O'nyong-nyong Fever

This is a mosquito-transmitted arboviral illness similar to Chikungunya fever. The name comes from the Nilotic language of Uganda and Sudan and means "weakening of the joints."

Occasional epidemics occur, but fatalities are not reported. Travellers should take measures to prevent evening and night-time mosquito bites. Insect-bite prevention measures include a DEET-containing repellent applied to exposed skin, insecticide (permethrin) spray applied to clothing and gear, and use of a permethrin-treated bednet at night while sleeping.
