The US's Centres for Disease Control and Prevention (CDC) has updated its guidelines for testing people who do not show symptoms of COVID-19.

Though this is a report from the US, it warrants close attention as we are battling a common enemy. The CDC said that due to the significance of asymptomatic and pre-symptomatic transmission, its guidelines are further reinforcing the need to test asymptomatic people, including close contacts of a person with documented infection.
