LONDON – The U.K. has launched a nationwide free testing program to diagnose COVID-19 in people who are asymptomatic, in the latest attempt to stem the tide of infection. Through the program, all local authorities will provide rapid testing using lateral flow devices. In addition, companies will be provided with free tests to set up workplace screening. Initially, the focus of both strands will be on getting people who cannot work from home to come forward for regular checks.
