Chikungunya and Mosquitoes


West Nile virus, Malaria, Dengue fever and Encephalitis are afflictions that are commonly associated with mosquitoes and have been contracted by humans in countries all around the world. A less-well-known but potentially serious mosquito-borne disease is Chikungunya, a virus that can cause of wide range of uncomfortable and even painful symptoms. There currently is no vaccine that can prevent Chikungunya or medication that can combat the virus once an individual becomes infected

Facts about Mosquitoes and Chikungunya

According to the Centers for Disease Control and Prevention, most people who are infected with the Chikungunya virus as the result of a mosquito bite will develop some symptoms. These symptoms typically begin to occur within 3-7 days after being bitten and can include fever and joint pain, headache, joint swelling, muscle pain and rash. While the virus rarely causes death, these symptoms can be quite severe and often disabling. Newborns, the elderly and people with certain medical conditions face a higher risk of experiencing severe symptoms. Most infected individuals make a full recovery within a week, although some may experience lingering joint pain for several weeks or months.

Concerns about Chikungunya in the World

What concerns many entomologists and health professionals is that Chikungunya can be spread by day-feeding Asian tiger mosquitoes with greater efficiency than other mosquito-borne diseases such as dengue fever and West Nile virus. Chikungunya can also spread from one human host to another without a reservoir like any other mosquitoes. This makes Chikungunya different from the West Nile virus, for instance, which must first replicate inside a bird before it can pass from a mosquito to a person. Thus, the virus has the potential to spread rather quickly to other parts of Europe
