Among them, Harbin and other cities have even introduced traffic control measures. For friends who don't have private cars or a limited number, public transportation is the most used and contacted, and it is also the most important thing to pay attention to when riding.
We have explained the disinfection of private cars with examples before. This time, I will explain some points that passengers should pay attention to when taking public transport. First of all, I combine the research results of some authoritative institutions and personnel on coronavirus to do popular science.
The main route of transmission:

Respiratory droplet transmission and contact transmission. Including saliva droplets and sneezing droplets, can be infected by contact with nasal mucosa, oral mucosa or eyes. Contact transmission includes that the virus is deposited on the surface of an object, and then the mucosal tissue is polluted again after being touched by hands, and then the virus is infected. At present, the fastest infection is a man in Zhejiang, who has only been in contact with the infected person for 15 seconds.
Virus survival time:

According to Jiang Rongmeng, a member of the expert group of the National Health and Wellness Committee, the virus can survive for several hours on the surface of smooth objects, and it can survive for up to 5 days at the right temperature and humidity. At present, viral nucleic acid has been found on the door handle of Guangzhou coronavirus patients' home, and there may be live virus, indicating that there is still the risk of infection after exposure for a certain period of time.
How to avoid infection to the greatest extent when taking public transport?
First of all, the first step of prevention is to wear a mask that meets the epidemic prevention standards. And if you take a bus, the carriage is one of the places with the worst air circulation environment, so be sure to wear a mask correctly.
See Appendix A (normative appendix) of Technical Specification for Hospital Isolation: How to wear a mask;
(1) Nose clip side up, dark face outward (or folded down) (2)? Open the folds up and down and let the mask cover your mouth, nose and chin. (3)? Press the fingertips of both hands slowly inward along the metal strip of the bridge of the nose from the middle to both sides until they are close to the bridge of the nose. (4)? Adjust the mask properly so that the periphery of the mask fits the face completely. If possible, you can wear glasses for eye isolation.
Matters needing attention in riding
(Notification source: Dongyang Epidemic Prevention and Control Work Command)
Buses are the means of transportation with the largest traffic volume on the road, and can carry thousands of passengers every day. There is no ventilation in the car. If there is a virus, the concentration will be high and it will infect many people. At present, bus drivers in some areas have been infected with COVID-19 virus, which is the most likely place for the virus to spread. And the place where we contact the bus is also the concentration of virus residues.
Standing handrail:
The standing handrail of the bus is the place where the whole car is most frequently contacted and most people are there, and we all know that the surface of the handrail is mostly smooth, and all kinds of people will hold the handrail tightly, which is one of the "high-risk" parts that are most likely to come into contact with the virus.
Seat armrest:
There are two handrails on the back of the bus seat, which can be grasped by both the back passengers and the standing passengers, and if the back passengers sneeze without wearing masks, there may be droplets with viruses. Of course, for me personally, it is not recommended to take bus lines with large traffic during epidemic prevention.
Matters needing attention in taxi network about car

The most unsafe places for taxis and internet taxis are the narrow space inside the car, higher virus concentration, easier droplet transmission and concentrated necessary contact parts. At present, drip drivers and taxi drivers in some areas have been infected, and there is also a risk of infection if they travel by car. Therefore, if you take the bus, you must pay special attention to the following parts and try not to touch them directly with your hands.
Door handle:
As long as you get on and off the bus, the door handle is the first place you will encounter, and it is also the place you will inevitably encounter. Taxi carries dozens of passengers every day, and it has high touch frequency and smooth handle surface, which is suitable for virus survival.
Door handle:
When you get on the bus, you should close the door. The second place to touch is the door handle. And after closing the door, many passengers have the habit of holding the handle with their hands. Its touch frequency is higher than the handle, and the probability of infection is higher.
Seat belts:
Step 3 after getting on the bus, fasten your seat belt and fasten your seat belt buckle. Because the seat belt buckle is not easy to buckle, the contact area is relatively wide, and the seat belt will be pulled by hand. If you have germs on your hand, it will rub against the safe drops, so it is also a dangerous area for contact with the virus.
Window button:
For passengers, if they want to open the window for air, the fourth position to touch is the window up and down button. Although the contact frequency is not high, there is still a certain risk of contact infection.
The above four parts are the parts that we must contact when taking public transport, and they are also the most susceptible to infection, so my suggestion is to wear gloves or bring your own paper towels, which is the most effective way to isolate the above parts directly.
At the same time, when riding, you can ask the driver to open the external circulation in an open place and open a gap in the window to keep the air in the car circulating all the time, thus reducing the risk of droplet transmission.
Summary:
Academician Zhong Nanshan said in the press conference on February 2nd that there will be a peak in the next 10 days or two weeks, that is, the node of return and rework. This requires all of us in Qi Xin to work together, try not to go out, pay attention to protection when reworking, and protect ourselves and others. I hope everyone will forward this article to friends and relatives at home. At this critical moment, it is the greatest responsibility for yourself and people around you to do a good job in epidemic prevention by car. Of course, if conditions permit, try to travel at the wrong peak and avoid the peak period.
