Chikungunya is a viral infection caused by the CHIK virus belonging to the Togaviridae family. The virus is transmitted through the bite of infected daytime biting female – primarily Aedes aegypti and Aedes albopictus – mosquitoes. They usually bite during the early morning and late afternoon, and are typically found in and around urban and suburban dwellings.

Thailand is the 1st country outside China to report novel coronavirus

In some cases, Chikungunya is asymptomatic – persons do not exhibit symptoms. Those with symptoms usually get ill 3-12 days after being bitten by an infected mosquito. Symptoms include sudden fever and severe muscle and joint pain. They can be accompanied by headache, fatigue nausea, vomiting, and a rash. Although most patients fully recover, chronic joint pain may last for several weeks or months. Other persistent problems may include eye, gastrointestinal, neurological, and heart complications. Persons with chronic health conditions, a weakened immune system, infants, and older persons are at risk of developing complications with this infection. Chikungunya is rarely fatal.
