Why is mosquito harmful

This is a potentially life-threatening condition that causes throat swelling, hives, faintness, or wheezing. Anaphylaxis requires immediate medical attention.

If a person notices a mosquito bite and feels any flu-like symptoms or a fever, they should seek medical treatment immediately. Female mosquitoes tend to target some people over others when it comes to feeding. Researchers do not yet fully understand the reasons for this selective process. One study noted that mosquitos have sensors that pick up on carbon dioxide emissions and body odor.

They can then identify which nearby people would make a suitable feeding ground. Body heat, movement, and body odors, such as sweat and lactic acid, might also play a role in attracting mosquitoes. Preventing mosquito bites is always more effective than trying to treat them, given the potential seriousness of the diseases that can transmit during the bite.

Removing sources of standing water around the home and garden can reduce the number of mosquitoes in the area. Using insect repellent may be necessary when doing activities that naturally increase carbon dioxide emissions and bodily odors, such as exercising outdoors. Studies show that it is one of the most effective on the market. DEET works by interfering with the receptors in the mosquito that detect carbon dioxide and body odor, causing them to not detect the person wearing DEET as a potential source of nutrition.

According to the U. Picaridin is a newer type of insect repellent. Working in the same way as DEET, it prevents the mosquito from recognizing its prey. A meta-analysis shows that the preventive effects of picaridin last for more or less the same amount of time as DEET. Picaridin is a safe option for children under 6 months of age , as it contains fewer potentially toxic qualities than DEET. Oil of lemon eucalyptus may be a good option for those who prefer a natural, chemical-free repellent.

People who are planning a vacation should learn about the risk of mosquito-borne illness at their intended destination. They should also speak with a healthcare provider before traveling.

Female mosquitos bite humans to consume blood. The Zika virus is transmitted by the Asian tiger mosquito, the Aedes albopictus, and the yellow fever mosquito.

Areas in Southeast Asia are also affected. These include Thailand, Philippines, and Vietnam. Populations that are at the greatest risks to the Zika virus are women in the first trimester of their pregnancy that will often contract the virus and pass it onto their babies. This is particularly dangerous because the transmission often goes unnoticed. Malaria is arguably the most well-known tropical disease on the planet. It is caused by a unicellular organism called a Plasmodium, spread primarily by the Anopheles mosquito.

Malaria is so deadly and easily transmittable that about 40 percent of all people worldwide are at risk of contracting malaria. The disease progresses in fever episodes and has a mix of symptoms including headaches, pain, sweating, and even diarrhea. You can lower your risk of mosquito bites by using an insect repellent on your skin during hours when mosquitoes are most active, which is from dawn to dusk.

If you plan on going outdoors, especially in wooded and bushy areas, make sure to apply a repellant beforehand. Most insect repellants use active ingredients such as picaridin and DEET to provide protection and last longer than other alternatives. Then we need to engineer mosquitoes that are resistant to all types of infections. Together, this approach conceivably can provide a foundation that has the potential to revolutionize vector control of mosquitoes, he said.
