The image shows a group of children wearing white lab coats and face masks walking down a hallway in a school. The hallway has a green floor and a white wall with a window on the right side. There is a green trash can on the left side of the hallway. The children appear to be of different ages and ethnicities, and they are walking in a line. Some of them are holding hands, while others are looking at something in the distance. It seems like they are participating in a medical or educational activity.
