Overview
Chikungunya is a relatively rare form of viral fever caused by an alphavirus that is spread by mosquito bites from Aedes aegypti mosquitoes, though recent research by the Pasteur Institute in Paris claims the virus has suffered a mutation that enables it to be transmitted by Aedes albopictus (Tiger mosquito).[1] This was the cause of the plague in the Indian Ocean and a threat to the Mediterranean coast at present, requiring urgent meetings of health officials in the region.
Historical Perspective
The name chikungunya is derived from the Makonde word meaning "that which bends up" in reference to the stooped posture developed as a result of the arthritic symptoms of the disease. The disease was first described by Marion Robinson in 1955, following an outbreak on the Makonde Plateau, along the border between Tanganyika and Mozambique, in 1952. Chikungunya is closely related to O'nyong'nyong virus.
Epidemiology and Demographics
Chikungunya was first described in Tanzania, Africa in 1952. The first outbreak in India was in 1963 in Kolkata(Calcutta). An outbreak of chikungunya was also discovered in Port Klang in Malaysia in 1999 affecting 27 people [2] [3]. There was an outbreak in Italy late 2007, with 160 cases.
Diagnosis
Symptoms
The common symptoms of Chikungunya include fever, petechial or maculopapular rash and arthralgia or arthritis affecting multiple joints.
Treatment
Prevention
The most effective means of prevention are those that protect against any contact with the disease-carrying mosquitos. These include using insect repellent containing NNDB, DEET or permethrin, wearing long sleeves and trousers (pants), and securing screens on windows and doors. It's also important to empty stagnant water where mosquitoes breed.
