More bad news on polio
Well this is just fantastic:
More than 40 new cases of polio have been confirmed in Yemen, the World Health Organization said yesterday, more new cases than in any other nation. "It's a much bigger outbreak than we originally thought, and it's spread throughout the country," said Dr. David L. Heymann, who is in charge of the W.H.O. polio-eradication campaign.See my previous posts about vaccines here, here, here, and here.
Epidemiologists expect the 63 cases confirmed thus far in Yemen, a poor country on the southern tip of the Arabian peninsula, to grow to more than 100 soon. ... But transmission usually soars in the late summer rainy season, and some districts in any country report more promptly than others, so it is too early to tell which country will end the year with the most cases.
