Hong Kong and Taiwan authorities confirmed their first case of H1N1 in swine November 5, reported Beijing’s state-run China News Service (CNS).

Hong Kong Food and Health Bureau announced the H1N1 virus was found in two pigs but failed to trace the source of those infected pigs, said the report.

Local pig farms have been urged by Hong Kong Food and Health Bureau to familiarize themselves with measures needed to prevent the spread of H1N1, according to CNS. Also, Hong Kong government plans to tighten inspections of live pigs from mainland China.

In addition, more than 100 pigs from a pig farm in Taidong County started showing H1N1 symptoms, following three confirmed cases of H1N1 there, according to Guo Xusong, an official at Taiwan Disease Control Bureau.
