Royals Prince Charles Has Never Looked So Happy to Be Back to Work — See the Excited Royal in Action Queen Elizabeth's son, who has recovered from coronavirus, thanked workers who kept the London Underground running throughout the pandemic By Stephanie Petit Stephanie Petit Stephanie Petit is a Royals Writer and Reporter at PEOPLE. People Editorial Guidelines Published on July 2, 2020 04:34 PM Share Tweet Pin Email Royal outings may look different post-coronavirus, but Prince Charles is happy to be back to work! Queen Elizabeth's eldest son and heir, 71, stepped out on Thursday to meet key workers from Transport for London who have worked throughout the COVID-19 pandemic. Charles rolled down the car window and flashed a huge smile as he left the engagement, where he told staff who kept the London Underground running, "I don't know how you do it." Throughout the visit, the royal — who contracted a mild case of coronavirus in March — and the workers practiced safe social distancing and greeted each other with "namastes" rather than formal handshakes. Prince Charles was in equally high spirits on Wednesday, when he found himself surrounded by farm animals — including adorable piglets — during his visit to celebrity farmer Adam Henson's Cotsworld Farm Park to promote rural tourism in the U.K. Prince William and Prince Charles Embrace in Newly Released Photo to Celebrate Father's Day Prince Charles.

They visited the Gloucestershire Royal Hospital on June 16 to express their thanks for keeping the healthcare and its emergency services going throughout the crisis. After months of isolating at their home in the Scottish Highlands, the couple have returned to their London home, Clarence House, and resumed royal engagements, including hosting President of the French Republic Emmanuel Macron for a special occasion: the 80th anniversary of Charles de Gaulle's "Appel," or broadcast to occupied France after the Nazi invasion in 1940.

"He did speak of his personal experience, so first-hand experience for him," health care assistant Jeff Wall said. "He also spoke about his loss of smell and taste and, sort of, still felt he's still got it now."

However, Queen Elizabeth, 94, will unlikely to be seen outside of palace walls for many months, leading some to speculate that she will not step out for an official public duty until the fall at the earliest. A royal source told the U.K. paper The Sunday Times, "The Queen won’t do anything which goes against the advice of people in her [age] category, and she's going to take all the appropriate advice. There are discussions what we could do and couldn’t do come October." Can't get enough of PEOPLE's Royals coverage?
