  1. Domestic Ducks as Potential Reservoir of Avian Influenza Virus in Post HPAI H5N1 Outbreak Area, Sunyani Municipality. Vitus Burimuah (DVM) Ghana Field Epidemiology and Laboratory Training Program (GFELTP).

  2. Introduction • Avian influenza (AI) is a viral disease of varied etiology. • Naturally affects avian species. • Also affects swine, equine and man. • Waterfowls are asymptomatic carriers of AI virus infection. • Threat of a pandemic due to worldwide spread. • History of HPAI H5N1 outbreak in poultry in study area , May 2007.

  3. Objectives General • Determine the presence of H5N1 in ducks in the Sunyani Municipality. Specific • Determine the prevalence of AI virus in duck populations. • Characterize any AI viruses circulating in the study area. • Assess adherence to bio-security measures in duck farms.

  4. Methods 1/2 • Brong Ahafo region • Population177,301 (2012 census) • 60% of inhabitants into agric. • Poultry population 2,503,559, 1% ducks (MOFA, 2005)

  5. Methods 2/2 Data Collection, Processing and Analysis. rRT-PCR Cloacal swabs (384) RNA Extraction and purification Test results DATA COLLECTION Data analysed Questionnaire administration • 48 farm workers interviewed • Biosecurity • Husbandry

  6. Results • All 384 samples tested NEGATIVE for Influenza Type A viruses. • No circulating AIV was detected. • Disinfection not patronized by 67% (32/48) of respondents. • 89% (14/16) of bio-security practices investigated were not observed.

  7. Conclusion • There was no evidence of AI virus infection in domestic ducks in the study area. • Bio-security adherence was poor in the 9 sites. • There is a strong risk of re-introduction and spread of the HPAI AI virus. • Continuous surveillance necessary for early detection and response.

  8. Public Health Action • VSD has strengthen existing surveillance activities for AI in high risk areas. • VSD has intensified bio-security, poultry management and sanitation awareness creation among farmers and the public. • VSD now monitors poultry farms to ensure bio-security practices are adequately applied.
