For week 20/2014:
• Low-intensity influenza activity was reported by 25 reporting countries.
• Of 68 sentinel specimens tested across 17 countries, six (9%) were positive for influenza virus.
• No hospitalised, laboratory-confirmed influenza cases were reported.
With influenza activity continuing to decline in all reporting countries, after five months of active transmission, the 2013–14 influenza season is coming to an end. During this season, A(H1N1)pdm09 and A(H3N2) viruses co-circulated in almost equal proportions. The intensity of the season was low in many countries throughout the season and only reached high intensity in three countries.
This is the last weekly report for the 2013–14 influenza season. The next report will be issued for data covering weeks 21–30/2014.
