There is concern that another human-to-human infection of H5N1 has occured in China. The son, aged 24, died last week. His father is now in hospital with confirmed H5N1. Earlier, the Chinese government reported that there was no known contact between the index case (son) and either poultry or wild birds. It is unknown if the dead young man frequented poultry "wet markets" where he would purchase poultry and then have it prepared for cooking.
The son developed symptoms in late November; the father, in early December. This fits the profile for human-to-human transmission timeframes, with an incubation period of several days before onset of symptoms.
Watch this blog, plus Crawford Kilian's H5N1, Mike Coston's Avian Flu Diary, FluWiki and FluTrackers, and the other sites in the links frame on the left side of the page, as events progress. Not good news.
