A destructive arthropathy following Chikungunya virus arthritis--a possible association.

Chikungunya virus arthritis is an acute severe polyarthritis following upon the bite of infected mosquitoes in endemic areas. With rapid air transport an increasing number of tourists are being exposed to potential infection. Whether tourists returning home in the incubation viremic stage can infect local mosquito populations in their home countries is unknown. Most cases recover from the severe joint pains within several weeks but up to 12% retain some residual joint symptoms for years. A case report is given of probable Chikungunya arthritis progressing to joint destruction before ultimately subsiding after 15 years leaving a sequela of destroyed metatarsal heads and late osteoarthritic changes in the ankles.
