Researchers have found that those with and without symptoms are equally likely to transmit the SARS-CoV-2 coronavirus, according to a new study published in JAMA Internal Medicine.

Key Facts:

~ South Korean scientists analyzed samples taken from 303 people isolated at a community treatment centre who had tested positive for the coronavirus between March 6 and 26.

~ Of the 303, 193 were symptomatic when they were isolated and 110 were asymptomatic, and researchers found that the viral loads (the amount of virus in an infected person) were very similar in both types of patients.

~ They found roughly the same amounts of SARS-CoV-2 virus in the noses, mouths and lungs of asymptomatic COVID-19 patients as they did in others with cough and fever.

~ Researchers suggest that infected people should be isolated regardless of how weak or severely the external symptoms of COVID-19 manifest.

~ The study offers evidence in the consequential debate about how contagious asymptomatic COVID-19 patients really are.

~ Currently, most health experts working around COVID-19 are doing so with the notion that symptomatic people are more contagious. Asymptomatic people with COVID-19 are just as contagious as those showing symptoms.

~ This finding can have important consequences in guidelines and policymaking around COVID-19 transmission and prevention.
