MedlinePlus has published a new health topic page on chikungunya virus.
“Chikungunya is a virus that spread by the same kinds of mosquitoes that spread dengue and Zika virus. Rarely, it can spread from mother to newborn around the time of birth. It may also possibly spread through infected blood. There have been outbreaks of chikungunya virus in Africa, Asia, Europe, the Indian and Pacific Oceans, the Caribbean, and Central and South America.”
