Hong Kong authorities have confirmed the first local case of dengue fever this year, involving a 58-year-old man living in Tai Wai in New Territories.
Dr Chuang Shuk-kwan, consultant for the Centre for Health Protection, said the agency is conducting an investigation into the case, Skypost reported.
The patient developed fever, headache, diarrhoea and skin rash since last Tuesday and had consulted private doctors and government hospitals, before blood tested positive for dengue fever antigen.
Residents at Tai Wai’s Grandway Garden public housing estate where the man lived were quoted as saying that scaffolding nets around the buildings may have something to do with the case.
Chuang warned that there could be up to 10,000 cases of dengue fever in Hong Kong if there is a big outbreak.
The health official noted that dengue fever cases have been on the rise recently in Kaohsiung in Taiwan and in Guandong province in mainland China.
Yuen Ming-chi, pest control officer at the Food and Environmental Hygiene Department, said the Ovitrap Index recorded in Tai Wai last month was among the top three among all local districts.
Ovitrap Index is a gauge of Aedes albopictus which causes dengue fever.
Sha Tin district councilor Lee Kam-ming said he has received complaints from residents of Grandway Garden since last month.
Lee suspects that large scaffolding nets around the building have been a breeding ground for mosquitoes.
Grandway Garden, built in 1990, had been at the center of a controversy related to a renovation project that was estimated to cost nearly HK$100 million.
