Discharged coronavirus patients here no longer have viable virus and will not spread disease: NCID
SINGAPORE - The 62 Covid-19 patients who have been discharged here no longer have the virus in them and cannot pass the infection on to others, experts at the National Centre for Infectious Diseases ( NCID ) assured.. Read more at straitstimes.com.
Stories have surfaced in China that one in seven patients who has recovered is still infectious.But the situation here is very different.Professor Leo Yee Sin, executive director of NCID, said doctors monitor virus-shedding in patients' respiratory tract - in other words, they check if the patient is still releasing live virus and thus remains contagious.
This is done by taking nasal or throat swabs.Virus-shedding stops if the patient no longer has the virus in him."Patients are only discharged when they have clinically recovered and molecular testing indicates they have stopped shedding the virus," she said.
This means that should they sneeze or cough, there is no virus from them that could contaminate surfaces or infect others.Many of the hospitalised patients here are feeling well, especially during the last few days of their hospital stay.But keeping track of virus-shedding is a precaution Singapore has taken.
Prof Leo said when tests show that patients are completely cured and no longer have the virus in them, they are still kept in the hospital for at least another day waiting for the results of a second test done 24 hours after they have received the first all-clear results.
Beyond that, she added:"Cases who are discharged are reviewed at our clinic."Dr Li Yueping, director of the intensive care unit at China's Guangzhou No.8 People's Hospital, had said that test results of 14 per cent of its patients who had been discharged returned to positive when they went for follow-up checks.
Dr Shawn Vasoo, clinical director of the NCID, said this is not surprising - nor is it worrying.The virus was found in anal swabs.He said data from the Sars (severe acute respiratory syndrome) outbreak in 2003 found virus in patients' stool for about four weeks after they had recovered.
But this does not mean the virus is still viable, he said, adding that the coronavirus is spread through droplets."As infection is spread by respiratory droplets, if (viable) virus-shedding is absent from respiratory secretions, then these people should not go on to infect others," Dr Vasoo said.
Furthermore, he said, even if the virus in the stool is still active, it"should not be a source of transmission with modern sanitation and hygiene being observed".On whether these discharged patients can be infected again by the coronavirus - as Osaka's prefectural government said had happened to one of its earlier patients, a female tour bus guide - Dr Vasoo said doctors currently do not know how long patients remain immune to the disease.
"We need to study the immune response of patients infected with the Covid-19 virus. At the moment it is unknown if patients infected by the Covid-19 will have long-lasting immunity to the virus," he said.

Nothing is impossible.. 🙏🙏 Not according to a few studies. Dangerous to assume no more risk without testing. Japan (and others) have yet to confirm if discharged patients (by lab tests) were tested positive again because of reinfection or relapse. Nasal swabs are not 100% sensitive to lower respiratory tract infections like Covid-19
Coronavirus: Virus' spread puts a question mark over fate of the Tokyo OlympicsTOKYO (BLOOMBERG) - The Tokyo 2020 Olympics are less than five months away - or, in coronavirus time, somewhere between six and 10 incubation periods. Even as organisers at every level insist the Games are not at risk, the rapid spread of Covid-19 cases in Japan is already casting a chill over the event.. Read more at straitstimes.com.
