Viruses and weather

Hello, everyone, we are the popular science popularization of Red Sun Health, trying to answer this question: You can rest assured that at present, the main transmission routes in COVID-19 are respiratory droplet transmission and contact transmission, and there is no evidence that mosquito bites spread to COVID-19? .

Viruses have high requirements for host specificity, you may not understand? Moderator? What does this mean? In fact, it is the living environment. After COVID-19 infects the human body, although it may replicate in cells and enter the blood to form viremia, it is impossible for mosquitoes to spread all the viruses in human blood. What viruses mosquitoes can spread depends on the long-term interaction, mutual adaptation and co-evolution between mosquitoes and pathogens. ? At present, experts say that viruses have high requirements for host specificity. At present, there is no evidence that coronavirus can infect mosquitoes and spread through them.

Then there will be a second question: can mosquitoes spread diseases? Answer:? what's up Mosquitoes rank first among the deadliest animals in 15. According to statistics, the number of mosquitoes that harm human beings will exceed the sum of all other animals in the list every year, so don't take it lightly. Kind? Go feed the mosquitoes. Mosquitoes can spread Zika, dengue fever, Japanese encephalitis, yellow fever, eastern equine encephalitis, Venezuelan encephalitis, Sindbis disease, Japanese encephalitis, St. Louis, West Nile and other viruses, which can cause malaria, Japanese encephalitis, dengue fever and other diseases. Fortunately, these diseases are rare.

Prevention and treatment of mosquito bites Now the weather is getting hotter and hotter, and summer is coming, which is also the season with the most mosquitoes. Although we sometimes take adequate protective measures, we are occasionally bitten by mosquitoes. Then let's talk about the prevention and treatment of mosquito bites.

The first is to clear the accumulated water at home:

A key factor to eliminate mosquitoes is to do a good job in family hygiene. Mosquitoes usually lay eggs in water, such as accumulated water in flowerpot trays, residual liquid in stacked coke cans and beer bottles, and rainwater accumulated in water tanks. Attraction? Mosquito's? The culprit? You should know that some mosquito eggs can survive for up to a year without water, and a small amount of accumulated water is enough for mosquito eggs to develop into young mosquitoes, so you should always clean up the accumulated water and rummage through the cabinets.

Second, it is recommended to configure anti-mosquito equipment:

According to the economic conditions at home, you can use physical mosquito prevention methods such as mosquito traps, screens and mosquito nets. There are also chemical methods such as mosquito repellent incense and mosquito repellent liquid, but families with babies should use them with caution because chemical mosquito killing contains certain toxicity.

The third is to talk to you. What should I do if I am bitten by a mosquito?

Actually, for adults, it's okay. There are many ways to deal with it, mainly children and many parents. When they saw their children bitten by mosquitoes, they immediately thought of it. In fact, this is not right.

The baby was bitten by a mosquito. What should be the first thought? Stop it, okay? Trim your baby's nails every day, and don't scratch blisters at will. Once the scratch is not handled properly, it may cause scar healing, which is what our people say? Scar? .

If it itches badly, you can't just take the medicine for treating dermatitis for adults. Because parents use inappropriate methods to deal with it, use disinfectants to clean it, or use hormone ointment for adults, secondary diseases will be induced. Parents are advised to take their babies to places with many trees and grass as little as possible and take mosquito prevention measures.

Fourth, I'll introduce you to some reliable antipruritic measures.

1. Wash with soap: soap is a sodium salt of higher fatty acid, which is alkaline after hydrolysis, and the liquid formic acid bitten by mosquitoes is acidic. In chemical knowledge, acidic substances and alkaline substances can be neutralized, that is, formic acid in mosquito saliva and sodium salt in soap are neutralized into salt and water. These two things eliminate the symptoms of allergic reaction and will not itch again.

2. Cut a garlic clove and apply it to the mosquito bite with a cross section, which will soon reduce swelling and relieve itching. Next time, you can cut off the thin layer and use it many times.

3. If the bite is itchy, you can play it with your fingers first, and then apply toilet water and wind oil.

4. Applying salt water to the itchy place can soften the lump and effectively relieve itching.

5. When it is swollen and itchy after being bitten by mosquitoes, a small piece of aloe leaves can be washed away and rubbed a few times at the swollen place to reduce swelling and relieve itching.

Finally, I tell you that mosquitoes are special in general. Human feelings? People with developed sweat glands, high body temperature, dark clothes, fast metabolism, make-up and drinking. Therefore, these people go out recently, try to wear long clothes and trousers, and their exposed skin can be coated with anti-mosquito drugs to prevent mosquito bites and various diseases spread by mosquitoes.
