What Are Infections?
If germs get inside your body, they can multiply and cause an infection. Your body's immune system fights off the germs with special cells. It can become a full-on fight against the nasty invaders — and you won't feel better until your body wins! If your body has a little trouble fighting the infection by itself, your doctor may prescribe medicine like antibiotics to help. So get some rest and let your body do the work!
