What is Chikungunya fever?

Chikungunya fever is a mosquito-borne disease caused by the Chikungunya virus, primarily transmitted through the bite of infected Aedes mosquitoes.

Symptoms to watch for

The incubation period for Chikungunya fever ranges from one to 12 days, with symptoms typically emerging three to seven days after infection. The illness often strikes suddenly, bringing on high fever with chills, severe joint pain, rash, headaches, muscle aches, fatigue, nausea, vomiting, and conjunctivitis (red eyes).

Since symptoms resemble dengue fever and other mosquito-borne illnesses, anyone with recent mosquito exposure or travel history to affected areas should seek medical attention promptly.

Currently, there is no specific antiviral treatment or widely available vaccine for Chikungunya fever. Prevention depends on avoiding mosquito bites and eliminating their breeding sites.

1. Personal protection against mosquito bites

  • Use insect repellent containing DEET or Picaridin on exposed skin and clothing.
  • Wear long-sleeved, light-colored clothing to reduce skin exposure, especially during peak mosquito activity at dawn and dusk.
  • Install window and door screens to keep mosquitoes out, and use mosquito nets while sleeping.
  • Use air conditioning when possible, as mosquitoes are less active in cooler environments.

2. Eliminate mosquito breeding sites

  • Remove standing water from flower pots, buckets, tires, and other containers where mosquitoes lay eggs.
  • Use larvicides in stagnant water environments, such as fountains and drains.
  • Keep your surroundings clean and dry, as mosquitoes thrive in damp, shaded areas.
  • Regularly dry clothes and bedding to reduce moisture that attracts mosquitoes.

3. Travel precautions

  • Check travel advisories before visiting high-risk regions such as Southeast Asia and Africa.
  • Monitor your health for 14 days after returning and seek medical help immediately if symptoms develop.
