One more water sample preliminarily tests positive for Legionella pneumophila

     The Centre for Health Protection (CHP) of the Department of Health today (January 4) revealed that one more water sample taken from the office buildings in connection with a confirmed Legionnaires' Disease (LD) case involving a 67-year-old male patient has tested positive for Legionella pneumophila.

     The latest positive sample came from the private washroom of the Secretary for Home Affairs, located at 12/F, West Wing, Central Government Offices (CGO). The sample was collected before cleansing and disinfection measures were taken at CGO.

     A CHP spokesman said, "The result only became available today as it took time for the LD bacteria to grow in culture tests on the sample collected."

     Testing for the remaining water samples collected at various sites at CGO before thorough disinfection is still underway.

     The spokesman said that the present laboratory results are preliminary and final results are pending.

     The investigation is continuing.
