The World Health Organization (WHO) today submitted its regular update report highlighting the fact that Flu activity has once again picked up the steam and the affected Southern Hemisphere has several countries reporting the affect.

The names that were mentioned primarily in the list were Australia, New Zealand, Bolivia, and Brazil. Talking about Australia, the WHO report showed that the positive respiratory samples have almost doubled this year with New South Wales, Queensland, and South Australia reporting the highest number of cases. The figures have reported a 30 increase from the previous reporting period. H3N2 is the dominant virus detected. Influenza B follows the track.

New Zealand is also reporting somewhat similar trend as the proportion of doctor visiting the flu-like illness patients has shown a rise. The figures this year are showing an increase over the national baseline of 50 consultations per 100,000 population. More than 70 percent cases have been detected with H3N2 virus. Influenza B, H1N1, and un-subtyped influenza A are also influencing the people's health.

As far as South Africa is concerned then flu activity is continuing here too. H3N2 has been detected to be affecting almost half of the respiratory specimens. Influenza B is also playing its game. In Bolivia, La Paz has been detected with the highest flu cases of H1N1 virus. Flu infections from former pandemic virus are high in Brazil.
