Prof. Dr. Yong Phuworawan, Head of the Center specializes in clinical virology. Department of Pediatrics Faculty of Medicine Chulalongkorn University Post a message via Facebook saying how long should covid 19 patients prevent the infection from infecting others?
There are many patients at this stage. How many days will the time to keep someone infected with COVID-19 or prevent infection to others? Therefore, there is a question whether How many days will it take? which is considered the period of infection
The study was published in two journals, the JAMA Journal of the American Medical Association and the New England Journal of Medicine, the world’s leading journal. by looking at the culture If the virus is alive, it can be cultured and grown in cell cultures. shows that the infection can still be spread
from the two journal studies have a very similar effect. is that the infection will decrease after 7 days and will be found very rarely after 10 days since the onset of symptoms
During this time, whether those who are infected with symptoms or have few or no symptoms The duration is still the same. but the viral load and the percentage of detection in those with mild symptoms is less common.
The same is true for those who have been vaccinated or not vaccinated. The duration of transmission of infection is no different. It’s just different in the amount of virus. And the detection rate in those who have been vaccinated is lower, but the duration is still 10 days. Ask permission to take photos from the journal to see.
Therefore, in those who are infected You should quarantine and protect yourself for at least 10 days to be considered safe. but for some When the symptoms have improved, let’s say 7 days that you have to stay at home and allow 3 days after going out, you must always be aware that We can still infect others. must protect himself fully not to infect others at least 10 days
In most ATK tests, ATK is positive, followed by culture. But we wouldn’t take the ATK result to determine if ATK is negative and won’t spread the infection because the ATK test results are less sensitive. And the results can have false positives or false negatives. In practice, the infected There is no need to double check ATK, it wastes resources. Because whether it’s positive or negative We will have to prevent the spread of infection for 10 days anyway.
