Question: What type of insect transmits yellow fever?
Answer: The yellow fever virus is found in tropical and subtropical areas of Africa and South America. The virus is spread through mosquito bites. Symptoms take 3–6 days to develop and include fever, chills, headaches, backache, and muscle aches. About 15% of people who get yellow fever develop serious illness that can lead to bleeding, shock, organ failure, and sometimes death. The disease is caused by the yellow fever virus and is spread by the bite of an infected female mosquito. It infects only humans, other primates, and several species of mosquitoes.
