The Centre for Health Protection (CHP) of the Department of Health urged members of the public to guard against dengue fever following the confirmation of two cases by laboratory test yesterday (August 10).
The first case involved a 21-year-old man living in Tseung Kwan O. He developed fever, muscle pain, and tiredness on July 30 and was admitted to Princess Margaret Hospital on August 4. He had recovered and was discharged on August 8.
His home contacts did not have any symptom of dengue fever.
CHP's investigations revealed that he had travelled to Indonesia with nine companions from July 6 to August 4. His companions did not have symptoms of dengue fever. This is classified as an imported case.
The second case involved a 57-year-old man living in Tuen Mun. He developed fever, headache and skin rash since July 31. He was admitted to Tuen Mun Hospital on August 4 and was discharged on August 9. His home contacts did not have any symptom of dengue fever.
He had travelled to Macau alone from July 23 to August 1. CHP is investigating the source of infection and has notified the Macau health authority about this case. This is classified as a case under investigation and its status will be reviewed after more information is collected.
Prior to these two new dengue fever cases, there have been a total of 19 imported cases of dengue fever so far this year. There were 31 cases in 2006 and all of them were classified as imported cases.
A spokesman for CHP urged members of the public to stay alert to the threat of dengue fever and help preventing 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.
