The best way to avoid infection is to prevent mosquito bites. The mosquitoes that transmit dengue bite during the day, from dawn until dusk. During these hours your skin should be covered up with long, loose fitting clothing. Insect repellent should be applied to any exposed areas of skin, and reapplied as suggested by the manufacturer’s instructions.

Most dengue infections produce no symptoms, or result in mild symptoms only. Between 4-10 days after the mosquito bites, a sudden onset of fever, headache, muscle and joint pains may occur. A rash may also develop. The illness usually gets better within a few days to a week, and serious complications are uncommon. In 1–2% of cases, dengue can progress to a more serious illness, called severe dengue, which can be fatal.
