ETIOLOGY
Classification of the causative
agent
Virus family Orthomyxoviridae,
genus Influenzavirus A, B. To
date, all highly pathogenic
isolates have been influenza A
viruses of subtypes H5 and H7
HOST

Highly pathogenic avian
influenza isolates have been
obtained primarily from chickens
and turkeys
 It
is reasonable to assume all
avian species are susceptible to
infection
TRANSMISSION

Direct contact with secretions from infected
birds, excretion especially feces

Contaminated feed, water, equipment and
clothing

Clinically normal waterfowl and sea birds may
introduce the virus into flocks

Broken contaminated eggs may infect chicks in
the incubator
SOURCES OF VIRUS

Feces, respiratory secretions
 Highly
pathogenic viruses may remain
viable for long period of time in infected
feces, tissues and water

Bird flu, which has killed at least 13 people
in Vietnam, is largely transmitted through
bird droppings and uncooked meat, the
World Health Organization (WHO) said,
doubting the need to ban imports of
chicken meat by some countries.

Most people with bird flu have signs and
symptoms of conventional influenza.
Some also develop life-threatening
complications such as viral pneumonia and
acute respiratory distress syndrome
But the greatest complication of bird flu is
still hypothetical
SOLUTIONS
 No
 But
specific treatment
now, the primary treatment option
remains the flu drug oseltamivir (Tamiflu),
that works by preventing the virus from
escaping its host cell
Sanitary prophylaxis

Avoidance of contact between poultry and wild birds,
particularly waterfowl

Avoidance of the introduction of birds of unkown health
status into a flock

Control of human traffic

Proper cleaning and disinfection procedures

Practice an “all in-all out” system in the poultry farm
In outbreaks
 Slaughtering
of all birds
 Disposal
of carcasses and all
poultry products
• Cleaning and
disinfection
• Allow at least 21
