Mosquito bites are itchy bumps that appear on the skin when mosquitoes feed on the skin and the blood. Most mosquitoes are harmless but can cause swelling, soreness, and redness. The red bump and itching are not caused by the bite itself, but by a reaction of the body's immune system to proteins in the mosquito's saliva. The saliva carries certain viruses or parasites which can cause severe illnesses like dengue, yellow fever, malaria, and some types of brain infection (encephalitis)
The mosquitoes that are female mosquitoes, need protein to nourish their eggs. They get it by feeding on warm-blooded creatures like birds, horses, and human beings. When a mosquito bites an infected animal (or a person) and then bites a human being it transmits the disease to the blood through its saliva.
Tips to limit exposure to mosquitoes and protect yourself from bites
• Eat healthy to keep the immune system strong.
• Exercise regularly. It increases the body's immune response.
• Take precautions to reduce the risk of being bitten if you visit areas known to have more mosquitoes.
• Wear long-sleeved clothes that cover the arms and legs.
• Avoid going out at dusk, when there are more mosquitoes.
• Close the windows of the house early in the evening. Put wire meshes on windows and doors, use mosquito nets and repellants.
• Ensure there is no stagnant water around the house; check every alternate day. Open drains, shallow pools, air cooler water, and flower pots are major breeding areas for mosquitoes. Keep underground and overhead tanks covered and clean, both before and after the monsoon.
• If you see any infected or dead birds or animals in your locality, call the municipal authority immediately. They carry viral diseases, which may be transmitted by mosquitoes to humans.
• Consult a doctor if mosquito bites seem to be associated with fever, headache, and body aches.
