The Centre for Health Protection (CHP) of the Department of Health in Hong Kong released the latest news yesterday regarding an epidemiological investigation of a case of Legionnaires’ disease in Hong Kong that was first reported on April 21.
The 60-year-old man was admitted to Hong Kong Baptist Hospital (HKBH) on April 5 regarding a different health issue and began to develop symptoms consistent with Legionnaires’ disease on April 15. He was transferred to a private hospital on April 20 and then was moved to the Intensive Care Unit a few days later on April 23, but is now in stable condition.
According to the report, the man had no travel history within the incubation period.
“In relation to investigation for the possible source of infection, water and environment samples were collected from HKBH and his residence for testing of Legionella, the bacteria causing LD, during our joint epidemiological and environment investigations with the Electrical and Mechanical Services Department (EMSD). The CHP again conducted a site visit to HKBH today and advised on the disinfection of the relevant water system. As precautionary measures, the CHP has recommended HKBH to install filters to the shower heads of the affected ward, and to provide boiled water for in-patients’ drinking and mouth rinsing as infection control,” a spokesman for the CHP said.
Multiple samples taken at HKBH tested positive for Legionella pneumphila serogroup 1, and all samples taken at the patient’s home came back negative.
The investigation is still ongoing.
