The World Health Organization (WHO) has notified a human case of swine-origin influenza A(H1N2) virus infection. Most human cases result from exposure to swine influenza viruses through direct contact with infected swine or contaminated environments. Ongoing investigations are in place to identify the source of the infection and to characterize the risks of this influenza variant virus.
WHO assesses the risk of spread of swine-origin influenza viruses through humans and/or community-level spread among humans as low. It is very important to continue global surveillance to detect virological, epidemiological, and clinical changes associated with circulating influenza viruses that may affect human and animal health.
