In this March 18, 2020 photo, Nilu Asca, a 24-year-old single mother, struggles to pull a stroller holding her 2-year-old daughter Darleth up a flight of stairs, inside a building nicknamed "Luriganchito" after the country's most populous prison, in Lima, Peru. Darleth has been diagnosed with hip dysplasia and must wear a spica cast. She and her mother are one of 44 families who reside in one of the small rooms of the deteriorating building, just a few blocks from the presidential palace. (AP Photo/Rodrigo Abd)
