Overview

Chikungunya virus is primarily transmitted to humans through the bites of infected mosquitoes, predominantly Aedes aegypti and Aedes albopictus.
Humans are the primary host of chikungunya virus during epidemic periods.
Blood-borne transmission is possible; cases have been documented among laboratory personnel handling infected blood and a health care worker drawing blood from an infected patient.
Rare in utero transmission has been documented mostly during the second trimester.
Intrapartum transmission has also been documented when the mother was viremic around the time of delivery.
Studies have not found chikungunya virus in breast milk.
The risk of a person transmitting the virus to a biting mosquito or through blood is highest when the patient is viremic during the first week of illness.
