Chikungunya occurs in many tropical and subtropical regions, including parts of Asia, Africa and the Americas. In India, the disease is a public health concern, particularly in areas where mosquitoes that transmit the virus are present. Understanding chikungunya symptoms, transmission, diagnosis, treatment and prevention can help people recognize the illness and seek timely medical care.
Chikungunya spreads mainly through the bites of infected Aedes aegypti and Aedes albopictus mosquitoes. These mosquitoes can also transmit other viruses, including dengue. They commonly bite during the daytime, although biting activity may vary by location and conditions.
When a mosquito bites a person infected with chikungunya, it can acquire the virus. After the virus develops inside the mosquito, the mosquito may transmit the infection to another person through a subsequent bite. Chikungunya does not ordinarily spread through casual person-to-person contact, such as touching, hugging or sharing food.
Reducing mosquito exposure and preventing mosquito breeding are important ways to limit the spread of chikungunya.
