COVID-19 patients do not pose a threat of spreading the disease after 11 days, according to a joint study conducted by the National Centre for Infectious Diseases (NCID) and the Chapter of Infectious Disease Physicians, Academy of Medicine, Singapore.

Key insights:

• “In a local study from a multicenter cohort of 73 COVID-19 patients, when the Ct value was 30 or higher (i.e. when viral load is low), no viable virus (based on being able to culture the virus) has been found,” the study stated.

• “In addition, the virus could not be isolated or cultured after day 11 of illness,” it added.

• “Based on the accumulated data since the start of the COVID-19 pandemic, the infectious period of SARS-CoV-2 in symptomatic individuals may begin around 2 days before the onset of symptoms, and persists for about 7 – 10 days after the onset of symptoms,” the study said.

• It also stated that active viral replication drops quickly after the first week and a viable virus was not found after the second week of illness despite the persistence of PCR detection of RNA.

This is a very significant article,and the first study which backs quarantine and isolation policy. On the basis of this article,we can now see that post 14 days,the virus might not sustain in asymptomatic individuals.
