Do Mosquitoes Cause Meningitis?

Several different viruses can cause meningitis. These viruses include Western equine encephalitis (WEN), Eastern equine encephalitis, and LaCrosse virus.

Most people infected with these viruses do not get sick. However, some people develop severe symptoms and even die from these diseases. The severity of the disease depends on the age and pre-existing conditions of the person. It also depends on the time it takes to treat the person.

Mosquitoes can carry and transmit diseases to humans. The Aedes genus of mosquitoes includes species that transmit disease to humans. These species are found in forests and wooded areas. They lay eggs in small water-filled cavities.

The life span of the female mosquito is usually measured in weeks. In warmer climates, the mosquito season may be active year-round.

In the United States, WNV is the most common cause of epidemic meningoencephalitis. The virus is transmitted by mosquitoes, birds, and mammals. It can affect the brain, blood, and surrounding membranes.

Mosquitoes that carry the virus can transmit it to humans by biting them. Some infected mosquitoes pass the virus to other animals, such as birds, but not to humans.

Some of the viruses that cause meningitis can be very serious. Those with weakened immune systems or who have a compromised health are at greater risk of developing a severe infection. These infections can lead to permanent damage to the brain. In rare cases, the brain can swell, causing seizures and coma.

Some of the symptoms of viral meningitis include a headache, fever, stiff neck, muscle aches, and loss of appetite. It can take five to fourteen days for the symptoms to resolve on their own. Depending on the severity of the disease, a patient may recover from viral meningitis without medical treatment.
