The workers who now find themselves on the frontlines of the COVID-19 pandemic have always been essential but we're just now noticing them. A worldwide health crisis forced us to realize that we depended on them—and that they're risking their lives. With the streets empty and much nonessential work stopped, we are finally seeing the faces of the people we need to survive.

Photographers also perform essential work, by showing us people we might not otherwise see—the fumigators working at night in Nairobi and the garbage collectors driving dark streets in Normandy. In South Africa, a photographer notices workers returning electricity to a poor neighborhood, while in Brazil, another finds a shopkeeper delivering groceries to his customers.
