The domestic pig of Southern China will be submitted to influenza virus surveillance studies. This is because (A) Southern China is now recognized as a hypothetical influenza epicentre, the pig a "mixing vessel" for the two-way transmission of influenza viruses between the domestic duck, the prime influenza virus reservoir, and man and that it is now 28 years since the Hong Kong virus first appeared in man and (B) recent surveillance studies of pigs have detected purely avian influenza virus. It is now of even greater importance to know whether natural reassortants of pandemic potenital still exist with the potential of crossing the species barrier to humans.
