Epidemiological comments | The affected farms are turkey breeding premises belonging to the same company, vertically integrated, where appropriate biosecurity measures are applied. Outbreak no. 1 is composed of 5 breeding premises. The outbreak started in premises no. 1 and through horizontal transmission, it reached 3 other premises. In the outbreak n. 2 of 5 existing sectors are affected. Prior to the appearance of clinical signs, some birds were exposed to people showing respiratory symptoms. The affected premises were systematically monitored through serological testing with negative results until 28 July 2009. Serotyping allowed to exclude the presence of H5 and H7 virus and allowed to confirm detection of A/H1N1 2009 pandemic influenza virus 2009. Samples were sent to the Public Health Institute of Chile (ISP), Ministry of Health. The ISP confirmed the presence of A/H1N1 2009 pandemic influenza virus 2009 using real time PCR. The RT-PCR for seasonal H1 and H3 influenza resulted negative. Samples will be sent to the OIE Reference Laboratory. |
