Thessaloniki, Greece, stringer Costas Kantouris dug behind the scenes to reveal the extraordinary lengths one man went to in caring for his COVID-19-stricken mother-in-law and other relatives — the nurse created an intensive care unit in his home.

Kantouris won the international competition to track down the man whose feat had begun to appear in local media reports. He interviewed nurse Gabriel Tachtatzoglou, delving into his motivations and methods for taking on the high-risk endeavor. Tachtatzoglou had spared his family members from hospitalization in an overburdened local facility while simultaneously easing the patient load in Greece’s most heavily affected region, where ICUs were already at capacity.

Visuals were a challenge as the makeshift ICU was dismantled when the family recovered, but photo stringer Giannis Papanikos complemented the story with a visit to the home for a portrait shoot. Athens staffer Derek Gatopoulos drafted this installment of AP’s “One Good Thing” series, which was picked up even by the Greek press.
