Influenza A/H1N1: 18 October
18 October 2009
U.S.A.
During the week of October 4-10, 2009, influenza activity continued to increase in the United States as reported in FluView. Flu activity is now widespread in 41 states. Nationwide, visits to doctors for influenza-like-illness continued to increase and are now about equal to or higher than what is seen at the peak of many regular flu seasons. In addition, flu-related hospitalizations and deaths are continuing to go up and are above what is expected for this time of year. See More On Key Flu Indicators.

Europe
The pandemic (H1N1) 2009 is spreading across Europe. Only Spain and the United Kingdom report fatal cases since the last E-CDC update. See list of national cases.

Scandinavia
The influenza activity is increasing in Sweden, with almost only pandemic H1N1 being detected. The activity in Norway is stable with sporadic cases of pandemic H1N1, but so far no increased activity have been detected. The Finnish National Institute for Health and Welfare reports 377 cases in total.
The activity in Denmark has been increasing since week 39.

Comment
With the activity increasing in the United States and Europe including Scandinavia, the pandemic situation is approaching.  New isolates are almost entirely H1N1 and it is expected that the pandemic H1N1 will replce - or has replaced - the previous seasonal H3N2 influenza.

The first doses of H1N1 vaccine has been delivered for vaccination of risk groups. If you think you belong to a risk group follow the information on the website of your national health authorities.
