WHO says 277,607 cases of H1N1, at least 3,205 deaths across the world. The death rate is only 1%
The World Health Organization (WHO) said Friday that the number of cases of the pandemic flu H1N1 2009 has passes the figure of 277,607 with at least 3,205 deaths.
WHO said in its update that in the temperate region of the southern hemisphere (represented by countries such as Chile, Argentina, Australia, New Zealand, and South Africa), influenza activity continues to decrease or return to baseline.
Active transmission persists in tropical regions of the Americas and Asia. Many countries in Central America and the Caribbean continue to report declining activity for the second week in a row. However, countries in the tropical region of South America (represented by countries such as Bolivia, Ecuador, and Venezuela) are reporting increasing levels of respiratory disease.
In the tropical regions of Asia, respiratory disease activity remains geographically regional or widespread but the trend is generally increasing as noted in India, Bangladesh, and Cambodia.
While in the temperate regions of the Northern Hemisphere activity is variable. In the United States, regional increases in influenza activity are being reported, most notably in the south eastern states. Most of Europe is reporting low or moderate respiratory diseases activity, but parts of Eastern Europe are beginning to report increases in activity.
WHO said that the pandemic (H1N1) influenza virus continues to be the predominant circulating virus of influenza, both in the northern and southern hemisphere. All pandemic H1N1 2009 influenza viruses analysed to date have been antigenically and genetically similar to California/7/2009-like pandemic H1N1 2009 virus.
The US Centers for Disease Control and Prevention this week reported on an analysis of 36 fatal pandemic influenza cases in children under the age of 18 years. Sixty-seven percent of the children had one or more high-risk medical conditions, most commonly neurodevelopmental disorders. In addition, 10 of 23 children for whom data were available were found to have strong evidence of secondary bacterial co-infections
