Risk assessment

29 Nov 2011

CDC has reported recent infections in children in North America with a swine-origin triple reassortant influenza A(H3N2) virus that includes a genetic component from the pandemic 2009 virus, and with probable human-to-human transmission with these viruses.

Executive summary

Centers for Disease Control and Prevention (CDC) has reported recent infections in children in North America with a swine-origin triple reassortant influenza A(H3N2) virus that includes a genetic component from the pandemic 2009 virus, and with probable human-to-human transmission with these viruses.

ECDC has conducted a rapid risk assessment to evaluate the implications for public health in Europe.

Swine influenza

Swine influenza is a respiratory disease of pigs caused by type A influenza viruses that regularly cause outbreaks of influenza in pigs. Influenza viruses that commonly circulate in swine are called “swine influenza viruses” or “swine flu viruses.” Like human influenza viruses, there are different subtypes and strains of swine influenza viruses.

Avian influenza

Avian influenza is an infectious viral disease in birds, including domestic poultry. Avian influenza is mainly found in birds, but under certain circumstances infections can also occur in humans even though the risk is generally very low.
