WHO advises no restriction of regular travel or closure of borders.It is considered prudent for people who are ill to delay international travel and for people developing symptoms following international travel to seek medical attention, in line with guidance from national authorities.

Canada on 2 May reported the identification of the A(H1N1) virus in a swine herd in Alberta. It is highly probable that the pigs were exposed to the virus from a Canadian farm worker recently returned from Mexico, who had exhibited flu-like symptoms and had contact with the pigs. There is no indication of virus adaptation through transfer from human to pigs at this time.

There is no risk of infection from this virus from consumption of well-cooked pork and pork products.

Individuals are advised to wash hands thoroughly with soap and water on a regular basis and should seek medical attention if they develop any symptoms of influenza-like illness.
