Описание:
Measles like smallpox is a virus that causes rashes on the body. Also known as Hasbah or rubeola, it's actual origin is unknown (whether it came from dogs to us or cattle or wherever) but it is seen as a crowd disease, spreading faster in densely populated places. It was discovered by Francis Home to be an infectious agent.Добавлено на ленту времени:
