Around 40 per cent of the people tested positive for COVID-19 in the United States were asymptomatic, according to the country’s Centers for Disease Control and Prevention (CDC).

The revelation was made on Sunday in the CDC’s latest “COVID-19 Pandemic Planning Scenarios” document.

The document, which the agency said could be used to estimate the possible effects of COVID-19 in the US states and localities, was first posted on May 20.

The latest update is based on data received by the CDC through June 29.

The new percentage of infections that are asymptomatic, under the CDC’s “current best estimate”, is up from the 35 per cent the agency estimated on May 20.

Also, under the agency’s current best estimate, an asymptomatic individual is 75 per cent as infectious as a symptomatic individual.

“Asymptomatic cases are challenging to identify because individuals do not know they are infected unless they are tested, which is typically only done systematically as a part of a scientific study,” the CDC added.
