Avian influenza A(H7N9)
The last H7N9 case was reported in February 2018 and no new cases have been reported since [Figure 1]. In total, 3 human cases of H7N9 have been reported to the World Health Organization (WHO) in wave 6 (October 2017 – September 2018). Cases in the 6th wave occurred in 3 out of 34 administrative regions across China [Figure 2], a drop from the 12-29 regions that reported cases in waves 1-5. This decrease in cases may be attributable to China’s new vaccine against both H5 and H7 in poultry, which was deployed after the number of illnesses caused in the 5th wave. A total of 1567 cases including at least 613 deaths have been reported globally since 2013. Two travel-related cases were reported in Canada in January 2015.
