1. Mention one disease caused by a virus. 2. What is a vaccine? 3. What is the long name for AIDS? 4. What is the name of the disease transmitted by mosquitoes?

One disease caused by a virus is HIV, which leads to AIDS. HIV, or Human Immunodeficiency Virus, attacks the immune system, making it difficult for the body to fight off infections and diseases. Without treatment, it can progress to AIDS, severely compromising the body's defenses. A vaccine is like a superhero for your immune system! It trains your body to recognize and combat specific viruses or bacteria by introducing a harmless piece or a weakened form of the pathogen, so when the real threat arrives, your body is ready to battle. Vaccines have been instrumental in controlling diseases, keeping us healthy, and even eradicating some, like smallpox!
