Chinese researchers studying a 24-year old pregnant Chinese woman who had died of Avian Flu say that bird flu can be spread to the fetus! The fetus in this woman had been infected.
"He said that as well as being found in the woman's placenta, the virus was detected in the alimentary canal, brain, blood cells and respiratory tract of both victims. It was also found in the lungs and liver of the fetus."
It doesn't seem like they're too worried thought.
"'So far, no substantiated case of interhuman transmission has been observed,' Gu said. "It largely depends on how the virus further mutates."
Gregory Hartl, a spokesman for the World Health Organization, said the passing of the virus from mother to fetus was not really a case of human-to-human transmission as the two effectively function as a single body."
