Chikungunya is a relatively rare viral fever that is caused by the bite of infected mosquitoes.  These mosquitoes can be found biting throughout daylight hours, though there may be peaks of activity in the early morning and late afternoon.  The incubation period is usually 1 to 12 days. This means the disease manifests 1 to 12 days after the bite of the mosquito. Chikungunya is sometimes mistaken for dengue which also manifests with similar symptoms.

Even though mortality rateof Chikungunya is less compared to dengue, symptoms last longer and affect the person. Most patients recover fully from Chikungunya virus infection. They get better after a few days, however sometimes joint pains can persist for a longer period after the other symptoms have disappeared.

Symptoms:

  • Abrupt onset of Fever with chills ( >104 F)
  • Headache
  • Joint Pain
  • Arthritis affecting multiple joints, can be debilitating
  • Swelling of joints
  • Sometime there may be infection of the conjunctiva of the eye
  • Nausea and vomitings
  • Bleeding, Rash may occur rarely

How to manage it:

  1. It is important to rule out dengue first by necessary investigations as the mortality rate is higher with dengue by employing some serological tests.
  2. Mainstay of treatment is relieving symptoms, supportive care and rest
  3. To relieve symptoms of fever and joint pain the drug commonly used is paracetamol.
