borne virus spread by mosquitoes in East and West Africa, as
well as Zimbabwe. Symptoms include high fever, joint pain, headache
and swollen lymph nodes. Sometimes there is a general rash.
Recovery can take two weeks.
There have been no serious long-term problems after an infection but pregnant
women have had increased miscarriage because of infection. There is no specific
treatment but general mosquito precautions should be observed. This disease
co-exists with malaria so general precautions against malaria should be observed.
