How long can mild or asymptomatic coronavirus patients transmit the disease to others? This is the question that medical experts have been working on since the beginning of the epidemic.
A study by Oregon Health and Science University and Oregon State University in the United States suggested that patients with mild or asymptomatic coronavirus transmission could possibly transmit the disease to others within 10 days.
The study, published in the medical journal Infection Control and Hospital Epidemiology, analyzed dozens of research reports and found that the duration of virus transmission or transmission to other patients in Code 19 could vary depending on the severity.
According to research, people who suffer from the severe severity of code 19 can carry the virus for up to 20 days.
Research has shown that the identification of viral RNA has nothing to do with its inactivity.
Researchers say more data is needed on how patients are exposed to the virus in order to determine their risk of spreading the virus.
The experts in the study decided to conduct the analysis to learn more about coronavirus transmission and to help control epidemics.
"Although it can take a long time for people to lose the virus, the research reports we analyzed suggest that infectious or live viruses can be detected in mild or asymptomatic patients for only 9 days."
The study analyzed 77 research reports, 59 of which were published in medical journals.
Traditional methods were used to test for virus loss in all research reports.
At the outset of the outbreak, a study found that people infected with the novice coronavirus were more likely to transmit the virus to other healthy people within the first seven days after contracting the virus. Chances are.
The study by Germany's Handswire Institute of Microbiology, Klinikum München-Schwabing, Charité Universitätsmedizin Berlin and the University Hospital LMU Munich explained why the virus is spreading so easily, as most people would be spreading it at the time. Yes, when the symptoms are mild and the flu is like a cold.
The researchers analyzed several samples from nine people who were being treated at a Munich hospital for mild to moderate seizures.
All of these patients were young or middle-aged and did not suffer from any other disease.
The researchers collected samples of their saliva, blood, urine, mucus and feces at different stages of the infection and then analyzed them.
Patients' throat samples revealed that the virus was most contagious in the first week when it entered a person's body, while blood and urine samples showed no signs of the virus. There was viral NA in the waste.
The researchers said that this is very different from the SARS virus, in which the virus is transmitted in 7 to 10 days, but in the new novel corona virus this process is faster than 5 days and compared to SARS. A thousand times more.
They also found that in people with a high severity, the virus becomes highly contagious by the 10th or 11th day, while in milder patients, the severity gradually decreases after 5 days. It starts to come and on the 10th day these patients may not be able to spread it further.
He said the results showed that if a person had 10 symptoms, he could be discharged from the hospital and kept at home.
