Week 1/2019 (31 December 2018–6 January 2019)
Influenza activity continued to increase in the European Region. Of the individuals sampled after presenting with ILI or ARI to sentinel primary health care sites, 44.6% tested positive for influenza viruses.
The majority of influenza virus detections were type A in both inpatients and outpatients.
Both influenza A(H3N2) and A(H1N1)pdm09 viruses were detected.
- Data from the 21 Member States and areas reporting to the EuroMOMO project indicated all-cause mortality was at expected levels for this time of year.
2018/19 season overview
Influenza activity in Europe is increasing, with both subtypes of type A viruses circulating widely. Countries should continue to encourage vaccination.
Most of the hospitalized laboratory confirmed influenza infections were associated with A(H1N1)pdm09 virus and were in persons aged 15-64 years.
- The predominant A(H1N1)pdm09 and A(H3N2) viruses circulating match the vaccine components, although relatively low numbers of influenza A(H3N2) viruses have been characterized and concerns related to egg-adaptation of the virus during production persist, as in previous years.
- The northern hemisphere Vaccine Composition Meeting for 2019–2020 has been planned for 18–20 February 2019 in Beijing, China. For more information see here.
