Nearly every day, 77-year-old Surin Makradee goes door-to-door in her village in Thailand, visiting every home to check people's temperatures in a routine repeated in communities across the country during the coronavirus pandemic.
"I consider people in the village my family. If I don't educate them, they will not understand the risk of getting infected," Surin said in her village of Saladang in Ang Thong province, about 90 km (55 miles) north of Bangkok.
She is a member of the Village Health Volunteers, a long-overlooked network of more than 1 million community workers dating back to a Cold War-era hearts-and-minds program.
