Health officials in Hong Kong have put 19 people under quarantine because they were in contact with an 80-year-old man sickened by avian influenza. The victim is the second human to be infected with H7N9 avian influenza in Hong Kong.

According to a statement from the Centre for Health Protection's Department of Health, the man lives in Shenzhen and was admitted to a hospital on November 13. Among the people who had contact with the patient are family members, a cab driver and other patients at the Tuen Mun Hospital, where the avian influenza patient has been treated, according to a Bloomberg report.


It is not yet known whether the man had contact with live poultry to catch the H7N9 avian influenza virus.

Hong Kong's first case of H7N9 avian influenza was reported in early December. The first of the two Hong Kong avian influenza patients was a 36-year-old woman.
