Mosquitoes can carry many types of diseases that are caused by bacteria, parasites or viruses. These diseases include:
Malaria - Malaria is caused by a parasite that is transmitted by an Anopheles mosquito. The parasite grows in your bloodstream and can produce symptoms that develop anywhere from six to eight days to several months after infection.The symptoms include fever, chills, headaches, muscle aches and general malaise (similar to flu symptoms). Malaria is a severe disease that can be fatal, but can be treated with antimalarial drugs. Malaria is prevalent in tropical or sub-tropical climates.
Yellow Fever - Yellow fever no longer occurs in the United States or Europe, but it is prevalent in Africa and parts of South America. It is transmitted by the Aedes aegypti mosquito. Yellow fever produces symptoms similar to malaria, but also includes nausea, vomiting and jaundice. Like malaria, yellow fever can be fatal. There is no treatment for the disease itself, only the symptoms. Yellow fever can be controlled by vaccination and mosquito control.
Encephalitis - Encephalitis is caused by viruses that are transmitted by mosquitoes such as the Aedes mosquitoes or Culiseta mosquitoes. The symptoms of encephalitis include high fever, stiff neck, headache, confusion and laziness/sleepiness. There are several types of encephalitis that can be transmitted by mosquitoes, including St. Louis, Western equine, Eastern equine, La Crosse and West Nile. West Nile encephalitis is on the rise in the eastern United States, which has raised concerns about mosquito control .
Dengue Fever - Dengue fever is transmitted by the Asian tiger mosquito, which is native to East Asia and was found in the United States in 1985. It is also transmitted by Aedes aegypti in the tropics. Dengue fever is caused by a virus that produces a range of illnesses, from viral flu to hemorrhagic fever. It is especially dangerous for children.
