Hong Kong's Center for Health Protection (CHP) were notified of three additional cases of avian influenza (H7N9) in the Mainland and have issued a warning to the public to maintain strict personal, food, and environmental hygiene locally and while traveling.

Those affected include a 61-year-old man in Jiangsu who had poultry exposure, a 54-year-old woman in Anhul with no poultry exposure, and a 52-year-old man who worked in a market in Zhejiang.  The market worker died, and the remaining two patients are listed in serious condition.

From 2013 to date, 770 human cases of avian influenza A(H7N9) have been reported by the Mainland health authorities, while since October 2015 to date, 113 have been recorded.

Suspected cases are immediately referred to public hospitals for checkups. The display of posters and broadcasting of health messages is underway.

The public is advised to remain vigilant and take heed of the following advice against avian influenza: Do not visit live poultry markets and farms; avoid contact with poultry, birds and their droppings; if contact has been made, thoroughly wash hands with soap; avoid entering areas where poultry may be slaughtered and contact with surfaces which might be contaminated by droppings of poultry or other animals; poultry and eggs should be thoroughly cooked before eating; wash hands frequently with soap, especially before touching the mouth, nose or eyes, handling food or eating, after going to the toilet, or touching public installations or equipment (including escalator handrails, elevator control panels and door knobs), and when hands are dirtied by respiratory secretions after coughing or sneezing; cover the nose and mouth while sneezing or coughing, hold the spit with a tissue and put it into a covered dustbin; avoid crowded places and contact with fever patients; and wear masks when respiratory symptoms develop or when taking care of fever patients.
