Dr. Joseph Varon, 58, the chief medical officer at United Memorial Medical Center (UMMC), and a team of healthcare workers perform CPR on a COVID-19 patient at UMMC, during the coronavirus disease (COVID-19) outbreak, in Houston, Texas, U.S., July 17, 2020. Reuters photographer Callaghan O'Hare: "Houston's COVID-19 cases had been rising for weeks and it was my third time photographing patients in the intensive care unit. I was following Doctor Varon and his team as they intubated two patients with worsening conditions. The first intubation went smoothly. We walked into the second patient's room and almost as soon as they began the procedure, his heart rate dropped. The air was filled with anxiety. I was in a corner of the room with my camera and it wasn't until two medical students jumped onto the bed and began administering chest compressions that I realized the patient was dying. The whole scene took place over the course of thirty minutes as we all nervously watched the clock and his heart rate monitor. Although this patient was surrounded by people while he died, they were faceless doctors in hazmat suits. He wasn't able to say goodbye to his family, friends, and the people who cared about him. I looked him up later on Facebook, and his profile picture had a filter on it that said, "I'm an essential worker, I can't stay home." I often think about him and the likelihood that he contracted the coronavirus at work. I hope his image and his story resonate with people and show why it's important to wear a mask and stay at home to protect those that can't."

A migrant carries her belongings following a fire at the Moria camp for refugees and migrants on the island of Lesbos, Greece, September 9, 2020. Reuters photographer Elias Marcou: "The morning after a fire broke out at Moria refugee camp on Lesbos island in the olive grove next to it, helicopters were dropping water to extinguish scattered fires, while people were returning to assess the extent of the damage and recover what they could. At the time, approximately 13,000 people were living at the camp, making it the most populated in Europe. The night before, the police had blocked the road a few hundred metres from the camp to prevent refugees from walking to the nearest city of Mytilene, while the camp was ablaze, and people were desperately trying to get away from the flames, carrying with them any personal belongings they could gather in the darkness. Exploding cooking gas canisters gave an intensity to the night chaos. In the grey morning, I watched as a woman carrying some blankets turned back for a moment as if to take a last look at the remnants of the life she was once more moving on from. This thought moved me deeply as I captured this image." REUTERS/Elias Marcou/File photo SEARCH "POY STORIES 2020" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES. TPX IMAGES OF THE DAY

Khadjou Sambe, 25, Senegal's first female professional surfer, holds a surf board as she talks to her coach Rhonda Harper, the founder of Black Girls Surf (BGS), a training school for girls and women who want to compete in professional surfing, as Koune Ba, Sambe's mother, watches on at their courtyard, in Ngor, Dakar, Senegal, August 12, 2020. Sambe went to California in 2018 to train with BGS. Harper said she arrived without a cent in her pocket, speaking no English and with a wild, free surf style that needed taming to fit the structure of surf competitions. "It's like trying to take a tornado right, and put a rope around it, wrangle that thing down. Because she is such a dynamic surfer that it's hard." Harper said BGS started looking for female surfers in Africa because of the lack of representation in professional surfing. REUTERS/Zohra Bensemra SEARCH "SENEGALESE WOMEN SURFER" FOR THIS STORY.
