|H7N9 Epidemic Waves - FAO June 7th Update|
After two weekly reports (#21 & #22) with just 9 new H7N9 cases each, this week we see an increase to 12 infections reported from China's Mainland's.
Normally, by late spring or early summer, China's H7N9 winter epidemic had pretty much run its course. But yesterday the NHFPC Announced 72 H7N9 Cases (37 Deaths) For The Month Of May - a roughly 5-fold increase over any previous May report.
While we have seen a dramatic reduction in case reports compared to what we saw last winter, H7N9 continues to hang on, particularly in the northern provinces of China.
Today Hong Kong's CHP has released their week 23 Avian Influenza report which details the 12 cases announced last Friday by China's NHFPC, which brings the number of cases reported by the Mainland during this 5th epidemic wave to 727.
Eight of the 12 cases are male, and a bit unusually, there are two pediatric cases, one mild (age 4) and the other in serious condition (age 16). Despite the recent increase in fatal cases, no fatalities are announced in this week's group.
