DH announces latest situation regarding Legionnaires’ disease cases The CHP is conducting epidemiological investigations to identify the potential sources of infection and high-risk exposure. An initial investigation revealed that the seven community-acquired cases are sporadic cases. No epidemiological linkages have been established between these cases and other confirmed cases previously recorded in Hong Kong.
As of July 4, 89 LD cases had been recorded this year. In 2025 and 2024, there were 167 and 135 LD cases respectively.
Men, people aged over 50, smokers, alcoholics and persons with weakened immunity are more susceptible to LD. Some situations may also increase the risk of infection, including poor maintenance of water systems; living in areas with old water systems, cooling towers or fountains; using electric water heaters, whirlpool spas or hot water spring spas; and recent stays in hotels or ships.
