FILE -- In this March 20, 2020 file photo, a senior citizen peers from his window through a web of electric wires in the Rocinha slum of Rio de Janeiro, Brazil, amid orders to stay home to contain the spread of the coronavirus. In Rocinha, narrow alleyways reduce airflow around homes packed tightly together; clean water is scarce, sewage often runs in the streets and winding alleys and soaring staircases make it difficult for medical professionals to retrieve an ailing patient in case of emergency.
