H1N1 Pandemic swine flu toll reaches 16,713: WHO

Pandemic H1N1 Swine flu has claimed at least 16,713 lives around the world since it was first uncovered in Mexico and the United States last April, the World Health Organisation said Friday.

The pandemic, which has spread to 213 countries and territories, has since waned in much of Europe and North America, but data indicated that transmission may be increasing in West Africa.

"In Sub-Saharan Africa, limited data suggests that on-going community transmission of pandemic influenza virus continues to increase in parts of West Africa, without clear evidence of a peak in activity," said the WHO. More cases were being detected in Senegal, Ivory Coast and Rwanda, it said.

The A(H1N1) virus was also spreading in Southeast Asia, with transmission "most active in Thailand," added the UN health agency.
