Excerpted from this week's Flu News Europe:
Week 4/2018 (22–28 January 2018)
• Influenza activity was widespread in the majority of reporting countries and while activity was increasing, intensity in most countries was reported as low to medium.
• Both influenza virus types A and B were co-circulating with a higher proportion of type B viruses. Different proportions of circulating influenza virus types and A subtypes were observed between countries in the Region.
• Of the individuals sampled, on presenting with ILI or ARI to sentinel primary healthcare sites, 51.9% tested positive for influenza viruses, within the range observed in the previous 3 weeks (42–52%).
