The coronavirus disease (COVID-19) survivor Santiaga Cerrato, 85, who suffers from Alzheimer’s disease, gets hugged by her son Enrique Suarez at the nursing home Centro Casaverde in Navalcarnero, outside Madrid, Spain, December 23, 2020. Under the Madrid region's coronavirus restrictions elderly residents like Santiaga are allowed to visit family over the holidays if they have coronavirus antibodies that can guarantee their immunity to the disease. Cerrato will have to undergo diagnostic and antibodies tests prior to going back to the nursing home to determine whether she must observe a quarantine period upon her return.
