Ten days ago, we saw the first report that China's H7N9 epidemic had moved into their Xizang Autonomous Region (seeTibet Autonomous Region Statement On Their 1st H7N9 Case) with the announcement that a poultry seller in Lhasa had tested positive.
Last Friday, the NHFPC notified Hong Kong of two additional cases in Xizang, albeit with no details. My attempts on Friday to get more information from the Tibet Autonomous Region Health & Family Planning Commission website - which was easily reachable last week - failed, with their website repeatedly timing out.
After several attempts this morning, I had better luck and retrieved a statement (see below) which indicates two additional poultry sellers from the same market developed fever and flu-like symptoms around the same time as the first case. While both tested negative when first hospitalized - a week later both tested positive for the virus.Health authorities are attributing this three-person cluster to a shared common exposure to infected poultry - not to human-to-human transmission.
As we’ve discussed previously, when it comes to proving human-to-human (H-2-H) transmission of an emerging virus, the bar is set pretty high. When there are other, equally plausible explanations (e.g. shared environmental exposures), then H-2-H cannot be assumed.Lhasa two cases of new H7N9 cases
