What
is Avian Flu?
Avian flu (also "bird flu", "avian
influenza", "bird influenza"), means "flu
from viruses adapted to birds", but is
sometimes mistakenly used to refer to both
other flu subsets (such as H5N1 flu) or the
viruses that cause them (such as H5N1)
Simply
Bird flu is an infection caused by avian
(bird) influenza (flu) viruses.
Bird
flu symptoms in humans
Include: fever, cough, sore throat, and
muscle aches, to eye infections, pneumonia,
and ARDS.
Transmission
Birds that are infected with avian influenza
viruses can shed virus in saliva, nasal
secretions, and feces. Contact with feces or
respiratory secretions are important in the
transmission of infection among poultry.
Between flocks, infection usually spreads
due to movement of infected birds and the
actions of humans in moving feedstuff,
personnel, equipment, and vehicles into and
from premises that are contaminated with
infected feces or respiratory secretions.
The duration that these viruses can survive
in the environment depends on temperature
and humidity conditions, but they may
survive up to weeks in cooler and moister
conditions.
It is believed that most cases of avian
influenza infection in humans have resulted
from contact with infected poultry or
contaminated surfaces. However, other means
of transmission are also possible, such as
the virus becoming aerosolized and landing
on exposed surfaces of the mouth, nose, or
eyes, or being inhaled into the lungs
Prevention and Control
of Influenza
1- Personal
Protective Equipment |
| |
|
|
•
|
Disposable gloves made of
lightweight nitrile or vinyl or
heavy duty rubber work gloves that
can be disinfected should be worn.
To protect against dermatitis, which
can occur from prolonged exposure of
the skin to moisture in gloves
caused by perspiration, a thin
cotton glove can be worn inside the
external glove. Gloves should be
changed if torn or otherwise
damaged. Remove gloves promptly
after use, before touching
non-contaminated items and
environmental surfaces. |
| |
|
|
• |
Protective clothing, preferably
disposable outer garments or
coveralls, an impermeable apron or
surgical gowns with long cuffed
sleeves, plus an impermeable apron
should be worn. |
| |
|
|
• |
Disposable protective shoe covers or
rubber or polyurethane boots that
can be cleaned and disinfected
should be worn. |
| |
|
|
• |
Safety goggles should be worn to
protect the mucous membranes of
eyes. |
| |
|
|
• |
Disposable particulate respirators
(e.g., N-95, N-99, or N-100) are the
minimum level of respiratory
protection that should be worn. This
level or higher respiratory
protection may already be in use in
poultry operations due to other
hazards that exist in the
environment (e.g., other vapors and
dusts). Workers must be fit-tested
to the respirator model that they
will wear and also know how to check
the face-piece to face seal. Workers
who cannot wear a disposable
particulate respirator because of
facial hair or other fit limitations
should wear a loose-fitting (i.e.,
helmeted or hooded) powered air
purifying respirator equipped with
high-efficiency filters.

Disposable PPE should be properly
discarded, and non-disposable PPE
should be cleaned and disinfected as
specified in state government,
industry, or USDA outbreak-response
guidelines. Hand hygiene measures
should be performed after removal of
PPE. |
2- Vaccination with
Seasonal Influenza Vaccine
3- Administration of Antiviral Drugs for
Prophylaxis
4- Surveillance and Monitoring of Workers in
poultry field
