Researchers from the Academy of Medicine in Singapore and the National Center for Infectious Diseases were among those who they discovered these new findings.
Why don't patients with Coronavirus transmit the infection after 11 days?
The study was performed on 73 patients in Singapore. The researchers found that while patients continued to test positive for coronavirus after 11 days, they could no longer isolate or culture virus samples from these patients.
According to the study, patients with coronavirus become infected two days before they show symptoms and remain infectious for 7 to 10 days after the onset of symptoms.
The rate of virus multiplication slowed after the first week of infection and stopped completely after the second week.
Eleven days after infection, patients experience two significant symptoms: frequent coughing and high fever. However, at this stage the patient can no longer transmit the virus to someone else.
The findings of the new study could lead to changes in the way patients are treated with COVID-19. Most countries for example, they require patients to be negative before they can get out of it quarantine. However, according to a recent study by the Korean CDC, this method of categorizing patients with coronavirus could be wrong.
New discoveries about COVID-19
According to the latest findings, the fact that some patients have more severe symptoms than others is due to immune causes.
In addition, the pharmaceutical industry and biotechnology companies are working to create a vaccine, which they plan to release by the end of this year.
Sunny Xie, a researcher at the Center for Genomics at Beijing University in China, and his team are working on a drug that is expected to be released in late 2020. The researcher said that when the drug was tested on infected mice, it reduced the virus. load, which means it has healing properties.
