The most basic way for us to distinguish COVID-19 patients is to measure their body temperature and observe whether they have cough and fever. If you have symptoms such as fever, you can judge the suspected COVID-19 virus infection, and then pass the nucleic acid test. If the test is positive, you can be diagnosed with COVID-19's disease.
However, some people infected with COVID-19 virus are asymptomatic. They have no symptoms, no fever or cough, and their temperature tests have been normal. But they are contagious and can spread the virus to others.
If there are asymptomatic cases, it means that people who have close contact with him are very dangerous. Even they can't realize that they have been in contact with COVID-19 virus carriers.
The news media reported that a woman herself was infected with COVID-19 virus, but she had no symptoms. But she was still contagious, infecting the whole family. It was not until the final nucleic acid test that she realized that she was the source.
However, asymptomatic infected people are not the most terrible. What is even more frightening is that treating discharged cases is not 100% safe.
Take Guangzhou as an example, there have been 1 1 cases in recent days. After discharge, COVID-19 patients who tested positive again had to be hospitalized again for treatment.
Previously, we have always advocated that after COVID-19 patients are cured and discharged from hospital, if conditions permit, they can donate plasma to extract antibodies from it to help other patients fight the virus. If these plasmas are mixed with the blood of people who have recovered from yang disease, and this abnormality is not detected in time and effectively during plasma testing, then
If there is a recurrence of Yang, the report that patients who have been cured and discharged will donate plasma will be slightly delayed. Of course, when using plasma, various blood tests are definitely available, so users don't have to worry too much.
