This is the first time that reassortment of swine influenza virus with the pandemic H1N1 virus was found in the surveillance programme. Prof Malik Peiris, the HKU expert in charge of the surveillance programme, considered that the findings of reassortment between the pandemic H1N1 virus and swine influenza virus was not totally unexpected. These events were likely occurring worldwide and its detection in Hong Kong was purely the consequence of intensive surveillance.Further tests are being conducted by HKU to determine if there are any particularcharacteristics of this strain.
