Take any medicine prescribed by a doctor. It is made to help you!
Don't be active. It's usually a good thing, but it's not if you're sick.
Don't go near anyone or anything. Exposing yourself to new germs is not a good idea, and you don't want to spread your germs to other people.
Wash your hands. Use soap and warm running water. Hand sanitizer is not a replacement for washing your hands, but can be helpful when you do not have access to running water. Staying clean is very important to keep germs away. Try to take showers frequently. Avoid taking baths as much as possible, as you end up sitting in whatever you were trying to wash off.

Not only is it important to keep your hands clean, but you should also keep your mouth clean; brush your teeth more than usual.
Don't put your fingers in your mouth, eyes, ears, nose; any place thatcould allow germs to get inside your body. If you have any open cuts or sores, keeping them clean and covered is essential because these act as "portals" to allow germs into your body.
exposing yourself to germs will give your immune system a better idea of what they are fighting, thus making your immune system stronger
