What Are the Most Dangerous Diseases Caused by Mosquitoes?

Mosquitoes are a summer nuisance that no one likes to deal with. They are found all around the world and they can breed just about anywhere they find standing water.

These pests not only bite and leave itchy, red welts, but they can also be dangerous. Mosquitos are known to harbor and transmit many diseases. While some diseases are more common than others, they all have the potential to be deadly. Here are 11 diseases carried and transmitted by mosquitoes.

Top 11 Diseases Caused by Mosquitos- know the signs

1. Japanese Encephalitis

The mosquitoes that carry Japanese Encephalitis are found in marshes, standing waters, rice fields. Humans contract this disease through a bite and the symptoms can be extremely mild or cause a serious amount of damage. This disease attacks the central nervous system, including the brain and spinal cord. The severity of the reaction depends on how the body reacts to the bite.

2. Rift Valley Fever

Rift Valley Fever is an acute, fever-inducing viral disease. This sickness affects both humans and animals. It usually takes two to six days for the infection to take hold. Victims experience general weakness, back pain, and dizziness as the sickness develops. More serious symptoms include ocular disease, encephalitis, or hemorrhagic fever.

3. Ross River Disease

Those infected with Ross River Disease may not show symptoms right away. In fact, 55%-57% of infected individuals don’t have any symptoms. For those who do experience symptoms, they can include swelling, joint pain, stiffness, and tiredness. Among the milder infections transmitted by mosquitoes, patients recover from this sickness within a few weeks.

4. Elephantiasis

Mosquitos carrying elephantiasis can be found in the tropics, subtropics, and 73 countries. This disease is painfully disfiguring and can potentially cause permanent disability. The result can have devastating physical, mental, social, and financial issues. The swelling is intensely painful and can have life-long consequences.

5. Encephalitis

Encephalitis is a virus that causes inflammation around your brain and spinal cord. Aside from Japanese Encephalitis, there are several other types of encephalitis. The type depends on where you contract the disease. Symptoms begin with a fever and sore throat. More severe side effects include confusion, seizures, and muscle weakness. Over time, this life-threatening disease can cause permanent brain damage.

6. Dengue Fever

This tropical virus can transmit about a week after a mosquito bites an infected person. One mosquito can easily transfer the disease to a vast number of victims. The virus quickly multiplies and damages cells. The symptoms begin with a high fever and include headaches, back, and joint pain, rashes, and eye pain. The fever lasts for about a week. Infected people can also experience bruising and bleeding. Dengue fever can be fatal if not treated.

7. Chikungunya

Chikungunya is a pathogen virus transmitted by mosquitoes. Found originally in the Caribbean, it has been diagnosed in 35 states in the US, Puerto Rico, and the Virgin Islands. This dangerous disease has no cure, but it is not fatal. Symptoms of chikungunya start with intense joint pain. Victims experience sudden fever, chills, headache, nausea, vomiting, lower back pain, and rash. Again, while it is not necessarily fatal, it will incapacitate those who contract it.

8. Yellow Fever

Flavivirus located in Africa and South America. Once transmitted, it incubates in the body three to six days before symptoms show. Victims experience fever, chills, headache, and nausea. Following a short remission, the disease will return with more severe symptoms: nosebleeds, bloody vomit, abdominal pain. Yellow fever can be deadly. No known treatment exists aside from vaccination.

9. West Nile Virus

West Nile is a viral infection carried in bird blood. Mosquitoes feed on infected birds and pass it off onto humans. This disease multiplies in human blood and heads to the brain. Like encephalitis, West Nile affects the central nervous system and causes inflammation. It causes high fever, headaches, swollen lymph nodes, and a stiff neck. Those who contract this disease can experience convulsions, coma, or even death. Infected individuals can experience permanent neurological damage. 1 in 150 infected with West Nile Virus experience severe symptoms.

10. Malaria

Female mosquitos pick up parasites, Plasmodium falciparum or Plasmodium Vivax by feeding on infected humans. The parasites develop within 10-18 days and they are passed on through the mosquito’s saliva. This disease feeds on blood cells and moves into the liver. Victims experience fever, chills, sweating, headaches, and flu-like symptoms. If left untreated, malaria can cause kidney failure and death.

11. Zika Virus

Zika Virus has become a public health issue across the Americas. Since February 1st, 2016, the Zika Virus has spread across the US. Zika can cause a rare birth defect called microcephaly – a neurological disorder that results in babies being born with abnormally small heads and development issues. This disease can be transmitted by a mosquito bite or sexually. Unfortunately, there is no cure.
