A 24-year-old woman, who travelled to a Southeast Asian country on January 25, has been confirmed to have contracted Dengue fever.

This brings the total number of Dengue cases this year to eight - all imported.

The woman developed a fever and dizziness on February 14, and returned to Hong Kong two days later.

She was admitted to Prince of Wales Hospital and was later discharged after recovery.

The Department of Health called on the public to stay alert and take precautionary measures to avoid mosquito bites.

People should:

* put all used cans and bottles into covered dustbins;

* 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:

* wear long-sleeved tops and trousers;

* use insect repellent over exposed parts of the body; and,

* use mosquito screens or nets when rooms are not air-conditioned.
