large crowd gathered outside under a tent-like structure decorated with red and green fabric. Inside, a smaller group of people is seated on plastic chairs, facing the crowd. One person in the foreground wears a blue shirt, and another a white shirt with the words "Getting to zero new HIV infection". The outdoor crowd appears to be dense, with many wearing white or light-colored clothing. A sign is visible within the crowd, although the text is not clear. The environment suggests a public gathering, possibly a rally or community event.
