Communicable disease threats reports on avian influenza viruses
The ECDC Communicable Disease Threats Report (CDTR) is a weekly bulletin for epidemiologists and health professionals on active public health threats.
Epidemiological updates on avian influenza viruses
Situation updates on a currently evolving outbreak or a public health threat. The epidemiological updates typically contain a description of case numbers, temporal and geographic distribution, as well as age and sex distribution. It can also include information on the identified or potential risk factors and assessments.
Risk assessments on avian influenza viruses
Rapid risk/outbreaks assessment aim at supporting the countries and the European Commission in their preparedness and response to a public health threat. They provide a timely summary and risk assessment of a public health threat for EU/EEA countries related to a specific event. They also include potential options for response. As outbreaks or public health events develop, ECDC may issue updated risk assessments.
Novel avian influenza A(H7N9) virus outbreak
In 2013, a novel avian influenza A(H7N9) virus was detected in patients in China and cases are still being reported. No autochthonous cases have been reported outside China. Most cases are isolated, and sporadic zoonotic transmission from poultry to humans is the most likely explanation for the outbreak.
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: Severe respiratory disease associated with a novel influenza A virus, A(H7N9) China
On 31 March 2013, the Chinese authorities announced the identification of a novel influenza A virus, A(H7N9), in three seriously ill people from two provinces presenting with respiratory infections. So far, no epidemiological link has been identified between those three patients. When testing for the influenza virus, the Chinese Center for Disease Control and Prevention identified genes from both A(H7N9) and A(H9N2) viruses, thus indicating a novel reassortant avian influenza A virus. In its initial assessment of the situation, the ECDC rapid risk assessment concludes that the risk of the spread of the virus in Europe can be considered low at this stage.
Influenza A(H7N9) virus in China - implications for public health - 7th update, 3 July 2017
Since the notification of a novel reassortant influenza A(H7N9) virus on 31 March 2013, 1 548 laboratory-confirmed cases of human infection with avian influenza A(H7N9) virus have been reported.
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.
Rapid Risk Assessment: Human infection with influenza virus A(H7N9) virus - 4th update, 3 February 2015
This fourth update of the risk assessment on human infection with avian influenza A(H7N9) virus, summarises the epidemiological and virological information on the disease in China and Canada, and assesses the risk to public health in the EU/EEA and to EU/EEA citizens.
