Rapid risk assessment: Potential resurgence of highly pathogenic H5N1 avian influenza
The increased reports of A(H5N1) outbreaks in poultry and wild bird populations, and the emergence of a further evolved lineage of the virus in poultry in some countries, do not change the current assessment of the risk to human health.

Rapid risk assessment: A(H5N1) Highly Pathogenic Avian Influenza in Egypt – Implications for human health in Europe
Highly pathogenic avian influenza A(H5N1) infections are continuing to occur in poultry and humans in Egypt. However there is no evidence of a significant change in the pattern of human illness and deaths related to A(H5N1) virus infections in the country. Certainly there are no epidemiological data or analyses consistent with adaptation of these viruses to humans.

ECDC rapid risk assessment: Reassortment seasonal influenza virus and swine influenza virus
New strain of swine influenza identified in two workers on a pig farm in Canada. Swine influenza (SI) is an acute viral infection of the respiratory tract in pigs. Subclinical infections are also common. The mortality is low and recovery usually occurs within 7-10 days.

Risk assessment: Swine-origin triple reassortant influenza A(H3N2) viruses in North America
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.

Swine-origin triple reassortant influenza A(H3N2) viruses in North America
ECDC published an update of its previous rapid risk assessment on Swine-origin triple reassortant influenza A(H3N2) viruses in North America. This rapid risk assessment updates that of 29 November 2011, with a focus on the epidemiological information and a report on progress made to address the diagnostic needs in the European Union that will enable detection of these new viruses.

Rapid risk assessment: Human fatality from highly pathogenic avian influenza A(H5N1) virus infection in Guangdong province, China
Following reports of a human fatality due to highly pathogenic avian influenza A(H5N1) virus infection in China’s Guangdong province, the European Commission requested an update to the assessment of risk of human-to-human transmission occurring. ECDC does not consider that there is any change to the previous assessments that the risk for EU/EEA countries is very low.
