Pope Francis shares a word with Msgr. Luis Maria Rodrigo Ewart as he arrives in the Paul VI Hall at the Vatican for his weekly general audience, Wednesday, Oct. 28, 2020. A Vatican official who is a key member of Francis' COVID-19 response commission, Fr. Augusto Zampini, acknowledged Tuesday that at age 83 and with part of his lung removed after an illness in his youth, Francis would be at high risk for complications if he were to become infected. Zampini said he hoped Francis would don a mask at least when he greeted people during the general audience. "We are working on that," he said. (AP Photo/Alessandra Tarantino)
