HK CHP Notified Of 1 H7N9 Case In Mainland China (Yunnan Province)


Hong Kong's CHP today is reporting their notification of the first H7N9 case since September 15th, and the first of what is expected to be the 6th winter epidemic since the virus emerged in the spring of 2013. During China's 5th wave a record 766 cases were reported.

This first case comes from the prefecture-level city of Kunming, in Yunnan Province, roughly 150 miles from the Vietnamese border.  A bit surprising since temperatures there during the month of November were often above average (see chart below).

Today's CHP notification follows:

     The Centre for Health Protection (CHP) of the Department of Health is today (December 2) monitoring a notification from the National Health and Family Planning Commission that an additional human case of avian influenza A(H7N9) was recorded from November 24 to December 1 in Yunnan, and strongly urged the public to maintain strict personal, food and environmental hygiene both locally and during travel.

     The 64-year-old male patient in Kunming, known to have contact with dead poultry, had onset on November 21 and was in a serious condition.

     "This is the first human case reported in the Mainland since October 2017. As winter approaches, based on the seasonal pattern of avian influenza (H7N9) viruses, their activity in the Mainland is expected to increase," 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 CHP'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.

     The display of posters and broadcasting of health messages in departure and arrival halls as health education for travellers is under way. The travel industry and other stakeholders are regularly updated on the latest information.

     The public should maintain strict personal, hand, food and environmental hygiene and take heed of the advice below if handling poultry:

  • Avoid touching poultry, birds, animals or their droppings;
  • 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, 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.
