Is it really healthy to have a health code

Not necessarily really healthy. At present, health codes are analyzed by self-reported data, which is not real-time and dynamic, but a relatively fixed data. Therefore, it is entirely possible that people have been infected with COVID-19 virus because of the information lag, but the health code is still valid.

For example, I have a friend who is a drip driver. He goes in and out of high-speed railway station, airports and other crowded places every day. These people may come from all over the country. If there is an epidemic somewhere, he doesn't realize that he has been exposed to suspected infected people, so naturally he won't take measures such as isolation and nucleic acid testing.

Secondly, the current health code only analyzes whether COVID-19 is infected, and it is not true that healthy people have health codes. For example, a dying patient may not be infected with COVID-19 virus, but his health is not healthy. However, because he is in the hospital every day and has few contacts, the system thinks he is healthy.

Therefore, in daily life, we still need to do personal protection to avoid being infected with COVID-19 virus due to carelessness. For example, daily travel, taking public transportation, or wearing a mask. For example, when you come back from going out, take care of your clothes first, then spray alcohol for disinfection and wash your hands. As long as these protective works are done in place, even if you really come into contact with suspected infected people, you can effectively protect your personal safety.

In fact, the health code helps us to screen out those who may have had contact with COVID-19 virus carriers, and collect, analyze and process these population data in the form of big data for us to see? Unhealthy? what's up Virus carrier? At the same time, accurate reactions can be made in the first time, such as separation, such as nucleic acid detection and confirmation. This can protect more people.
