WHO - Pandemic (H1N1) 2009 - update 89

WHO's latest update on the H1N1 situation worldwid. Excerpt from an informative update, the paragraph which is of the interest to all of us here in Malaysia and South East Asia.

" In Southeast Asia, pandemic influenza virus continued to circulate in areas, however, the overall intensity of respiratory diseases activity remained low and unchanged, except in a few countries. In Brunei Darussalam, during February 2009, influenza activity was reported to be geographically widespread and was associated with an increasing trend and high intensity of respiratory diseases. Both Myanmar and Thailand have reported an increasing trend of respiratory diseases associated with geographically regional spread of influenza for the first half of February 2009, however, overall intensity currently remains low in both countries. In Thailand, approximately one third of provinces reported that >5% of medical visits were due to ILI during the most recent reporting week. In East Asia, virologic surveillance data suggest that pandemic influenza and seasonal influenza type B viruses continue to co-circulate. A recent increase in ILI activity in Mongolia may be due to an increase in the circulation of seasonal influenza type B viruses. Overall influenza activity continues to decline and return to baseline levels in both Japan and the Republic of Korea (S. Korea). In Hong Kong SAR (China) and in Chinese Taipei, pandemic influenza virus continues to circulate at low levels and overall ILI activity is substantially lower than what was observed peaks of activity during the fall months. In South Asia, overall influenza activity remained low, however, pandemic influenza virus transmission persists in the western part of India. "
