HIV stands for “human immunodeficiency virus.” It’s a virus that can only infect humans and leads to the weakening of the immune system. The immune system is the body’s system for fighting disease. When it’s compromised or weakened, a person becomes vulnerable to all kinds of bacteria, viruses, or other agents that cause disease.
HIV is the virus that causes AIDS. It damages your immune system, making it easier for you to get sick. HIV is spread during sex, but condoms can help protect you.
