Is five days of COVID isolation enough? New study has some answers

When the Centers for Disease Control and Prevention (CDC) said in January it was shifting its recommended isolation period for people infected with COVID-19 from 10 days down to five days, followed by five days of mask-wearing, there were some concerns or questions about whether five days of isolation was too short. In the pandemic's early days, the CDC had started out recommending 10 days of isolation and 14 days of quarantine, so five days seemed like a significant reduction.
