GloPID-R report on chikungunya, o’nyong-nyong and Mayaro virus, part 5: Entomological aspects

This report, the most recently published in Antiviral Research by the GloPID-R chikungunya (CHIKV), o’nyong-nyong (ONNV) and Mayaro virus (MAYV) Working Group, is dedicated to the entomological aspects of CHIKV, ONNV and MAYV.

The authors focused on the transmission cycle and natural vectors that sustain circulation of these viruses in their respective locations.

The chikungunya virus has expanded globally through transmission in urban settings using vectors such as Aedes albopictus and Aedes aegypti. However, currently, ONNV is confined to Africa and MAYV to central-southern America.

Knowledge of the natural ecology of transmission and the capacity of different vectors to transmit these viruses is crucial to understand CHIKV emergence, and to assess the risk that MAYV and ONNV will expand on a wide scale using anthropophilic mosquito species not normally considered primary vectors.

In the report, the experts identify knowledge gaps and provide adapted recommendations to address future entomological investigations.

This report is based on the work of scientific experts from the GloPID-R Chikungunya working group, chaired by Xavier de Lamballerie (Aix-Marseille University), which was specifically established to identify research gaps and make recommendations on research priorities for the CHIKV, ONNV, and MAYV viruses. The working group focuses on the natural history, epidemiology, and medical management of infections caused by these viruses. The goal is to improve individual patient care and outbreak management.
