For the second day in a row Mainland China is reporting another human H5N6 infection, this time in Guangdong Province. This is the 16th case reported out of China since last December, and represents a sudden, and marked, increase in case reports.
Details beyond the patient's age, gender, and location are lacking in this report. This uptick is also unusual as it has continued throughout the summer.
First the report from Hong Kong's CHP, then I'll have a brief postscript.
CHP closely monitors human case of avian influenza A(H5N6) in Mainland
The Centre for Health Protection (CHP) of the Department of Health is today (August 20) closely monitoring a human case of avian influenza A(H5N6) in the Mainland involving a 52-year-old woman living in Huizhou, Guangdong Province, and again urged the public to maintain strict personal, food and environmental hygiene both locally and during travel.
From 2014 to date, 40 human cases of avian influenza A(H5N6) have been reported by Mainland health authorities.
"All novel influenza A infections, including H5N6, are notifiable infectious diseases in Hong Kong," a spokesman for the CHP said.
Travellers to the Mainland or other affected areas must avoid visiting wet markets, live poultry markets or farms. They should be alert to the presence of backyard poultry when visiting relatives and friends. They should also avoid purchasing live or freshly slaughtered poultry, and avoid touching poultry/birds or their droppings. They should strictly observe personal and hand hygiene when visiting any place with live poultry.
Travellers returning from affected areas should consult a doctor promptly if symptoms develop, and inform the doctor of their travel history for prompt diagnosis and treatment of potential diseases. It is essential to tell the doctor if they have seen any live poultry during travel, which may imply possible exposure to contaminated environments. This will enable the doctor to assess the possibility of avian influenza and arrange necessary investigations and appropriate treatment in a timely manner.
While local surveillance, prevention and control measures are in place, the CHP will remain vigilant and work closely with the World Health Organization and relevant health authorities to monitor the latest developments.
The public should maintain strict personal, hand, food and environmental hygiene and take heed of the advice below when handling poultry:
Avoid touching poultry, birds, animals or their droppings;The public may visit the CHP's pages for more information: the avian influenza page, the weekly Avian Influenza Report, global statistics and affected areas of avian influenza, the Facebook Page and the YouTube Channel.
- When buying live chickens, do not touch them and their droppings. Do not blow at their bottoms. Wash eggs with detergent if soiled with faecal matter and cook and consume the eggs immediately. Always wash hands thoroughly with soap and water after handling chickens and eggs;
- Eggs should be cooked well until the white and yolk become firm. Do not eat raw eggs or dip cooked food into any sauce with raw eggs. Poultry should be cooked thoroughly. If there is pinkish juice running from the cooked poultry or the middle part of its bone is still red, the poultry should be cooked again until fully done;
- Wash hands frequently, especially before touching the mouth, nose or eyes, before handling food or eating, and after going to the toilet or touching public installations or equipment, such as escalator handrails, elevator control panels or door knobs, or when hands are dirtied by respiratory secretions after coughing or sneezing; and
- Wear a mask if fever or respiratory symptoms develop, when going to a hospital or clinic, or while taking care of patients with fever or respiratory symptoms.

With mounting fears that H7N9 was creeping ever closer to becoming a pandemic strain, less than a month later the MOA Ordered HPAI H7N9 Vaccine Deployed Nationwide by the fall.
Although previous poultry vaccination programs had yielded varying levels of success, China's dramatic drop in human infections, outbreaks in poultry, and virus detection from routine surveillance over the next 3 years was nothing less than remarkable.
While H7N9 remains subdued, HPAI H5N6 appears to be mounting a comeback. Since we aren't seeing reports of concurrent outbreaks in poultry, the virus may be spreading silently in poultry.
When H5N6 infects humans, it tends to produce serious illness, and fatal outcomes are common. So far, human infections have not been reported outside of China, Vietnam, and Laos.
But the concern remains that H5N6 - very much like H5N1 and H5N8 - could someday expand its range, thereby increasing its impact both on poultry interests, and potentially, on public health.
Stay tuned.
