Abstract
A study was done on Chikungunya in the Kalpathy village, Palakkad which was moderately affected. The aim of the survey was to understand the nature and magnitude of the Chikungunya fever, the clinical signs and symptoms. A total number of 107 cases was surveyed door to door at six different localities in the Kalpathy village of the Palakkad district. The patient history, clinical signs and symptoms of the Chikungunya cases were recorded. The signs and symptoms recorded were fever, chills, arthalgia, eye pain, headache, edema, rash, oral ulcers, itch, myalgia, sore throat, distaste, nausea, vomiting, diarrhoea, neck pain, hypotension, dermatitis, dizziness and hyperpigmentation. The major symtopms were fever (100%), arthralgia (85.04%),vomiting (32.71%) edema (30.84%), myalgia (28.97%) and chills (28.03%). Significant differences were observed in the following symptoms, like eye pain (6.54%), back pain (20.56%), headache (19.62%), rash (13.08%), oral ulcer (1.82%), itch (14.01%), hyperpigmentation (1.89%), sore throat (9.34%), distaste (16.84%), backache (20.56%) diarrhoea (2.82%) and dizziness (3.73%). Chikungunya more severely affected the age group >35 years and the above mentioned symptoms were less commonly seen in the age group 6 months). .

Summary
Chickungunya is a viral disease caused by the alphavirus that is transmitted to humans by bite of infected Aedes aegypti mosquitoes. CHIKV is a member of the genus alpha virus, in the family Togaviridae. Chikungunya virus (CHIKV) was first isolated from the serum of a human in Tanzania in 1952 [1,2]. Chickungunya was first described by Marion Robinson and W.H.R. Lumsden in 1955, in Africa at Makonde Plateau an outbreak on the border between Tanzania and Mozambique, in 1952. According to Lumsden’s initial 1955 report, the term Chikungunyais derived from the Makonde root verb kungunyala, meaning to dry up or to become contorted. Robinson glossed the Makonde term as “that which bends up” [2]
