Héctor Perdomo Encarnación sells masks on Avenida Juan Ponce de León, a main thoroughfare in San Juan, Puerto Rico. Before the coronavirus hit Puerto Rico and the government declared a curfew on March 15, Perdomo Encarnación worked in the construction industry. His work was halted to prevent the spread of COVID-19, the disease caused by the coronavirus. Now he sells masks, which his friend makes, Monday through Friday in the San Juan communities of Santurce and Condado.
