|H7N9 case map.|
So that can be added to Shanghai, major markets in Hangzhou, Ningbo and Jinhua cities in Zhejiang (15), markets in Guangzhou, Guangdong ((3); plus a previous 2-week pause for disinfection in Shenzen (15) ), Hong Kong recently extended its ban (4) on live poultry imports from mainland China and Fujian provinces markets were closed fro disinfection back in 21-Jan.
No word, that I can find anyway, on market closures in the Jiangsu province (11.8% of all H7N9 cases), other sites in Fujian province (5.5%) or Anhui province (2.5% but over-represented in cases recently).
And yet with no cases announced yesterday - the latest in a recent precipitous decline in total human cases per day - it's tempting to wonder whether market shutdowns in regions that have had the highest case activity (Zhejiang and Guangdong provinces) and which produce or trade a lot of the nation's chickens, have had enough of a flow-on effect to stem the tide in other regions supplied by these.
Aside #1: Poultry eggs are mainly produced by >1-billion birds in Henan, Shandong, Hebei, Liaoning, Jiangsu, Sichuan, Hubei, Anhui, Heilongjiang and Jilin (7,8) whereas >4-billion broiler chickens (bred for meat) are more concetrated in Shandong, Jiangsu, Guangxi, Liaoning, Guangdong, Anhui, Sichuan and Henan provinces (2,6,8,9,10,11,12,13).
Aside #2: An interesting to read (5,9) that the volume of chicken consumed per capita has risen by 9-fold or more in recent years - it has not always been the staple but is part of the tradition.
