Warning issued on dengue fever

People travelling to the Pacific Islands have been warned to guard against dengue fever.

Outbreaks of the disease in Tonga and New Caledonia have prompted the warning from the Auckland Regional Public Health Service.

Travellers and Pacific people visiting the islands are advised to take precautions to avoid mosquito bites.

Dengue fever is a serious viral disease spread by the bite of infected mosquitoes. There is no vaccine.

A sudden onset of a high fever and a severe headache are among its symptoms. Those affected could also get a skin rash and muscle and joint pain.

Symptoms usually start four to six days after being bitten by an infected mosquito but can appear from three to 14 days. Anyone returning from overseas with symptoms or feeling unwell should seek medical advice.

The disease can cause severe illness especially in people who have repeated infections.

It is important people who make repeat trips to dengue fever-infected areas understand the risk, the service says.

Public health doctor Dr Doone Winnard recommends people wear clothing that covers their arms and legs and apply insect repellent containing diethyl toluamide to both skin and clothing.

The outbreak in Tonga has mostly affected the main island of Tongatapu.

The service says so far this year 19 people have returned home with dengue fever acquired in Tonga. Sixteen were of Tongan ethnicity.

Only four people returned with the disease last year.
