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 flowerpots;

* 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 a trip should consult a doctor as soon as possible and provide details of their travel.
