Global flu activity remains low

Influenza

According to the biweekly flu update from the World Health Organization, local or regional flu influenza outbreaks in a small number of countries were the only exceptions to a global pattern of low flu activity.
 
The update, which covers November 6 through 19, said that flu activity is low overall in the Northern Hemisphere and holds true for the United States. The incidence of influenza was likewise low in the Southern Hemisphere as well, CIDRAP News reports.
 
In Europe, the Netherlands was the only country with localized flu outbreaks. The country reported influenza A/H3N2 and B cases.

Cambodia continued to deal with regional flu activity involving 2009 pandemic H1N1 and B viruses in Asia, but there were few cases elsewhere on the continent.
 
Nicaragua continued to have outbreaks of pH1N1 and H3N2 viruses, though the rest of Central America reported little flu, CIDRAP News reports.

In the Southern Hemisphere, the highest incidence was found in Cameroon, which saw local outbreaks of pH1N1, H3N2 and B strains. The rest of the hemisphere had only sporadic cases of influenza.
 
According to the WHO, 80 countries and territories reported a total of 1,056 specimens testing positive for flu during the two weeks. Of those specimens, approximately 58 percent were influenza A and 42 percent were type B. Of the A isolates, 68.6 percent were H3N2 and 31.4 percent were pH1N1.
 
In the United States, local flu activity was reported in Massachusetts, while sporadic flu activity was reported in the District of Columbia, Guam and 28 other states. The U.S. Virgin Islands and 21 states had no flu activity to report.
