Hong Kong to Trial Bacteria-Infected Male Mosquitoes to Combat Dengue
Strategy follows city's first local dengue fever case in over a year; infected males will prevent offspring from maturing
Auf einen Blick
- Hong Kong will trial a 'mosquito-to-control-mosquito' strategy next year, infecting male mosquitoes with bacteria to prevent their offspring from reaching maturity.
- The initiative follows the city's first locally recorded dengue fever case since 2024, involving a 21-year-old man bitten near a construction site in Penny's Bay on Lantau Island.
- The Director of Food and Environmental Hygiene announced the government may lower the threshold for stepping up mosquito control as the mosquito population rises rapidly.

Warum es wichtig ist
Hong Kong recorded its first local dengue fever case since 2024, involving a 21-year-old man who was bitten by mosquitoes near a road construction site in Penny's Bay on Lantau Island. The city's mosquito population has risen more rapidly this month, prompting authorities to consider enhanced control measures.
Hong Kong will trial a "mosquito-to-control-mosquito" strategy next year, under which the insect males are infected with bacteria to prevent their offspring from reaching maturity, following the city's first local dengue fever case in over a year. Announcing the strategy on Sunday, Director of Food and Environmental Hygiene Donald Ng Man-kit said the government would consider stepping up mosquito control measures with a lower threshold, as the city's mosquito population rose more rapidly this month. The first locally recorded dengue fever case since 2024 was reported last week, involving a 21-year-old man who was bitten by mosquitoes near a road construction site in Penny's Bay on Lantau Island. Authorities have carried out mosquito control and other preventive measures at the site and in the surrounding area. Explaining the plan in a televised interview, Ng said that by infecting the males with a designated bacterium, any offspring produced after mating would fail to reach maturity. He added that the strategy is expected to reduce the overall mosquito population.
