Like many diseases Chikungunya virus infection plotted its name in history. The name of this disease may be new to many of us but Chikungunya virus was forts identified during an occurrence of dengue like illness in Tanzania in 1953.

The usual symptoms include fever and joint pain. Headache, muscle pain, rash, joint swelling may also occur. This infection is rarely fatal but the symptoms can be severe and cause disability of many patients. After treatment, within a week most patients may feel well again but some may have persisting joint pain for several months. This may be a risk factor for older adult patients of greater than 65 years, newborn infants if infected during birth and patents with medical conditions as hypertension and diabetes mostly.

The first incident was not like that it has not been occurred any more in between these long times. In the mean time this has numerous outbreaks documented in Africa and South-Asia.
