INTRODUCTION: WHAT IS
AVIAN INFLUENZA

Nigeria poultry population is estimated at 140 million, with backyard
farmers accounting for 60% of poultry producers.

Avian influenza is a disease caused by viruses adapted to birds and other
species. The virus infects all domestic and wild birds characterized by
respiratory, digestive and in some cases nervous signs and high morbidity
and mortality. Incubation period ranges from a few hours to 2 weeks
depending on the virus dose, route of infection and species of birds.

These viruses can be divided into highly pathogenic (HPAI) and low
pathogenic (LPAI) strains based on its ability to cause disease in poultry.

Influenza viruses are divided into subtypes based on two proteins that they
have on their surface;
Haemaglutinin (H)
Neuraminidase (N)

INTRODUCTION OF A.I CONTD

The H5N1 virus is the strain of avian influenza is the most
common and deadliest which has infected numerous species
of birds in Asia, Europe and Africa since the end of 2003.

H5N1 strain can be transmitted to humans, although this is
very difficult unless they come into close contact with
infected birds.

The H5N1 infection may follow an unusually aggressive
clinical course, with rapid deterioration and high fatality.
Primary viral pneumonia and multiple organ failure have
been common among people who have become ill with H5N1
influenza.

been dying in Jigawa state between December, 2005 and early

However,the first confirmed case of AI was found at Kaduna
on January 14th 2006,later Kano state with birds reported
dying due to an unknown disease condition from which
chemotherapy and supportive care proved abortive in many
cases.

ECONOMIC IMPACT OF AVIAN
INFLUENZA

Socio-economic Impact, an Avian Influenza outbreak would
create general panic among the public which would lead to
boycott of poultry products such as live stock trading,
restaurants and fast food, and would result in sharp decline in
sales and prices.

An Avian Influenza outbreak would lead to unemployment, as
most farm would close down, other poultry related industries
would also be affected.

Mainly, the poultry Feed industry would also be greatly affected
as prices and other related products used in formulation of feeds
would drop drastically.

All the above mentioned points would affect the economy of the
Nation as a whole
