One of the frustrations with this year’s wave of H7N9 in China over the past two years has been the delays in reporting of cases by a number of Mainland provinces. We’ve looked at this issue several times, including in Jiangsu Province’s Uncertain H7N9 Count, and as a result the size and scope of this year’s outbreak is difficult to quantify.
Today Hong Kong’s CHP published their notification of 19 H7N9 cases, from 6 different provinces, going back more than six weeks. Individual case details, however, are not included.
Although we have seen several of these `bulk’ announcements this winter, there are still several provinces that have reported cases in previous years, but that we’ve not heard from this year (including Henan, Jilin, and Hebei).
The Centre for Health Protection (CHP) of the Department of Health (DH) today (March 9) received notification of 19 additional human cases of avian influenza A(H7N9) with the onset dates in the past five weeks prior to February 25 from the National Health and Family Planning Commission, and again urged the public to maintain strict personal, food and environmental hygiene both locally and during travel.
The patients comprise 13 males and six females aged from 3 to 76. Three of them (one man and two women) died and two (one man and one woman) were in critical condition. Eleven cases are from Zhejiang, three are from Jiangsu, two are from Hunan, one is from Fujian, one is from Guizhou and one is from Jiangxi.
To date, 618 human cases of avian influenza A(H7N9) have been reported by the Mainland health authorities in Guangdong (181 cases), Zhejiang (167 cases), Jiangsu (73 cases), Fujian (59 cases), Shanghai (45 cases), Hunan (26 cases), Anhui (24 cases), Xinjiang (10 cases), Jiangxi (10 cases), Shandong (six cases), Beijing (five cases), Henan (four cases), Guangxi (three cases), Jilin (two cases), Guizhou (two cases) and Hebei (one case).
