So in another UN blunder, they somehow managed to spread cholera into Haiti.

PORT-AU-PRINCE, Haiti  It began as a rumor that farmers saw waste from a U.N. peacekeeping base flow into a river. Within days of the talk, hundreds downstream had died from cholera.

The mounting circumstantial evidence that U.N. peacekeepers from Nepal brought cholera to Haiti was largely dismissed by U.N. officials. Haitians who asked about it were called political or paranoid. Foreigners were accused of playing "the blame game." The World Health Organization said the question was simply "not a priority."

But this week, after anti-U.N. riots and inquiries from health experts, the top U.N. representative in Haiti said he is taking the allegations very seriously.

"It is very important to know if it came from (the Nepalese base) or not, and someday I hope we will find out," U.N. envoy Edmond Mulet told The Associated Press.

The answer would have implications for U.N. peacekeeping missions around the world, he said.

It would affect the relationship between the U.N. and Haiti: If its peacekeepers misled, it could lose credibility for tasks such as helping oversee next week's election. It could affect the job of U.N. humanitarian workers, who work separately from the peacekeepers.

It would help answer scientific questions: Is the source still out there? How does this cholera strain spread? Does it pose a threat to the region, including the southern United States?

In 2009 the World Health Organization decided to give live vaccines to people in Nigeria, were it can then mutate into other more deadlier versions.

LONDON  Polio is spreading in Nigeria and health officials say in some cases it's caused by the vaccine used to fight the paralyzing disease.

In July, the World Health Organization issued a warning that this particular virus might extend beyond Africa. So far, 124 Nigerian children have been paralyzed this year about twice those afflicted in 2008.

Nigeria and most other poor nations use an oral polio vaccine because it's cheaper, easier, and protects entire communities. But it's made from a live polio virus which carries a small risk of causing polio. In even rarer instances, the virus in the vaccine can mutate into a deadlier version that ignites new outbreaks.

A virologist with the U.S. Centers for Disease Control and Prevention says genetic analysis proves such mutated viruses have caused at least seven separate outbreaks in Nigeria.

The vaccine used in the United States and other Western nations is given in shots, which use a killed virus that cannot cause polio.
