Chikungunya is a viral disease transmitted to humans by infected mosquitoes. It causes fever and severe joint pain, which is often debilitating. Other symptoms include muscle pain, headache, nausea, fatigue, and rash.
The disease shares some clinical signs with dengue and Zika, and can be misdiagnosed in areas where they are common. As there is no cure, treatment is focused on relieving the symptoms.
