LIVONIA, Michigan (AP) — At a convent near Detroit, 13 nuns have died of COVID-19. The toll is seven at a center for Maryknoll sisters in New York, and six at a Wisconsin convent that serves nuns with fading memories. Each community perseveres, though strict social-distancing rules have made communal solidarity a challenge as the losses are mourned. Only small, private funeral services were permitted as the death toll mounted in April and May at the Felician Sisters convent in Livonia, Michigan. For weeks the nuns went without Mass and dined in shifts, one per table. Those restrictions have eased in recent weeks as regular activities slowly resume.
