Patients are then able to transmit the bug for between seven and ten days after they begin feeling ill.
However, the experts found that the new coronavirus “could not be isolated or cultured after day 11”, reports The New York Post.
The scientists from Singapore's National Center for Infectious Diseases and the Academy of Medicine studied 73 people who were suffering from Covid-19.
Patients who still displayed symptoms after 14 days could be picking up parts of the respiratory disease that cannot be passed to others.
BATTLE TO BEAT THE BUG
The researchers wrote: 'Based on the accumulated data since the start of the COVID-19 pandemic, the infectious period of (coronavirus) in symptomatic individuals may begin around two days before the onset of symptoms, and persists for about seven to ten days after the onset of symptoms.”
They continued: “Active viral replication drops quickly after the first week and viable virus was not found after the second week of illness.”
It is hoped the study could help doctors figure out when to send patients home easing pressure on packed hospitals around the world.
The bug first jumped from animals to humans in Wuhan, China, late last year.
It has since spread across the planet killing more than 344,000 people and infecting over 5.3 million.
In the UK, a total of 36,793 victims have died due to the disease after a further 118 deaths were confirmed on Saturday.
