Vector – Aedes albopictus
Aedes albopictus is opportunistic in its choice of larval habitats, inhabiting both artificial containers (e.g., waste tires, flowerpots, gutters, trash cans) and natural containers (e.g., leaf axils, tree holes). Oviposition takes place just above water level. Females are aggressive biters. The other key vector for CHIKV is Aedes aegypti.
Pathogen
Chikungunya virus (CHIKV) is an insect-borne virus of the genus Alphavirus. CHIKV infection causes an illness with symptoms similar to dengue fever.
The initial phase of the disease, which lasts 2–5 days and then ends abruptly, can include fever, rash on the trunk or limbs, and pain affecting multiple joints. The joint pain, however, lasts for much longer — in some cases for years, depending on the patient’s age.
