Stay alert to threat of Dengue fever

The department called on the public to stay alert to the threat of Dengue fever.

To avoid mosquito bites:

* 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 over 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.
