The Centre for Health Protection (CHP) of the Department of Health today (February 25) received notification from the National Health and Family Planning Commission that 28 additional human cases of avian influenza A(H7N9), including four deaths, were recorded from February 13 to 23. The CHP strongly urges the public to maintain strict personal, food and environmental hygiene both locally and during travel.

      The 22 male and six female patients aged from four to 81 had their onset from January 27 to February 17. The cases were from Anhui (five cases), Guangdong (five cases), Jiangsu (four cases), Zhejiang (four cases), Henan (three cases), Hunan (two cases), Jiangxi (two cases), and one case each in Fujian, Hubei and Shandong. Among them, 17 reported exposure to poultry or poultry markets.

     In addition, the CHP is closely monitoring one additional human H7N9 case reported in Guangxi. According to the Health and Family Planning Commission of Guangxi Zhuang Autonomous Region, a patient in Pingle County with exposure to poultry has died.

     There is a likely risk that environments with live poultry in the Mainland might be contaminated with avian influenza viruses. Travellers to the Mainland or other affected areas must avoid visiting wet markets, poultry markets or farms. They should be alert to the presence of backyard poultry when visiting relatives and friends. They should also avoid purchase of 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. 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 while 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 them 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.

     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.
