Dengue fever

Dengue fever is a viral infection that causes a severe flu-like illness. It is commonly found in more than 100 countries worldwide and can occur in both rural and urban areas. About half of the world’s population is thought to live in areas with a risk of dengue fever.
  • Symptoms Fever, intense headache, eye pain, joint pains and a rash.
  • How do you catch dengue fever? Dengue fever is transmitted by a mosquito that mainly bites during the daytime.
  • Incubation period usually 4 – 7 days
  • Diagnosis Diagnosis is usually based on the symptoms and confirmed by blood tests.

Prevention

Dengue fever is prevented by avoiding mosquito bites, through use of an effective insect repellent and wearing long, loose-fitting clothing.

Treatment

There is no cure, so treatment consists of nursing care, pain killers and management of any complications.

  • There is no vaccine available to protect travellers
  • Severe cases can be fatal - but this is very rare in travellers
  • Approximately 75% of infections are free of symptoms, so are not obvious
