After reading some news about the situation of coronavirus in Europe and US, as a Chinese, I'm more and more worried, and I am afraid that some information you guys get from media is not true or not completed, so I would like to give you some correct information and suggestions. 1. The new virus is not very dangerous, only 20% will become serious and the rest can cure themselves, only weak people and old people need to worry. -- Very Misleading!!! In fact, the virus is very dangerous, if one is infected and becomes serious, the lung will be permanently hurt and it's capacity will be less than 50% of the normal standard. And if one was not treated correctly when the symptoms were still not serious, there's a remarkable chance that he will become serious, and one is very likely to die if he becomes serious but still have not been cured in a hospital, even if he is young and healthy. For example, the famous young doctor Li, who warned people at the beginning but died, he was only 35. (In China, we still DON'T KNOW how many people died in Wuhan city because of this virus, many of them died at home and are not calculated as victims.) 2. People don't need a mask and can even go to party freely, only need to wash hands. --WRONG!!! The virus is so easy to spread that one can be infected in seconds when he faces a patient. And mask is always the most effective way to protect one from the new coronavirus, and people should always wear a mask when they go to a small room and face or talk to another people who is in less than 2 meters. So you can drive without a mask, you can go out for a walk without a mask, but you really DO need a mask when you are in a crowd or meet with strangers (for example, in a public elevator). And if possible, don't go to any party, and better don't travel. (especially when you will have Easters next month) 3. The virus will not be spread if the patient is not serious. -- WRONG!!! Many patient spread the virus when they still feel well, they may thought it was only a flu or just caught a cold or even didn’t feel anything and had no symptoms, but other people can still be infected. So if one is found fever after he travelled or went to a party or meet with some people who just comes back from Italy or something like that, he should stop working at once and stay at home alone(this is important, if you don't want to do harm to your families), and people who has contacted him closely should be very careful as well. I don't know you will listen to me or not, or maybe it's just too late, but I think I must say something to you. I don't believe any gods but I do believe one should do something to help others when he still can in a world-wide crisis like this. I hope you and your families will all stay well. Edit: It seems that situation is getting worse in Europe and US, so I would like to add some typical symptoms which may help you. If one is infected by this virus, he is very likely to have some or all of these symptoms in 7-14 days. 1. Dry cough, 2. Fever over 37.3 degree， 3. Difficulties while breathing (very important!) 4. Feeling tired or powerless for no reason 5. Loss of taste (mostly reported from Japan) May this of no use, and don't forgot the famous saying from Trump, "That's a very good chance that you are not gonna die." That is true, but still, keep safe distance from people.
