Patients with coronavirus cease to be infectious after 11 days after the onset of symptoms of the disease. It is reported RIA Novosti with reference to the Singaporean scientists.
According to their estimates, tests of the patients coming to the amendment, can show the presence of coronavirus, but it is already not dangerous. Scientists explained that the tests are not able to establish the viability of the coronavirus and the possibility of its transmission to others — they reveal only part of the genome.
It is emphasized that, in theory, about 11 days, there are exceptions — for example, patients with cancer undergoing chemotherapy.
Currently, the patient after treatment of the disease caused by a coronavirus, can be discharged from hospital only after two negative tests.
Previously, scientists said that the virus SARS-CoV-2, calling the disease COVID-19, has a very high level of infectiousness due to the fact that combines the genomes of other coronaviruses. The authors of the relevant studies have established that the genome of the new coronavirus in 96 percent of the genome of the SARS virus — SARS-CoV-1, which in 2003 claimed the lives of 774 people. While SARS-CoV-2 has characteristics of a benign human coronavirus HCoV-HKU1.
