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.
Epidemiological update: H3N2v cases in Ohio, US, 4 September 2014
In August 2014, the US Centers for Disease Control and Prevention (CDC) reported two laboratory-confirmed human infections with a A(H3N2) variant influenza virus of swine origin A(H3N2)v in Ohio, USA.
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.
ECDC rapid risk assessment: Human cases of swine influenza without apparent exposure to pigs, United States and Mexico
On April 21, the United States reported on the existence of 2 human cases of swine influenza A (H1N1) infection. On 23 April, through intensified surveillance efforts, a total of 7 confirmed human cases of swine influenza A (H1N1) infection, were reported.
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.
CNRL in silico exercise to determine the capabilities of network laboratories to detect triple reassortant swine origin influenza A(H3N2) viruses
Following the emergence of swine influenza A(H3N2) variant (v) viruses with sporadic human infections in North America, the Community Network of Reference Laboratories (CNRL) and the Animal Health and Veterinary Laboratories Agency completed an exercise to assess the CNRL’s capability to detect novel reassortant and circulating triple reassortant swine viruses (TRA) in humans.
Risk assessment: Swine-origin triple reassortant influenza A(H3N2) variant viruses in North America
Following recent increased reporting of human infections in the US with an influenza A(H3N2) variant virus of swine origin (A(H3N2)v), ECDC has updated its risk assessment. It concludes that the swine-origin influenza A(H3N2)v viruses do not currently pose a serious risk to human health in general and Europe in particular.
Rapid risk assessment: Risk related to the use of ‘do-it-yourself' CRISPR-associated gene engineering kit contaminated with pathogenic bacteria
On 24 March 2017, the German authorities reported the contamination of a ‘do-it-yourself’ bacterial gene engineering CRISPR kit produced in the US. This publication assesses the risk related to the use of ‘do-it-yourself’ CRISPR-associated gene engineering kit contaminated with pathogenic bacteria.
