Chikungunya: Causes, symptoms and prevention measures





Introduction
Chikungunya is a mosquito-borne viral disease describes the stunted form of people suffering from joint pain (arthralgia). Chikungunya is characterized by sudden onset of fever causing joint pain.

Causes
Chikungunya occurs in humans by the bite of infected female mosquitoes. Typically, the mosquitoes involved are Aedes aegypti and Aedes albopictus, two species that can transmit other mosquito-borne viruses including dengue. These mosquitoes can be found biting during the daylight hours, although activity peaks may occur in the early morning and afternoon.

Symptoms
Common signs and symptoms include muscle aches, headaches, nausea, fatigue, and rash. Joint pain is often very weak, but usually lasts for a few days or maybe prolonged for weeks, but in some cases, joint pain may persist for several months or years.


Diagnostic techniques
Several methods can be used for diagnosis. Serological tests, such as enzyme-linked immunosorbent assay (ELISA), can confirm the presence of IgM and IgG anti-chikungunya antibodies. The samples collected during the first week after the onset of symptoms should be tested by serological and virological methods (RT-PCR).

Treatment is primarily directed at relieving symptoms, including antipyretics, optimal analgesics, and joint pain using fluids. There is no commercial chikungunya vaccine.

Prevention techniques

Prevention methods include:
Reducing the number of container habitats filled with natural and artificial waters that support breeding of mosquitoes.
During an outbreak, insecticides can be sprayed to kill flying mosquitoes.
Clothing that reduces skin exposure. Repellents can be applied inside the skin or on clothing according to product label instructions.
Mosquito coils or other pesticide vaporizers can also reduce indoor bites.
