This is an excellent question. Alongside other safety measures, regular (ie. twice a week) pro-active screening for COVID-19 will still be an important part of reopening more of society so we can all get back to what we’ve been missing sooner.

By being proactive with screening we can help make shared spaces safer, reducing the necessity for cyclical lockdowns, and helping us fight a virus that is mutating everyday. Regular testing will allow business to re-open safely, keeping staff safe, happier, more productive.
