For the 5th time this fall, and the 3rd time this November, we’ve a report of a human infection from the emerging H7N9 avian virus in China. Although the number of cases this fall thus far pales when compared to last spring, they do show that the virus continues to circulate widely in the Eastern provinces of that country.
While it is probable that there may be more mild or asymptomatic cases not being picked up by Chinese surveillance, so far we have not seen evidence of sustained human-to-human transmission of this virus.
Nevertheless, no one from the Chinese CDC (see Chinese CDC: Be Alert For H7N9), to Hong Kong’s CHP (see Dr. Ko Wing-man: Joint Measures To Control H7N9, to our own CDC (see CDC: H7N9 Update) is taking this viral threat lightly.
