Legionella detected at Kai Ching Estate

July 13, 2015

Disinfection measures will be conducted throughout Kai Ching Estate after Legionella bacteria was detected in Mun Ching House.


Centre for Health Protection Surveillance & Epidemiology Branch Head Dr Regina Ching told the media today a 72-year-old man with chronic illness was admitted to Prince of Wales Hospital on May 28.


He was treated and then discharged on June 12. However, water samples from his home tested positive for Legionella pneumophila.


Centre for Health Protection officers changed the faucets in his home, but the bacteria was still detected in another batch of water samples collected on July 6.


The bacteria was also detected in samples collected from another flat on the same floor, and a water supply outlet on the first floor of the building.


The centre has informed the Housing Department of the issue and disinfection will be conducted in all six of the estate's buildings.


Dr Ching advised residents to avoid using misting devices, including shower heads, to prevent transmission, and tap water should be boiled before drinking.
