Abstract
Six hundred and five sera samples were collected from apparently
healthy local chickens in thirty three villages in twelve Local
Government Areas of Kaduna State. Six of the Local Government
Areas had outbreak of highly pathogenic avian influenza that was
reported and confirmed between 2006 and 2007. The remaining
six Local Government Areas were randomly selected from those
Local Government Areas that did not report outbreak of highly
pathogenic avian influenza during the same period.
Hemagglutination inhibition test was conducted to detect
antibodies to low pathogenic avian influenza virus (H5N2) while
structured questionnaires were administered to one hundred and
seventy two (172) farmers to determine their knowledge, level of
awareness and readiness to disclose outbreak of highly
pathogenic avian influenza. The overall prevalence rate of
antibodies to low pathogenic avian influenza virus (H5N2) was
18.1%. A higher prevalence rate of (27.3%) was recorded in Local
Government Areas that did not report outbreak of HPAI
compared to the prevalence rate of 7.5% in the Local Government
Areas that reported outbreak of HPAI. The result of this study
shows that low pathogenic influenza virus (H5N2) is circulating
among local chicken population in Kaduna state.
There was association between the presence of ducks and
detection of antibodies to low pathogenic H5N2 virus (χ2 =24.257
df =1). Most of the farmers (84.9%) were aware of HPAI. Majority
(87.2%) also said they would report outbreak of HPAI but the
knowledge of the disease was low (19.8%) among farmers.
Educational status (χ2 = 16.635 df = 5) and occupation (χ2 = 9.984
df = 4) of farmers had association with the knowledge of HPAI.
Majority (78.5%) of farmers heard of HPAI through the radio. This
may explain why the knowledge of the disease is low. It is
recommended that surveillance to establish the presence or
absence of LPAI (H5N2) and other LPAI should be enhanced and
sustained. More efforts should also be made to improve the
knowledge and recognition of HPAI by local poultry farmers. This
will go a long way in aiding the Federal Government’s control
program of the disease.
