The mosquito-borne Chikungunya virus, already rampant in Jamaica, has spread to the Cayman Islands and other parts of the Caribbean.

The Caribbean Public Health Agency’s latest report, dated October 20, states that there were 59 confirmed cases of chikungunya in Jamaica, but medical professionals are saying that the prevalence of the virus is hugely under-reported.

Chikungunya is a viral disease transmitted to humans by infected Aedes Aegypti mosquitoes. Whilst it is rarely fatal for adults, the infection can cause death in infants, people with weakened immune systems, and vulnerable older people. The virus causes fever and severe joint pain and other symptoms can include: muscle pain, headache, nausea, fatigue and rash.
