The disease is viral and is spread through mosquito bites. Symptoms include fever, headache, nausea, muscle and joint pain and minor bleeding. In severe cases, haemorrhage, organ failure and death can occur.
As there is currently no vaccine available to prevent dengue, prevention methods such as covering up and using insect repellant are key. Therefore, the CDC’s recommendation for healthcare practitioners is to advise patients travelling to destinations where there is a high risk of dengue to take measures to protect themselves from mosquito bites.
