If history is any guide (see WHO Chart above), we ought to be getting near the start of H7N9's summer hiatus. The pattern has been - starting around epi week #20 and running through the heat of the summer - case reports drop off dramatically.
While this fourth winter wave has seen fewer cases reported than usual, we are still getting sporadic reports well towards the end of May.
On Sunday we saw Hebei Province report only their second case since the virus emerged in 2013, and today we have another case reported from Guangdong province.
There may be others we won't hear about until China releases their May infectious disease reports in mid-June.
This from Hong Kong's CHP.
CHP notified of additional human case of avian influenza A(H7N9) in Guangdong
The Centre for Health Protection (CHP) of the Department of Health (DH) today (May 26) received notification of an additional human case of avian influenza A(H7N9) from the Health and Family Planning Commission of Guangdong Province and again urged the public to maintain strict personal, food and environmental hygiene both locally and during travel.
The case involves a male patient aged 63 who lives in Meizhou, Guangdong.
From 2013 to date, 759 human cases of avian influenza A(H7N9) have been reported by the Mainland health authorities.
"We will remain vigilant and work closely with the World Health Organization and relevant health authorities to monitor the latest developments," a spokesman for the DH said.
The DH's Port Health Office conducts health surveillance measures at all boundary control points. Thermal imaging systems are in place for body temperature checks on inbound travellers. Suspected cases will be immediately referred to public hospitals for follow-up.
