Although the rain is frequent this year, according to the mosquito detection data of the Municipal Center for Disease Control, the mosquitoes in Jiangmen City are basically the same as last year. It is expected that the trend of dengue fever will be similar to last year.

It is understood that the affected person is a 23-year-old Taishan man who was infected with the disease in the Republic of Nauru on April 6 and entered the country on April 15th. He lived in Taishan Wencun on April 16-21, and was on April 18th. The city center hospital was diagnosed.

Anti-mosquito first trick: clean up the mosquito breeding ground
It is understood that dengue fever is an acute infectious disease transmitted by Aedes mosquitoes. There is no dengue vaccine that can be applied. The only effective measure to prevent and control dengue fever is to clean the mosquito breeding ground to control mosquito vectors and cut off the transmission route.

The Municipal Center for Disease Control and Prevention reminds the public to do personal protection first. They should hang mosquito nets during naps or evening breaks. They should pay attention to mosquito bites when resting in parks, on the street, at activities, or in activities such as dengue fever. Sleeve, light-colored clothes, reduce the exposed area of ​​the skin, and apply anti-mosquito cream to the exposed parts.

Second, it is necessary to protect the home environment. The water tank used by the residents should be covered and cleaned every 3 to 5 days. The vases and bonsai in the room should be changed every 5-7 days. In addition, in the aspect of outdoor environmental protection, it is possible to turn over the cans in the outdoor places where mosquitoes are inhabited, fill the bamboo tree holes, and regularly eliminate large numbers of mosquitoes without leaving dead spots, completely eliminate mosquito breeding sites; water or water bodies that cannot be removed outdoors cannot be sealed. Various outdoor landscape water bodies such as wells, sewers, fountains, pools, etc., are placed in the anti-mosquito granules. At the same time, for the protection of key sites in construction sites, it is necessary to clean up the accumulated water in time, and to release the anti-mosquito drugs in the accumulated water when the cleaning is difficult.

Anti-mosquito second trick: hanging mosquito nets, correct use of mosquito coils
The summer of mosquito bites has arrived, and mosquito coils have become one of the main means of mosquito killing. Recently, reporters visited the major supermarkets in Jiangmen and found that whether it is traditional dish-type mosquito coils, electronic mosquito-repellent incense, liquid mosquito-repellent incense, etc., all product packaging boxes are marked with the words "low-toxic" or "micro-poison". The mosquito-repellent product packaging box is also marked with “Pesticide Registration Certificate Number” and “Pesticide Production Approval Document Number”.

However, for families with children at home, doctors generally recommend not to ignite mosquito coils. It is best to install screens and hang mosquito nets. Chen Yanjuan, deputy director of the Children's Health Center of Jiangmen Maternal and Child Health Hospital, said that children are victims of mosquitoes due to their low immunity and tender meat, and the reaction is often more serious. After the bite, they are even red and swollen.

"Many people don't need mosquito nets now, but for children it is recommended to use mosquito nets." Chen Yanjuan said that although there are many smokeless mosquito coils and electric mosquito tablets on the market, they have always added industrial ingredients in the production process. It is also difficult to guarantee whether the supervision is in place.

“In addition, the children’s airway sensitivity is high, and asthma and allergies are prone to occur. Mosquitoes that are irritating to the respiratory tract may also become a potential factor for sensitization. It cannot be ruled out. If you use a mosquito net, you can give your child a physical barrier, dustproof and more Breathable and ventilated."

Anti-mosquito 3rd trick: homemade Chinese medicine sachet

The Chinese doctor, Mr. Deng, no longer has to worry about the 3-year-old daughter being bitten by mosquitoes in the summer. This summer, in order to prevent skin-sensitive daughters from being bitten by mosquitoes, he has tried four prescriptions to equip his daughter with a Chinese herbal medicine anti-mosquito sachet. The formula has also expanded from the initial 9-flavor to 13 flavors.

"Before, my daughter was always bitten by mosquitoes. Because of itching, I often scratched the bleeding. I made blood on the sheets. I had to be tossed by mosquitoes for an hour before going to bed." At first, Dr. Deng bought the market. Mosquito paste prevention, but the effect is not ideal, and because the child is often wasted, it is not used again.

Seeing that her daughter was suffering from this, Dr. Deng remembered that Chinese mosquitoes did not like certain aromatic Chinese medicines, and they thought about making their own anti-mosquito bags. At first, he chose nine herbs such as clove, wormwood, and mint to try. Every 15 grams or so, make a sachet to hang on his daughter's chest.

"Mosquitoes don't like to smell that smell. One time, mosquitoes stopped at their foreheads, but they quickly flew away." Excited Dr. Deng used a cup to hold some homemade powder in every room at home. "I found mosquitoes really." A lot less." In order to improve the prescription, Dr. Deng has been equipped with the fourth sachet recipe this year, and the number of Chinese herbal medicines has increased to 13.

Discuss whether mosquito coils are poisonous?

City CDC: Correct use is basically harmless

The discussion about whether mosquito coils are toxic has also plagued many citizens for many years. Some doctors said that the mosquito-repellent incense contains pyrethroids, which cannot be said to be completely harmless to the body. In this regard, Jiangmen City CDC said that the correct use of mosquito coils is basically harmless to the human body. The public can try to choose non-irritating products marked with the words "low toxicity" and "micro-poison", as well as some qualified and qualified brands.

Is there any poison in the mosquito coils?

“If the mosquito-repellent incense is not poisonous? How to kill or drive away the mosquitoes?” This question is not only the case of Chen Rongjian, the director of the emergency department of the Municipal Hospital, but also the trouble of many people who use mosquito-repellent incense for a long time. According to him, the pyrethroid component in mosquito coils is itself a pesticide substance. At present, most of the mosquito-repellent fragrances on the market are pyrethroid-containing drugs. These products first paralyze the nervous system of the insects, so that they lose their biting ability and even cannot recover.

"The so-called poison or non-toxicity is a substance that causes certain damage in the human body, but does it have any potential harm to the human body before it reaches the damage standard? Especially in air-conditioned rooms, mosquito-repellent incense or mosquito-repellent liquid, etc., long-term chemistry Drugs may affect the human body." It is understood that if the pyrethroids are mildly poisoned, mainly manifested as headache, dizziness, fatigue, etc., severe cases may have muscle tremor, increased secretions, or problems with breathing and nerves. And there is no special antidote.

Correct use is basically non-toxic

In this regard, Jiangmen City CDC said that the correct use of mosquito coils is basically harmless to the human body, and reminded the public to be cautious when purchasing mosquito coils, to see the instructions. “Whether the pesticide registration certificate number, production license number and product standard number are indicated on the package, and the exact pharmaceutical composition and content are the two most important indicators of the qualified product. In addition, pay attention to the selection of “low toxicity” and “microtoxicity”. "There are no stimulating products such as the words, as well as some qualified and qualified brands."

At the same time, the Municipal Center for Disease Control and Prevention reminded that mosquito coils only act as mosquito repellents. Mosquito-killing tablets can really kill mosquitoes. It is recommended that households on low floors install mosquito screens and mosquito nets. When mosquitoes are particularly abundant, mosquitoes can be used to kill mosquitoes. It is also important to remove mosquito breeding grounds. The Municipal Center for Disease Control specifically reminds that after the ignition of the mosquito-killing tobacco tablets, people must leave the room and close the doors and windows for about 30 minutes. Before entering the room, the doors and windows should be opened for 5-10 minutes.
