Diseases mosquitoes carry are responsible for the deaths of millions of people throughout history. They have been labeled as one of the most deadly insects in the world. What diseases do mosquitoes carry?
Diseases Mosquitoes Carry
First of all, mosquitoes are deadly because they have the ability to transport diseases and parasites from one animal to another. This is done when the female mosquito takes a blood meal from a host. In many instances, the host is a human and the mosquito is carrying a disease.
Because mosquitoes serve as “vectors” of disease organisms, they can transport a pathogen or parasitic from one organism to another. Furthermore, there are a number of diseases around the world, that are caused by mosquito bites, in which are common in the United States.
Encephalitis vs. Arboviruses
The “encephalitis” are a group of associated diseases caused by viruses. If carried by an infected mosquito, they are called arboviruses.
St. Louis encephalitis is the most common arbovirus disease in the United States. Mosquitoes are infected by birds as they have a blood meal. Humans are then infected from the mosquito bite.
Consequently, this viral infection can cause fever, severe headaches, nausea, and vomiting in humans. These symptoms can be worse in people over 60 years old. There can be a low percentage of fatalities to the elderly.
La Crosse Encephalitis
La Crosse encephalitis cases have been reported in the mid-southern states including Tennessee in recent years. Many of these reported cases were children under fifteen years old. This virus is carried by rabbits, squirrels and other rodents. The mosquito will feed on these animals and then can transfer the virus to humans with a bite.
This virus can be carried by the most common mosquitoes in the region, including the Asian tiger mosquito. Consequently, this disease causes many symptoms. Headache, lethargy, fever and nausea are common symptoms under 16 years of age. Fatalities in clinical cases are less than one percent.
Eastern Equine Encephalitis
Eastern equine encephalitis is a virus transferred from birds to mosquitoes. The mosquito then carries the virus to equines (horses) and people by taking a blood meal. This can be a potentially deadly virus to young children.
The virus is monitored in the field by capturing birds and checking for the virus. High infected bird local populations can raise concern for human and equine infections. Vaccines are available for horses but not humans. This virus is not common in Tennessee but cases have been reported.
Dengue is a viral disease not currently a common concern in the United States. Most reported cases originated in other countries as people traveled. Furthermore, this disease can be common on other continents. This disease can cause high fever, pain in joints and a rash.
Facts pertaining to mosquito-borne diseases:
- Many mosquito-borne viruses cannot be transferred by a bite from one human to another.
- Birds are a very common vector for mosquito-borne diseases.
- Most of these diseases are from viruses.
West Nile Virus
West Nile Virus has been reported over recent years. Birds are also a vector for this disease and mosquitos will transfer it to humans. Most people will not have any or just minor symptoms of the virus.
Furthermore, a few people may have fatigue, headaches, joint pains, diarrhea, and rashes. A very small percentage of people may have damage to the central nervous system. One sign of West Nile virus in an area is numerous dead birds especially ravens and jays.
Zika has also been in the news. The CDC has reported that mosquito-borne Zika infections have identified in the United States.
Normal symptoms may include headaches, rash, fever, and joint pain. This virus also causes birth defects in pregnant women. To add, this virus is transmitted by mosquito bites and also human to human sex.
