Coronavirus Patients Are Not Infectious 11 Days After Getting Sick: Study


With many concerned about a second wave of coronavirus infections, a new study suggests there may not be reason to worry. Patients of COVID-19 are reportedly not infectious 11 days after getting sick.

A study out of Singapore reads, "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. In addition, virus could not be isolated or cultured after day 11 of illness."

They also referenced a German study which found that the degree of the virus was much higher in the first week of symptoms, supporting their 11-day theory.

The study also reveals that patients may begin being infectious two days before they start showing symptoms. "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 reads.

Additionally, Singapore has had fewer cases of coronavirus compared to other countries around the world. With 32,433 cases according to data compiled by Johns Hopkins University, only 23 deaths were reported.

More than 5.51 million coronavirus cases have been reported worldwide.
