The US CDC has issued an alert about an outbreak of dengue in Mombasa. This is the first outbreak there in 30 years.
The main way to prevent dengue is by protecting yourself against mosquito bites. The main mosquito that transmits dengue is Aedes aegypti, the one that also transmits yellow fever.
Aedes aegypti bites primarily during the day. This species is most active for approximately two hours after sunrise and several hours before sunset, but it can bite at night in well lit areas. This mosquito can bite people without being noticed because it approaches from behind and bites on the ankles and elbows.
