According to Dr Margaret Chan, Director-General of the World Health Organization in an address to the Executive Board today:
Since 2013, China has reported epidemics of H7N9 infections in humans, now amounting to more than 1000 cases, of which 38.5% were fatal.
The latest epidemic, which began in late September 2016, started earlier than usual, and since December has shown a sudden and steep increase in cases. In the most recent two clusters, WHO could not rule out limited human-to-human transmission, though no sustained transmission has been detected to date.
The 60 male and 24 female patients aged from 3 to 79 had their onset from December 13, 2016 to January 13, 2017. The cases were from Jiangsu (34 cases), Zhejiang (23 cases), Anhui (14 cases), Fujian (five cases) and four cases each in Hunan and Jiangxi. Among them, 28 reported exposure to poultry or poultry markets while the source of infection of 52 cases was still under investigation.
Since November 2016, the Mainland health authorities have already recorded 215 human H7N9 cases to date.
