On 10 August 2010, the World Health Organization (WHO) declared that the H1N1 influenza pandemic was officially over. We have now entered the post-pandemic period.

However, it is important not to ignore H1N1 flu.

The H1N1 flu virus will be one of the main viruses circulating this winter. Therefore, WHO has announced that the H1N1 flu virus will be included in the 2010-11 seasonal flu vaccine.
