ECDC rapid risk assessment: Influenza of possible swine origin in human in Spain
Influenza of swine origin detected retrospectively in a human with illness in November 2008. 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: 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The results of two, as yet unpublished, investigations of laboratory-induced genetic changes in avian influenza A(H5N1) viruses have been reported to have found that a surprisingly few number of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.
Human infection with a novel avian influenza virus, A(H7N9), China - 2nd update, 8 May 2013
This second update to ECDC's initial risk assessment concludes that the risk of the disease spreading to Europe via humans or through poultry is still low at this time.
Rapid risk assessment on influenza A(H7N9) China, 12 April 2013
On 31 March 2013, Chinese authorities announced the identification of a novel reassortant A(H7N9) influenza virus isolated from three unlinked cases of severe respiratory disease in eastern China. This is the first time that human infection with avian influenza virus A(H7N9) has been identified.
Since then, human cases have continued to be reported from eastern China. As of 11 April, there were 38 laboratory-confirmed cases including ten deaths reported from four bordering provinces with a concentration of cases in and around Shanghai. Cases occur sporadically, without obvious epidemiological links. There is currently no confirmed human-to-human transmission.
Expert opinion on neuraminidase inhibitors for the prevention and treatment of influenza - review of recent systematic reviews and meta-analyses
This ECDC expert opinion confirms earlier assessments by ECDC and national authorities that there is no significant new evidence to support any changes to the approved indications and recommended use of neuraminidase inhibitors (NAIs) in EU/EEA Member States.
Scientific opinion on the possible risks posed by the influenza A (H3N2v) virus for animal health and its potential spread and implications for animal and human health
Swine are an important host in influenza virus ecology since they are susceptible to infections with both avian and human influenza A viruses.
Avian influenza A/H5N1: Collected risk assessments, technical guidance to public health authorities and advice to the general public
The document determines the risk to human health in Europe from highly pathogenic avian influenza viruses in birds and animals and identifies areas requiring additional scientific and public health work both as single pieces of work and for risk monitoring by ECDC and its partners.
Risk assessment: The Public Health Risk from Highly Pathogenic Avian Influenza Viruses Emerging in Europe with Specific Reference to type A/H5N1
The document characterises the risk to human health in Europe from highly pathogenic avian influenza viruses in birds and animals. The report identifies areas requiring additional scientific and public health work both as single pieces of work and for risk monitoring by ECDC and its partners.
Risk assessment: The Public Health Risk from Highly Pathogenic Avian Influenza Viruses Emerging in Europe with Specific Reference to type A/H5N1 Version June 1st 2006
The objective of this revised document is to further determine the risk to human health in Europe from highly pathogenic avian influenza viruses in birds and animals. Specifically the additional risk that arises from the recent emergence and extension of A/H5N1 viruses into the European Union and elsewhere in the world, and the changed biology of the viruses among wild and domestic birds.
