Mosquitoes are tiny insects that can cause big problems all over the world by carrying deadly diseases to humans. It is creating increasing concern for researchers around the world. After the latest research by Japanese scientists, most mosquitoes are evolving. making it invincible and unable to be killed by pesticides or sprays to kill mosquitoes like before
Shinji Kasai, a researcher at the National Institute of Infectious Diseases in Japan, has studied mosquito samples in several countries. Especially in Vietnam and Cambodia where dengue fever outbreaks are found. It was found that mosquitoes from Cambodia and Vietnam accounted for most of the mosquitoes that had the mutation. “Super mosquito” resistant to pesticides Especially the type of drug “Pyrethroid”, which is a drug that sprays mosquitoes during the rainy season that we spray at home.
In the report states that insecticides in that study. It can only kill 10% of the mosquitoes, or sometimes it can’t kill any of them. This was shocking: 78% of Aedes aegypti mosquitoes carried a mutation called L982W, making them more resistant to mosquito repellents. The Aedes aegypti can carry yellow fever, dengue fever, malaria, and the Zika virus. Although this study was found only in Cambodia and Vietnam. But it is possible to gradually spread to other Asian countries including China and Thailand Consequently, there should be constant surveillance and monitoring of the presence of mosquitoes in the country.drug resistantor not, especially in Southeast Asia This poses a threat to the public health system to deal with more infectious diseases.
Kasai also stated that It is important to realize that the insecticides that are normally used may no longer be effective once morest mosquitoes. After this, public health officials should choose suitable insecticides that are more effective in controlling mosquitoes. such as switching chemicals in pesticides to reduce the mutation or resistance to any kind of chemical
this discovery This is a major concern for public health systems and the eradication of mosquitoes. In the past 50 years, dengue cases have increased 30 times, with the US Centers for Disease Control and Prevention estimating as many as dengue fever worldwide. 400 million people a year, and 21,000 of them die due to lack of access to vaccines or treatment. Therefore, mosquito spraying is the only way to best control the spread of the disease. But if this method still doesn’t work. It will be the hard work of doctors, nurses who have to deal with patients that will increase. Including relevant agencies that have to do their homework to find ways to get rid of mosquitoes that will be more effective in fighting mosquitoes. As for the people, they have to find ways to protect themselves from these mosquitoes in order to continue to survive.
