Tickborne and Mosquitoborne Illness

Tickborne Diseases

Tickborne diseases can be passed to humans and animals by the bite and feeding of infected ticks. In order to feed, ticks wait on grass, leaves, bushes and other vegetation until a host passes by. Using their front legs, ticks climb on to the host and pierce the skin with their mouth to suck up blood. Although a small percentage of ticks are infected with disease causing bacteria, virus, or parasites, numerous tickborne illnesses are reported each year. Some notable diseases seen regularly in Oklahoma include Rocky Mountain Spotted Fever, Ehrlichiosis, Tularemia and Anaplasmosis. These diseases are transmitted most commonly during the feeding process.

Mosquitoborne Diseases

Mosquitoborne diseases occur when a mosquito that is carrying a virus or parasite bites a person and passes on the virus or parasite, causing them to become infected. While there are many different types of mosquitoes in Oklahoma and worldwide, not all mosquitos carry viruses or parasites that make people sick.

Several diseases transmitted by the bite of a mosquito include West Nile Virus, St. Louis encephalitis, La Crosse encephalitis, and Jamestown Canyon. Mosquitoes pick up the diseases when they feed on infected animals. The organism is then transmitted to humans or animals while feeding.

Some mosquitoborne diseases are found in other parts of the world. Yellow fever is found in tropical and subtropical areas of South America and Africa. Compared to other mosquitoborne diseases, there is a vaccine for yellow fever that travelers may get to protect them from getting infected. Dengue fever is commonly found in Africa, Southeast Asia, Latin America, the Pacific Islands, and the Caribbean. Malaria is another mosquitoborne disease that is caused by a parasite the infects the blood. Malaria occurs mostly in tropical and subtropical areas of Asia, Africa, Central and South America, parts of the Caribbean, and the South Pacific. Travelers to these areas should talk with their doctors about taking prescription medicine to prevent them from getting malaria.
