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.

Comparing introduction to Europe of highly pathogenic avian influenza viruses A(H5N8) in 2014 and A(H5N1) in 2005 Eurosurveillance, vol 19, issue 50
Since the beginning of November 2014, nine outbreaks of highly pathogenic avian influenza virus (HPAIV) A(H5N8) in poultry have been detected in four European countries. In this report, similarities and differences between the modes of introduction of HPAIV A(H5N1) and A(H5N8) into Europe are described. Experiences from outbreaks of A(H5N1) in Europe demonstrated that early detection to control HPAIV in poultry has proven pivotal to minimise the risk of zoonotic transmission and prevention of human cases.
