Health minister Dr. Ko Wing-man has called for stepped-up mosquito control measures in all districts after a 59-year-old Hong Kong woman was diagnosed with dengue fever, the fourth local case reported this year.
Ko said health officials are very concerned about the situation.
“In the past few years, the number of dengue fever cases in Hong Kong was more or less around a hundred per year and most of these cases were imported,” he said.
“Each year, we only have one, two or three local cases but we have four local cases so far this year.”
The latest case, confirmed on Monday, lives in Tin Ma Court in Wong Tai Sin, but the three earlier cases came from the Central/Mid-Levels area, according to the health department’s Centre for Health Protection (CHP).
“Further genetic analysis reveals that her blood specimen tested positive for serotype 1 dengue virus … different from serotype 3 of the three local cases earlier,” a CHP spokesman said.
As part of efforts to control a possible spread, health officials have conducted a site visit and field investigations at Tin Ma Court, conducting interviews and questionnaire surveys among residents, but so far the results were negative.
The CHP, in cooperation with the Food and Environmental Hygiene Department, also gave tips to members of the public, especially residents and workers in Central and Wong Tai Sin, on how to prevent the spread of the disease.
It urged the public to:
- Inspect the household or workplace to check for potential mosquito breeding sites and remove them. Leave no stagnant water;
- Apply DEET-containing insect repellents to exposed parts of the body and clothing; and
- If fever, rash, pain behind the eyes or muscle or joint pain develop, seek medical attention early.
