COVID-19 may * * * for a long time, so why didn't the SARS virus * * * for a long time?

The existence of viruses requires a suitable environment, and viruses cannot survive at too high a temperature. So when summer comes, the SARS virus will fade away, and COVID-19 can be said to be a variant after the SARS virus. It is very similar to SARS virus, but its characteristics are different. It has a wide spread and slightly lower lethality. Therefore, as far as reporting is concerned, the audience in COVID-19 is far more than the SARS virus. The virus is mutated, and its mutation direction is in a direction that is easier to survive. So after a long time, it may mutate into a less deadly flu.

It is precisely because the single-stranded virus has such a powerful mutant that it is not easy to develop drugs. When a specific drug is made, the virus will immediately adapt to the mutation, and then form a virus with greater lethality, which is not conducive to the rescue of patients. Therefore, if drugs are used to block the virus, it is best to use vaccines, but the research and development of virus vaccines is not easy. Historically, we have only successfully repelled smallpox with vaccines, but smallpox is a virus that has existed for a long time, so its lethality is much stronger than that of COVID-19.

Now, we can only hope that COVID-19 will disappear as soon as possible like SARS, because the outbreak of the virus has affected the world economy. Especially in our country, our country has stopped working for two months now, which has caused great economic losses. Although it is now advocated to return to work partially, the obstacles to return to work are very great because most urban communities are closed. And after staying at home for so long, people will have some psychological problems more or less.

However, since the virus has spread to the world, it will definitely not return to work in a short time. At this time, we should improve our psychology and ensure our physical and mental health. Don't think so much, wait for a full return to work.
