List of Lethal diseases caused by Mosquitoes

Mosquito is a notorious, infamous creature whose bite irritates your skin and causes many lethal diseases. Many mosquito-borne diseases are fatal, killing around more than 1 million people every year around the world.


Let's take a look at few diseases caused by mosquitoes:               

1. Malaria: Malaria is a mosquito-borne disease that has its roots in Africa. The plasmodium parasite is transmitted through the bite of a female Anopheles mosquito. It is an old disease, and so specific anti-malarial drugs have been available since more than 50 years. The tropical and subtropical regions are more susceptible to malarial infection. More than 300 million cases of malaria are still reported annually throughout the world. According to CDC (Centers of Disease Control), more than 1 million people in the world die due to transmission of malaria. symptoms of malaria fever are similar to dengue 

2. Dengue Fever: Dengue, also known as "breakbone fever" is a serious and debilitating disease that is widespread in America, Africa, and Asia. It is transmitted through the Aedes aegypti and Ae. albopictus species of mosquitoes. Dengue has no specific treatment and only its symptoms can be managed. Dengue is not usually fatal, but if left untreated, it could lead to death. According to the CDC (Centers of Disease Control), the mortality rate of hemorrhagic fever is around 5%.

3. Chikungunya: Chinkungunya is a viral disease that is transmitted by the Asian Tiger mosquito (also known as Aedes albopictus). It has its roots in the Caribbean islands. Intense joint pain is the main symptom of Chikungunya. Pain management is the prime treatment of Chikungunya.

4. Yellow Fever: Yellow fever, which is more than 400 years old, is presently prevalent only in the tropical regions of Africa and America. Though it is not prevalent in India, caution needs to be taken while travelling to African and American countries. It is a viral disease transmitted by mosquitoes and haemorrhagia is a common symptom. It's called "Yellow" fever because jaundice is observed in some patients.

5. West Nile Virus (WNV): West Nile Virus is a mosquito-borne disease that can be transmitted to humans, birds, and horses. WNV patients show no flu-like symptoms, but some elderly patients become extremely sick due to its infection. 1 out of 5 individuals infected with the virus show symptoms of WNV. Very few people experience neurological problems due to WNV, which could be fatal.

6. Eastern Equine Encephalitis (EEE): EEE is a rare viral disease transmitted to human beings, horses, and birds through mosquitoes. There are very few cases of EEE infection in the US every year, however, many cases are reported in the Gulf States. The mortality rate of this disease is 33% in the US. It is associated with significant brain damage. EEE is also known as "sleeping sickness".

There is no specific treatment for this disease and only symptoms can be managed. No specific therapy exists for EEE, and only supportive treatment such as IV transfusion and respiratory support can be provided by hospitalization to EEE patients.
