possible, a patient should wear a surgical
mask during close contact with uninfected persons to prevent spread of
infectious droplets. When an infected patient is unable to wear a surgical
mask, household members should wear surgical masks when in close contact
with the patient.
- When a patient requires rescue breathing,
use a bag-valve-mask -- NEVER use direct mouth-to-mouth or mouth-to-mask
resuscitation.
- When transporting persons suspected of
having a highly contagious respiratory infection, do not allow air to
recirculate within the vehicle, especially do not use the recirculation
(Maximum Level) control on the vehicle's heating/air conditioning system.
When possible, open windows/vents for improved ventilation.
- Respirators may not be removed to eat or
drink while in the transport vehicle. Personal activities that require
removal of respirators should not be performed in the patient-care cabin.
- The patient may wear a paper surgical
mask to reduce droplet production, if one can be tolerated.
- Oxygen delivery with simple and
non-rebreather facemasks may be used for patient oxygen support during
transport.
- A full facepiece APR or PAPR with a HEPA
filter or a P-100 respirator with goggles (or face-shields) must be worn for
all patient care within 6 feet of the patient. Corrective eyeglasses alone
are not appropriate protection.
- Patient care personnel should not wear
leather or other non-medical gloves while transporting patients.
- Eating, drinking, application of
cosmetics, and handling of contact lenses should not be done in the
immediate patient care area.
- Handling or storage of medication or
clinical specimens should not be done in areas where food or beverages are
stored or prepared.
- Dispose of disposable respirator,
respirator filters, gloves and other disposable equipment/supplies used at
the scene as bio-hazardous waste.
- Non-disposable respirators shall be
cleaned and disinfected in accordance with manufacture’s recommendation.
- For decontamination of non-disposable
equipment, follow manufacturer and departmental standard operating
procedures.
- If the turnout gear is visibly
contaminated by bodily fluid, it should be placed in a biohazard bag at the
scene and washed following prescribed laundry procedures. Chlorinated beach
shall not be used with any fire fighter protective clothing.
- Vehicles used to transport persons
suspected of having Avian Flu should be cleaned with a disinfectant cleanser
by staff wearing protective equipment, using a disinfectant cleanser.
- When possible, in advance of a patient
evaluation, healthcare providers should be informed that the individual is a
close contact of a Avian Flu patient. Patients presenting to health care
facilities who require assessment for Avian Flu should be diverted to a room
designated for respiratory isolation.
- Sharing of eating utensils, towels, and
bedding between Avian Flu patients and others should be avoided, although
these items can be used by others after routine cleaning (e.g., washing with
soap and hot water). Environmental surfaces soiled by body fluids should be
cleaned with a household disinfectant according to manufacturer’s
instructions; gloves should be worn during this activity.
- Household members or other close contacts
of Avian Flu patients who develop fever or respiratory symptoms should seek
healthcare evaluation.
- At this time, in the absence of fever or
respiratory symptoms, household members or other close contacts of Avian Flu
patients need not limit their activities outside the home. Within an
affected household, facial tissues and other waste from Avian Flu patients
may be discarded as normal household waste.

As of March 15,
2006, neither the CDC nor PHAC are advising
against travel to any of the countries with cases of Avian Flu. However,
the situation can change at any moment, so check the CDC alert site at
http://www.cdc.gov/travel/diseases.htm or the PHAC alert site at
http://www.phac-aspc.gc.ca/tmp-pmv/2006/h5n1060112_e.html prior to any
travel.
As of March 15, 2006, Avian Influenza H5N1
is not among the list of quarantinable communicable diseases under the U.S.
Public Health Service Act. As the risk for pandemic flu rises, the list will
likely be updated. The most recent U.S. Executive Order on quarantinable
diseases can be found at:
http://www.cdc.gov/ncidod/sars/executiveorder040403.htm. PHAC has not issued any quarantine information under its
Quarantine and Migration Health Program (QMHP) which is responsible for
implementing the
Canadian Quarantine Act and Regulations. Additional information on the
QMHP can be found at:
http://www.phac-aspc.gc.ca/cepr-cmiu/ophs-bssp/quar_e.html.
Many levels of government (Federal,
Provincial, State, and Local) have basic authority to compel isolation of sick
persons to protect the public. In the event that it is necessary to compel
isolation of a sick passenger, CDC and
PHAC will work with appropriate State, Provincial
and local officials to ensure that the passenger does not infect others.
There is no Pandemic Flu at the moment and
no case of Avian Flu H5N1 has been detected in North America. Health
authorities around the world are watching closely so that they may respond
promptly in the identification and reporting of suspect cases. The World Health Organization (WHO) will
issue a Global Alert should the need arise.

A
acute: Sudden onset, short course. May also
refer to intensity or severity.
aerosolized respiratory secretions: Liquid droplets,
suspended in air, that arise from coughing or sneezing. Aerosolized respiratory
secretions are responsible for the transmission of tuberculosis, and are one of
the major modes of influenza transmission.
Amantadine (Symmetrel): Antiviral medication for
treatment and prophylaxis of adults and children >1 year old with influenza type
A virus exposure. It is not effective against influenza type B.
antibodies: Proteins produced by the immune system
that act against an infecting agent.
antigen: Any substance that elicits an response from
the body's immune system, such as release of antibodies.
Antigenic
drift: Gradual minor change (mutation) in the genetic makeup of influenza
A and B strains that result in changes in the hemagglutinin (H) or neuraminidase
(N) proteins found on the viral surface. The ongoing changes of H and N
are the causes of annual epidemics and need for new influenza vaccine each year.
Antigenic
shift: A reassortment of influenza A genes resulting in a major change in
the H and N proteins. Because very few people are immunized against such a
novel strain of virus, antigenic shift may be associated with a pandemic.
Avian
Flu: A group of influenza viruses that primarily infect birds, but on
rare occasion may infect other animals such as pigs or humans.
C
CDC
(Centers for Disease Control and Prevention): A United States government
agency that seeks to promote health and quality of life by preventing and
controlling disease, injury, and disability.
E
Epidemic: An outbreak that spreads widely and affects
many persons within a region or population within a defined time period.
F
flu: Infection and illness due to influenza virus.
It is often erroneously used to refer to common colds or even gastrointestinal
illnesses.
H
Hemagglutinin (H): An agglutinating protein (antigen)
on the surface of influenza virus. Differences in the amino acid sequences
give rise to the different subtypes of influenza type A viruses.
hypoxia: A deficiency of oxygen reaching the tissues
of the body.
I
incubation period: The period of time between the
infection of an individual by a disease-causing agent and the manifestation of
the disease it causes.
infectious: Capable of transmitting an infectious
agent from one person to another
influenza: A highly contagious seasonal respiratory
illness caused by the influenza virus. It is characterized by fever,
chills, sore throat, nasal congestion, cough, exhaustion, and severe muscle
aches.
intubation: The introduction of a tube into the
trachea to mechanically maintain oxygen flow to the lungs.
M
morbidity: Departure from a state of well-being
(physiologically or psychologically).
mortality: Death
mutation: A relatively permanent change in the
genetic material
N
Neuraminidase (N): A hydrolytic enzyme (antigen) on
the surface of influenza virus. It dissolves the protective viscosity of
cellular mucous lining, allowing release of new viruses into the respiratory
tract.
NFPA (National Fire Protection Association):
An international nonprofit organization that seeks to reduce the worldwide
burden of fire and other hazards on the quality of life by providing and
advocating scientifically-based consensus codes and standards, research,
training, and education.
P
pandemic: Widely spread epidemic. Usually
refers to the global spread of disease.
prevention: Taking measures for anticipation,
prevention, detection, and early treatment of disease
Preventive Medicine: A branch of medical science
dealing with methods of preventing the occurrence of disease or illness
Public
Health: The art and science of protecting and improving community health
by means of prevention, education, disease control, and sanitation.
PHAC (Public Health Agency of
Canada): A Canadian government agency that seeks to promote
and protect the health of Canadians through leadership, partnership, innovation
and action in public health.
Q
quarantine: A restraint on the activities of persons
or the transport of goods that is designed to prevent the spread of disease.
R
resistance: The ability of microbial strains or
pathogens to withstand effects of antimicrobial agents
rimantadine (Flumadine): Antiviral medication for
treatment and prophylaxis of adults with influenza type A virus exposure.
It is not effective against influenza type B.
S
subtype: A sub-classification of influenza type A
viruses based on the surface proteins – hemagglutinin (H) and neuraminidase (N)
V
vaccination: The administration of vaccine in order
to induce an immune response for future protection against the infectious agent
of interest
vaccine: A substance that can stimulate the immune
system to protect against an infectious organism of interest at a future point
in time.
virus: A group of infectious parasites that are
typically much smaller than bacteria and characterized by their inability to
reproduce outside of a living host cell.
W
WHO
(World Health Organization): Specialized health agency of the United
Nations that seeks the attainment by all peoples of the highest possible level
of health. WHO is governed by 192 Member States through the World Health
Assembly.
