Using disposable gloves: 

Disposable gloves are gloves that you use one time and then throw away. They can protect your health and the health of the person you're caring for. They help keep germs and infection from spreading to you and to the other person.

Use gloves whenever you might touch body fluids, such as saliva, blood, urine, or stool. Use a new pair of gloves when you touch areas near a cut (incision) made by a doctor. And some people use gloves when bathing someone. Gloves can also be used when you put medicines on the skin and when you give shots.

Gloves do not protect you from poking your skin with sharp objects. So if you are handling sharp objects, such as needles, be sure that the object doesn't poke a hole in the glove. Handle these types of objects carefully.

Gloves can help prevent infection from body fluids. But if there are times when you choose not to use gloves or don't have any, keep your hands as clean as possible. After coming into contact with body fluids, wash your hands as soon as you can. And keep hand sanitizer available.
