What is Chikungunya virus?
Chikungunya virus is transmitted to humans by infected Aedes mosquitoes. Infected patients typically have a sudden onset high fever, incapacitating joint pain, muscle pain, headache, exhaustion, and a maculopapular rash that lasts 3 to 10 days. Chikungunya IgM test measures levels of IgM antibody against the Chikungunya virus and helps in the diagnosis of chikungunya infection during the acute phase of the disease (more than 5 days after symptom onset). Since the clinical signs and symptoms of this infection are similar to those of many other infectious diseases, including Dengue fever, doctors suggest using specific laboratory testing techniques to confirm the infection. The presence of Chikungunya IgM indicates current or recent infection.
