Chikungunya is an arboviral disease transmitted by aedes mosquitoes. The virus was first isolated in 1953 in Tanzania. Chikungunya virus is a member of the genus Alphavirus and the family Togaviridae. ⋯ In the ongoing Indian outbreak, in which Aedes aegypti is the presumed vector, 1 400 000 cases of chikungunya were reported during 2006. The reasons for the re-emergence of chikungunya on the Indian subcontinent, and for its unprecedented incidence rate in the Indian Ocean region, are unclear. Plausible explanations include increased tourism, chikungunya virus introduction into a naive population, and viral mutation.

Sepsis, an infection-induced inflammatory syndrome, is a leading and increasing cause of mortality worldwide. Animal and human observational studies suggest statins may prevent the morbidity and mortality associated with the sepsis syndrome. ⋯ Since statins do not target individual inflammatory mediators, but possibly reduce the overall magnitude of the systemic response, this effect could prove an important distinguishing feature modulating the host response to septic insults. This work establishes the biological plausibility needed for future trials of statins in critical illness.
