Abstract

The study appraised local poultry biosecurity risks to highly pathogenic avian influenza by assessing farmers' knowledge, beliefs and poultry practices using a standard questionnaire. Farmers' knowledge on transmission and prevention was high but low on disease recognition. Radio was ineffective at informing Islamic educated farmers. Extensive knowledge on transmission and protection did not result in behavioural change as farmers engaged in risky practices of selling, eating or medicating infected poultry and not reporting poultry death. Islamic educated farmers do not believe highly pathogenic avian influenza is a serious and preventable disease. Women are more likely to self medicate when experiencing influenza-like illness. Audio-visual aids would improve avian influenza recognition while involvement of community leaders would enhance disease reporting. Outbreak of highly pathogenic avian influenza in local poultry in Nigeria would follow a similar pattern in Southeast Asia if the risk perception among farmers is not urgently articulated.

Perhaps it is useful to read again this abstract of an article by Webster and others:

Abstract

To determine the extent of animal influenza virus circulation in C?te d?Ivoire, Benin, and Togo, we initiated systematic year-round active influenza surveillance in backyard birds (predominantly chickens, guinea fowl, and ducks) and pigs. A total of 26,746 swab specimens were screened by using reverse transcription PCR. Animal influenza prevalence was estimated at 0 (95% CIs for each of the 2 study years 0?0.04% to 0?1.48% [birds] and 0?0.28% to 0?5% [pigs]). In addition, 2,276 serum samples from the same populations were negative for influenza-specific antibodies. These data indicate that the environments and host populations previously identified as harboring high levels of influenza virus in Southeast Asia do not do so in these 3 countries. The combination of climate and animal density factors might be responsible for what appears to be the absence of influenza virus in the backyard sector of the 3 countries.
