How to "defend" against mosquitoes in summer?
How to deal with mosquito bites properly?
Yangcheng Evening News reporter interviewed experts for this.
Squeeze pimples may cause secondary damage
"Why are there so many mosquitoes in Guangdong? Because the climate here is too suitable for mosquitoes to survive." Sun Ledong, chief physician of the Department of Dermatology, Fifth Affiliated Hospital of Southern Medical University, introduced that mosquitoes like humidity. Guangdong itself has humid air and abundant surface water sources. Coupled with the continuous rainfall in the past few days, it has created conditions for mosquitoes to multiply; in addition, the most suitable temperature for mosquitoes to survive is 10 ℃ to 35 ℃, and the temperature in most parts of Guangdong is very consistent with this, which has become a mosquito rampant " catalyst".
"Although mosquito bites can cause pimples and itching, doctors do not advocate squeezing the mosquito bites." Sun Ledong introduced that mosquitoes will inject formic acid after biting the skin, which is relatively less toxic, and the human body will quickly neutralize it. Metabolized, if necessary, you can use some topical ointment.
However, squeezing the papules bitten by mosquitoes will cause secondary damage to the skin. If the wound is combined with secondary infection due to various problems, it will bring serious consequences.
"Mosquitoes, mites, tsutsugamushi, and ticks are also known as the four major pests. In addition to biting the skin and causing rashes, they also transmit many diseases." Sun Ledong introduced that mosquitoes are closely related to many infectious diseases, such as epidemics Japanese encephalitis, dengue fever, malaria, etc.
Physical isolation is the most effective way to prevent mosquitoes
"To eliminate mosquitoes and prevent mosquitoes, we must start with its living environment." Sun Ledong introduced that mosquito control must first do a good job of sanitation and cleaning to keep indoor and outdoor water bodies clean.
The fish tank and aquatic plants in the home should be replaced with purified water at least once a week, and the dark corners of the home should be prevented from accumulating water to prevent mosquitoes from breeding indoors.
"There are many ways to prevent mosquitoes, but the most important one is physical means." Sun Ledong emphasized that home mosquito control and mosquito control can be done by means of screens, mosquito lamps, mosquito nets, and electric mosquito swatters.
When going out, if you are afraid of mosquito bites, you can choose long clothes and trousers. The color of the clothes should not be bright, so as to avoid attracting mosquitoes.
In addition to physical isolation, many chemical repellents are also effective means of mosquito control.
"Mosquito repellent products such as mosquito coils and electric mosquito liquid can be used indoors, but you need to pay attention to the chemical composition and usage." Sun Ledong introduced that all kinds of mosquito repellent products have certain toxicity and are not recommended for children under 2 months old. When using, pay attention to indoor ventilation to avoid poisoning caused by high concentration.
It is understood that there are many different active ingredients in mosquito repellent products on the market. Among them, DEET has a good repellent effect and a long duration, and can be directly applied to the skin, but there is a risk of damage to clothing, and the concentration of children should not exceed 30%; Icaridin is relatively mild and less irritating to the skin, and the concentration for children should not exceed 20%.
