Influenza A(H7N9) - China - Monitoring human cases Opening date: 31 March 2013 Latest update: 4 September 2014 Update of the week
In March 2013, a novel avian influenza A(H7N9) virus was detected in patients in China.
Since then, 453 cases have been reported, including 175 deaths.
No autochthonous cases have been reported from outside of China. Most cases have been unlinked, and sporadic zoonotic transmission from poultry to humans is the most likely explanation for the outbreak.
Sustained person-to-person transmission has not been documented and transmission peaked during the winter of 2013-2014. The reason for this pattern is not obvious. Since October 2013, 318 cases have been reported, the majority from previously affected provinces or in patients who visited these provinces prior to onset of illness.
Since the last monthly update on 6 August 2014, two new cases of A(H7N9) have been reported. A 66-year-old female, who has since passed away, and a 53-year-old male, both from a previously unaffected area of Xinjiang Uygur Autonomous Region.
Epidemiological summary
In March 2013, a novel avian influenza A(H7N9) virus was detected in patients in China. Since then, human cases have continued to be reported, and as of 4 September 2014, there were 453 laboratory-confirmed cases:
Zhejiang (139),
Guangdong (109),
Jiangsu (56),
Shanghai (42),
Fujian (22),
Hunan (24),
Anhui (18),
Jiangxi (6),
Henan (4),
Beijing (4),
Guangxi (4),
Shandong (4),
Hebei (1),
Guizhou (1),
Jilin (2),
Xinjiang Uygur (2),
Hong Kong (10),
Taiwan (4) and one imported case in Malaysia.
In addition, there was one case in Malaysia and one fatal case in Canada, both exported from China.
The second wave of the outbreak started in October 2013.
Since then 318 cases have occurred. The number of reported cases has been declining since April 2014 and only sporadic cases have been reported during the past months.
Most cases have developed severe respiratory disease. One hundred and seventy-five patients have died.
Is that a typo for Canada (H5N1?) and is there a 2nd case in Malaysia (MERS?) or is it really H7N9 ???????????
That is a very high fatal case count of 175!
Some further clarification from ECDC would be helpful!
My last numbers from the Mainland China MOH is 436 at least 157 fatal cases ...pending the recent two cases and 1 death!
