A report by the Centers for Disease Control and Prevention (CDC) says more than 1.5 million people worldwide die each year and hundreds of millions of people become sick with mosquitoes. Below is a list of dangerous diseases caused by mosquito bites.

  1. Malaria

First of all to mention the disease caused by mosquitoes that mention everyone knows. That is malaria. Malaria is a disease that causes more than 600,000 deaths a year worldwide. The cause of malaria is that female Anopheles mosquitoes transmit the Plasmodium parasite to the human body through a bite. High fever, chills, and severe influenza-like symptoms can be fatal if left untreated. Diseases can be prevented by getting sleep deprivation, insect repellent, long sleeves, and can be treated, but it still causes many deaths.

  1. Dengue fever

Next is dengue fever. Dengue fever is one of the most dangerous diseases caused by mosquitoes. It mainly occurs in people in tropical and subtropical climates such as Puerto Rico, the Pacific Islands, Latin America and Southeast Asia. When a dengue fever occurs, the person may have fever, rash, headache, bruising and bleeding of the teeth, severe stomach pain, diarrhea, and subcutaneous haemorrhage. Dengue now has vaccines.

Zika virus was first found in Africa in the 1940s, then spread to South, Central America, Mexico, the Caribbean, Southeast Asia and the Pacific Islands. The disease is transmitted mainly through the bite of an infected Aedes mosquito. For most people, the symptoms of the virus are mild: fever, rash, joint pain, red eyes, and self-healing within a week.

However, scientists are suspected that the disease poses a risk to pregnant women and the fetus, which can cause congenital malformations, which can lead to brain shrinkage and small head disease. Small head disease that children do not develop fully, delayed intellectual development and other problems. There is no specific anti-Zika vaccine. The CDC recommends that pregnant women avoid travel to affected areas.

West Nile virus is caused by mosquitoes. This disease is common in animals and birds but recently it has been reported that the virus has been found in human cells. It spreads through saliva and from mother to baby through breast-feeding. Most infected people do not have any symptoms. About 1 in 5 people have fever, flu, fatigue, diarrhea, joint pain, vomiting, rash. In some severe cases, the disease can cause serious infection, leading to seizures, swelling of the brain, meningitis, even death.

Japanese encephalitis is an infectious disease to the brain caused by mosquito bites. It is prevalent in Asia, the Western Pacific, Central and South America. Some serious symptoms of the disease include high fever, convulsions, coma and severe headache. Japanese encephalitis has a high mortality rate and if the patient survives, severe sequelae are left. Vaccination is one of the effective measures to prevent encephalitis.
