Since we were already aware of three H7N9 cases earlier in the fall (in October and November), it isn’t entirely clear how many of those cases are included in today’s report citing 8 cases, and 4 deaths over the past 2 months.
Based on Jiangsu Province’s December Infectious disease report – which lists 4 H7N9 cases during that month – it seems likely that at least 4 or possibly 5 of these cases were previously unreported.
Without onset dates, ages, and genders it becomes increasingly difficult to keep any sort of reasonable count of cases. Previously Hong Kong’s CHP has been notified of cases by the mainland, and has promptly published those announcements, but we’ve not seen any published accounts of these cases on their website either.
As I wrote earlier today, in Fujian Province Reports 6 H7N9 Cases In December, the lack of timely and robust reporting of cases would greatly diminish our ability to evaluate this year’s epidemic wave. We obviously never know with precision how many infections occur – as many will be too mild to seek medical care – but knowing the number of severe cases (and their outcomes) provides a pretty good snapshot of the epidemic.
About all we can say at this point is – with the addition of at least 10 more cases in the month of December – is that the H7N9 season is apparently off to a strong start.
