Epidemiological comments | A/H1N1 influenza virus surveillance programme began since January 2009 in the country. Clinical signs such as coughing and diarrhoea were observed in a pig farm located in T’ai-Tung County on 19 October 2009.

Samples were collected and sent to the Animal Health Research Institute. Disinfection and cleaning of the index farm has been conducted and completed. Movement control has been also implemented. The positive results of virus isolation, real-time RT-PCR and gene sequencing demonstrated that this outbreak was caused by H1N1 influenza A virus. The sick pigs in the index farm have recovered. One pig farm within 1km radius of the index farm has been under vigilant monitoring and no clinical or epidemiological evidence of infection has been found. Seven pig farms within 3km radius of the index farm have also been under intensive monitoring. |
