As countries begin to ramp up testing over the spread of the novel coronavirus, new data is suggesting that asymptomatic people — those who test positive for the disease caused by the virus but don’t show symptoms — are helping to circulate COVID-19.
As a result, some are beginning to ask: should everyone be wearing more personal protective equipment (PPE), such as face masks, in their day-to-day lives in order to prevent the virus from spreading, even if they appear healthy?
A report by Singaporean researchers published by the U.S. Centers for Disease Control and Prevention (CDC) estimated that around 10 per cent of new infections are being spread by either healthy-looking, asymptomatic people or people who have yet to develop the disease’s flu-like symptoms.
During an interview with NPR on Tuesday, the director of the CDC also said as much as 25 per cent of all U.S. cases remained asymptomatic — a figure that could be as high as 54,000 among the 216,000 cases the country reported as of Wednesday.
