As of 24: 00 on February 9th, according to official website's "Distribution of Pneumonia Infected in novel coronavirus? According to our data, 40235 cases were diagnosed in China (including Hong Kong, Macao and Taiwan), 23589 cases were suspected and 909 cases died unfortunately. It can be described as "aggressive."
Even so, as long as we take preventive measures, we can stay away from the virus. How to effectively prevent viruses? First of all, it depends on how the virus spreads. From June 5, 20438 to October 27, 2020/KLOC-0, the "Diagnosis and Treatment Plan for Infected Pneumonia in novel coronavirus (Trial Fourth Edition)" jointly issued by the General Office of the National Health and Wellness Commission and the General Office of state administration of traditional chinese medicine pointed out that droplet transmission through respiratory tract is the main route of transmission, and it can also be transmitted through contact. Now that we know the route of transmission, prevention is very simple. Xiao Cun has compiled the following information for everyone.
Knowledge is coming. Ang, take a notebook and write it down.
The most effective way to prevent the spread of respiratory droplets is:
1. Wear a mask. It is suggested that ordinary people and service personnel in public places use medical surgical masks during their posts. If conditions permit and physical conditions permit, you can wear a medical protective mask. It is suggested that high-risk groups who may be exposed to suspected or confirmed cases wear medical protective masks (N95 and above) and goggles. Masks should be changed regularly, and can't be worn backwards. When taking off the mask, don't touch the contaminated area on the front of the mask, just take off the lanyard from the ear.
2. Cover your nose and mouth with a paper towel or elbow when sneezing or coughing to prevent the spread of bacteria and viruses from causing mucosal infection.
3. Open the window for ventilation, and ventilate at home three times a day for 20 ~ 30 minutes each time. A small amount of savings will be provided for everyone, so keep warm when opening the window in winter. If you are in a car, you can skillfully use the "skylight negative pressure principle" to adjust the skylight to the tail-up mode and open the external circulation, which will not only make the air flow faster, but also make the noise very small. As for the small partners who don't have skylights in the car, they should open two-finger gaps in each of the three windows, or two-finger gaps in both the main driving window and the right rear window, depending on the number of people in the car, and try to ventilate as much as possible under the premise of reducing wind noise.
In view of the route of contact transmission, the most effective prevention method is:
1. Avoid going to crowded public places, crowded places with poor air circulation, and markets selling live animals (poultry, seafood, wild animals, etc.). ), avoid aerosol transmission, and try to travel by private car.
2. Wash your hands frequently and run water. Wash your hands with soap and water or alcoholic hand sanitizer for at least 20 seconds. If you have to travel, I suggest you put on disposable gloves and see if there are any disposable gloves left by crayfish at home. This can also avoid our direct contact with the virus to a certain extent. I want to remind you to wash your hands after taking off your gloves.
3, cleaning on time, keep the home environment clean and tidy, if there is alcohol at home, you can use alcohol to wipe common items for disinfection, such as keys, door handles, mobile phones, bedside tables, etc. High-temperature tableware can also be disinfected in a disinfection pot or boiling water for 30 minutes. If you have chlorine-containing disinfectants (such as 84 disinfectant) at home, you can also mix them in an appropriate proportion (84 disinfectant? 10mL+ 990mL water), mop the floor 1~2 times a day.
In addition to maintaining cleanliness and hygiene at home, how can friends who travel frequently avoid it? Next is the second message Xiao Cun sent to everyone.
Intelligence 2: rational use of car air conditioning? Car disinfection manual?
Many netizens asked me privately whether the car air conditioner can effectively isolate the virus. The answer I give you is: it depends on the purification function of the air conditioner and the material of the air conditioner filter.
Many car manufacturers have added air purification systems to their cars, including PM2.5 filtration, AQS, CLEANZONE and so on. If your car has this function, please open it. The materials of air-conditioning filter elements can be roughly divided into these categories: pure non-woven fabrics, bamboo fibers, cold catalysts, activated carbon, nano-mineral crystals and Hyman Pu. Except for the first two kinds, most of them are filtered with HEPA filter paper.
HEPA filter can filter 0.3 micron particles. Please refer to the above table for the specific filtering effect. If your air filter reaches the grade standard of E 1 1, it is equivalent to your car wearing a N95 mask. Let's put it another way. The purpose of wearing a mask is to prevent the droplets sprayed when coughing and sneezing from touching your mouth and causing mucosal infection. There is a problem with these water droplets. The answer is: 82% of the size is concentrated in 0.74 ~ 2. 12 micron. E 1 1 filter element /N95 mask, which can filter 0.3 micron and the filtering effect is over 95%, can be said to be very safe.
If the filtration grade of your car air conditioner can't reach the standard of E 1 1, Komura suggests that you try not to circulate outside in places with many people and poor air circulation, and try to use internal circulation. If you drive to a place with few people and good air circulation, you can open the external circulation and open the skylight/window to ventilate the car.
In addition to ventilation in the car, disinfection in the car is also inevitable. Let me briefly tell you how to correctly use the types of disinfectants and the proportion of disinfectants.
First of all, disinfect as many places as possible that we often contact, such as door handles, seat belt interfaces, steering wheels, function buttons in the car, gear levers, etc. It is recommended that you wipe the door handle with 75% alcohol. The reason why 84 disinfectant is not recommended is because the common door handles are made of metal, and the use of 84 disinfectant may cause chemical reaction and corrosion, thus damaging the car. Moreover, the sterilization speed of alcohol will be faster than that of 84 disinfectant, and 84 disinfectant will have a killing process.
Intelligence 3: Is the service true?
Some netizens will ask, "Xiao Cun, what should I do if my car needs maintenance or repair?" At this time, please don't worry, don't drive to the 4S shop by yourself. This question is the third information card saved for you.
According to many years' experience in visiting shops in Xiaocun, many 4S shops have supported services such as door-to-door car picking-up, door-to-door car picking-up, booking online quotation, payment for maintenance customers, and even said that they can renew their insurance remotely by providing driving license and ID card photos. For everyone's health and safety, don't blindly run 4S stores. If you have anything, please contact the store as soon as possible. Usually, the store will arrange a special service manager for you.
If you are still in the stage of car selection, Xiaocun recommends that you use car home online VR to see cars. Just search for the car series you want to see and click Panorama to see the car. As for the in-store terminal concessions and brand services of 4S stores, on the one hand, you can refer to the owner's price channel, on the other hand, you can also pay attention to the car number of 4S intelligence bureau. The village will bring you continuous new car-to-store consultation, and maybe there are models you like, not to mention exclusive discounts for fans!
As the time for returning to work is just around the corner, Xiaocun also saw a news on the Internet that he was infected by queuing to buy roast duck. I also hope that everyone can always protect themselves and remember the anti-virus manual. In addition, we have to promise the village one thing, that is, after the epidemic is over, none of us will laugh at who is fat, okay?
