The flu season has approached and so have the countries started reporting flu activities. The latest upswing in the cases has been reported by Southern Hemisphere countries like Australia, New Zealand, Bolivia and Brazil.

The above facts are being reported by the World Health Organization (WHO), which today announced its report on regular updates and cleared the figures of several different countries.

Australia is reporting double number of positive respiratory samples. The cases have increased by almost 30 percent from the previous reporting period. New South Wales, Queensland, and South Australia were the regions that reported highest affect of H3N2 and influenza B virus, the dominant viruses noted.

New Zealand reported 50 consultations per 100,000 population (doctors visiting for flu-like illness). H3N2 has again been found to be the dominant one playing the game with more than 70 percent reporting symptoms of the virus. Influenza B, H1N1, and influenza A, have also been detected.

H3N2 is again at top to be affecting the South Africa people. Influenza B is following the list and causing problems, says WHO.

Bolivia is reporting an increase in flu detections around La Paz and this region seems to be under the grip of H1N1 virus. Brazil is nowhere behind because it has also come up with many cases of flu infections.
