Chikungunya virus infection in the Caribbean islands and the Americas
This is a virus passed on by being bitten by infected mosquitos. The incubation period is typically 3–7 days and symptoms include acute onset of fever and joint pain. Other symptoms may include headache, conjunctivitis, nausea/vomiting, or rash. The symptoms usually go within 10 days but in some may last months especially the elderly and people with underlying health issues such as high blood pressure and diabetes.
As this is a virus, there is no medication to prevent or treat the disease and anti-malarial tablets such as Chloroquine will not have an effect on it.
Bite avoidance measures should be taken and followed firmly to reduce the likelihood of being bitten.
The affected mosquitoes tend to bite during the day so wear long-sleeved clothing and trousers wherever possible and ensure that a strong insect repellent is used and reapplied regularly, especially after swimming.
You should also sleep under a mosquito net and if you are staying for a long time or are unsure of the hotel/hostel, it would be advisable to take a battery operated or plug-in mosquito killer for your room to kill any lingering mosquitos.
