How Do Mosquitoes Transmit Diseases?

Wouter

During the past 100 years, mosquitoes have been known to carry and transmit a variety of diseases. Some are fatal, while others are not. Some of these diseases are a result of a virus, while other illnesses are the result of a parasite.

Some of the most dangerous diseases transmitted by mosquitoes are malaria, dengue, and Zika virus. Although these diseases are not fatal, they can lead to complications such as joint pain, vomiting, and a rash.

The symptoms of malaria vary according to the immune system of an individual. The most common signs are fever, headache, and chills. Other less severe infections, such as encephalitis, can cause backache and chills.

Aedes aegypti and Anopheles species of mosquitoes are the main vectors for malaria. These mosquitoes bite humans and animals, feeding on their blood. When an infected mosquito bites an uninfected host, it transfers the virus to the host through saliva.

Aedes aegypti mosquitoes are also responsible for the spread of yellow fever. In addition, they spread several other diseases including dengue, chikungunya, and Rift Valley fever.

Mosquitoes can carry a variety of viruses, including Zika and West Nile virus. Some of these viruses are capable of causing encephalitis, meningitis, and joint pain. In the United States, the mosquitoes that carry these viruses can be found in every state except Alaska.

Climate change is changing the distribution of mosquitoes and their ability to transmit disease. With warmer temperatures and changes in precipitation, more mosquitoes are likely to become adult and more widespread. This means more people are likely to be exposed to the viruses that they carry, which can lead to more infections.
