Meghan Markle is taking the threat of the coronavirus pandemic very seriously. A source close to the Duchess of Sussex told the Daily Mail that she's become even more cautious in recent days, since news that her father-in-law, Prince Charles, had tested positive for the virus. "Meghan said hearing the news of Prince Charles has put everyone on edge," the source said. "She said she is worried about her own health and Harry's health because she doesn't want to pass anything onto Archie." One of the biggest changes Meghan has made has been to the policies she's enforcing with staff working with her family during the quarantine.
