An imported case of dengue fever

3 Jul 2008

The Centre for Health Protection (CHP) of the Department of Health today (July 3) urged members of the public to guard against dengue fever following the confirmation of an imported case by laboratory test.

The case involved a 37-year-old woman who came to Hong Kong on June 19. She developed symptoms of dengue fever including fever, chills, muscle pain and rash on June 22 and was admitted to Kwong Wah Hospital on June 26. She was discharged on June 30.

CHP's investigation revealed that her home contacts did not have any symptom of dengue fever.

Sixteen cases of imported dengue fever have been reported to the CHP so far this year. Fifty-eight cases were reported in 2007 and all of them are classified as imported cases.

A spokesman for CHP urged the public to stay alert to the threat of dengue fever and to help prevent mosquito breeding by taking the following measures:

* Put all used cans and bottles into dustbins with covers;
* Change water for plants at least once a week, leaving no water in the saucers underneath flower pots;
* Cover tightly all water containers, wells and water storage tanks, and
* Keep all drains free from blockage.

Travellers should take the following preventive measures:

* Wear long-sleeved tops and trousers;
* Use insect repellent on the exposed parts of the body, and
* Use mosquito screens or nets when rooms are not air-conditioned.

Anyone feeling unwell after returning from their trip should consult a doctor as soon as possible and provide details of their travel to the doctor.
