The symptoms of Chikungunya appear 4 to 7 days after the bite of the contaminated mosquito.
Chikungunya affects children and adults. Most often, the infected person has a high fever and joint pain (arthralgia) intense especially in the small joints of the hands and feet. These inflammatory pains can be severe and prolonged.
These painful symptoms are often accompanied by muscular pains (like aches and pains), headaches, even rashes that sometimes scratch.
In young children, the fever can be very high, and exceed 40 ° C. And thus cause a risk of convulsions.
Rarely, the disease is severe with the occurrence of haemorrhagic or neurological symptoms. Serious cases of hepatitis, encephalitis and shocks have been reported in recent epidemics. Encephalitis (inflammation of the brain) has also been observed in neonates of infected mothers at the time of delivery.
The Chikungunya virus, like all infectious diseases, can aggravate the health of fragile, elderly or already sick people (heart failure, diabetics, alcoholics, etc.).
In general, the patient heals in a few days. However, residual symptoms (fatigue and joint pain) may persist for several weeks. These chronic forms of Chikungunya can even be very debilitating.
