COVID-19 epidemic prevention strategy-1
On March 26, 2020, the UK Society of Chinese Automotive Engineers (UKCSAE) invited Dr. Nie Nixuan from Wuchang Hospital to provide online science education and answer questions about the novel coronavirus (COVID-19). Dr. Nie combined his experience in responding to the outbreak in Wuhan and gave an easy-to-understand explanation of the 'Seventh Edition of Diagnosis and Treatment Plan' based on cases, and also compiled a note to share with everyone. The coronavirus should be taken seriously, but if you know yourself and your enemy, it is not something to panic about.
way for spreading
Respiratory droplet transmission
Wear a mask, a medical disposable mask is enough. Use your elbows to cover your mouth and nose when sneezing to avoid close face-to-face contact with others. You can hold your breath for a few seconds when others sneeze.
Wear goggles (optional) to avoid other people’s saliva splashing, just wear glasses.
When eating out, sit alone at a single table, avoid gathering face to face with others, and avoid talking while eating.
spread by close contact
Avoid direct contact with public places such as door handles and elevator buttons, and use paper towels to isolate them. If you come into direct contact with your hands, avoid rubbing your eyes, mouth, nose, and ears. Wash your hands or disinfect your hands with sanitizer.
Try not to touch anything outside directly with your hands. You can use disposable gloves or spray disinfectant before touching.
Go home, change all your clothes, wash your hair and take a shower. Spray alcohol or disinfectant on the bottom of the shoes and place them in a ventilated place outside the door. Spray disinfectant on the clothes and hang them in a ventilated place, or use ultraviolet light to disinfect them for more than half an hour.
All items brought home from outside should be sprayed with disinfectant before being brought into the home. Cook food, do not eat it raw.
Aerosol transmission in closed environments
Mainly, closed places such as hospital wards where the virus gathers in high concentrations are prone to infection if exposed for a long time. The chance of infection is low in confined spaces such as elevators, so just wear a mask and avoid direct contact. Please open windows for ventilation at home.
The impact of feces, urine, etc. on the environment causes aerosol transmission
Pay attention to the hygiene of public toilets. Try not to use it in contact with it
Disinfectant: It is recommended to use 75% alcohol. The proportion of 84 disinfectant should be used strictly in accordance with the instructions. Do not put disinfectant in the car to avoid high temperature and fire.
In short, be sure to wear a mask when going out, wash hands frequently, and avoid crowd gatherings .

Q&A
Q: Do people who recover from infection develop antibodies?
A: People who have fully recovered will produce certain antibodies and will not be infected for a period of time.
Q: If I hear an unknown cough in my yard, can I still open the window for ventilation?
A: It is very important to open windows for ventilation. We should develop the habit of opening windows for ventilation every day.
Q: Is it safe to order takeout? How to pick up express delivery safely?

A: Wear a mask, especially in supermarkets with central air-conditioning systems. Reduce touching, refer to 'Close Contact Transmission'.
Q: Is there a better way to recycle masks? Oven at 60°C, dry for 40 minutes
A: Poor temperature control may damage the mask material. You can put the mask in a ventilated place to dry and ventilate. If you have multiple masks, you can dry one and use one to achieve circulation.
