Contractible Diseases from Mosquito Bites
Worldwide, mosquitoes are responsible for more human deaths annually than any other living creature. There are a number of dangerous diseases that can be contracted via mosquito bites that you should be aware of in the United States.
Listed below are 3 common mosquito-transmitted diseases in the U.S.
West Nile Virus (WNV)
A potentially serious illness, West Nile Virus, or WNV, is believed to be a seasonal epidemic in North America, flaring up in the summer annually. The disease is most commonly spread via the bite of infected mosquitoes. Mosquitoes become infected after they feed on birds infected with WNV.
West Nile Virus first garnered the attention of the national media after an outbreak in New York City in 1999 resulted in 7 deaths. The number of cases reported each year continues to rise with the state of Texas, most recently, reporting the highest number of WNV human cases and deaths.
La Crosse Virus (LAC)
The Centers for Disease Control and Prevention estimates between 80-100 La Crosse encephalitis cases are reported every year. The majority of cases have been reported in the northern Midwestern states such as Minnesota, Wisconsin, Illinois and Ohio.
However, in recent years cases have been reported in eastern and southern U.S. states. Severe cases of La Crosse encephalitis are most common with children under the age of 16.
St. Louis Encephalitis (SLE)
From 1964-2009, an average of 100 human cases of St. Louis encephalitis have been reported in the United States. SLE cases are most commonly reported in the late summer and early fall. The principle vectors of the disease are Culex species mosquitoes.
In 1975, almost 2,000 cases of St. Louis encephalitis were reported with the majority of the cases reported in central U.S. states. Since 1975, the disease has not followed an endemic pattern.
