Situation overview: highly pathogenic avian influenza virus A of H5 type, 2 December 2015
This risk assessment looks at the risks of transmission in the EU/EEA and the options for response in connection with this localised outbreak.
Epidemiological update: increase in reporting of human cases of A(H5N1) influenza, Egypt, 9 April 2015
Epidemiological update: increase in reporting of human cases of A(H5N1) influenza, Egypt
Rapid risk assessment: Human infection with avian influenza A(H5N1) virus, Egypt - 1st update, 13 March 2015
Human cases and fatalities due to influenza A(H5N1) virus continue to increase in Egypt, with cases from the country now accounting for the highest number of human cases reported worldwide.
Rapid risk assessment: human infection with avian influenza A(H5N1) virus, Egypt, 23 December 2014
According to a WHO update published on 4 December 2014, eight new human cases of influenza A(H5N1) have been reported in Egypt, with onset of disease in November 2014, bringing the total for 2014 to 12.
Rapid risk assessment: Human infections with avian influenza A viruses, China
This Rapid Risk Assessment summarises the latest information about human infections with avian influenza A viruses in China.
Epidemiological update: avian influenza A(H5N1), 8 January 2014
On 8 January 2014, Canada reported a fatal imported case of influenza A(H5N1) infection. This is the first confirmed human case of H5N1 in North America.
Risk assessment: Laboratory-created A(H5N1) viruses transmissible between ferrets
The results of two, as yet unpublished, investigations of laboratory-induced genetic changes in avian influenza A(H5N1) viruses have been reported to have found that a surprisingly few number of changes make the viruses transmissible between ferrets, the most commonly used model for the way influenza behaves in humans. The possibility that this could have resulted in the development in laboratories of A(H5N1) influenza viruses transmissible between humans has caused concern for public safety and generated unusually high levels of debate in the scientific community. This report summarises and explains the complex public health and scientific issues around these developments including the positive and negative aspects of some of the responses that have been proposed internationally.
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.
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.
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.
