A society for social medicine is a group of people who work together to make sure everyone stays healthy and happy. They do things like studying how diseases spread from one person to another, and figuring out the best ways to prevent those diseases. They also try to make sure that people who are sick get the care and treatment that they need, no matter how much money they have or where they come from.
Think of it like a big team of doctors, scientists, and other experts who want to make the world a better, healthier place for everyone. They want to make sure that everyone has access to clean water, healthy food, and safe living conditions. And they also want to make sure that everyone has a chance to be healthy and happy, no matter who they are or where they come from.
