Dr. Kim Sang-il, president of H Plus Yangji Hospital in Seoul, is one of the doctors fighting COVID-19 in South Korea. Dr. Kim and his team have gradually improved the efficiency of detecting COVID-19 patients using a new method called "single infection safety treatment booth," which can detect 70-80 patients in an eight-hour shift – 10 times over the traditional way. This method is being implemented in more than 20 hospitals in South Korea, helping doctors save more time and lives.
