Things You Can Do to Help Prevent the Spread of Germs

When you cough or sneeze, you send tiny germ-filled droplets into the air. Colds and flu usually spread this way. Here are things you can do to help prevent the spread of germs:

Cover your mouth and nose when you sneeze or cough. Sneeze or cough into your elbow, not your hands.
Cleaning your hands often - always before you eat or prepare food, and after you use the bathroom or change a diaper.
Avoiding touching your eyes, nose or mouth.
Hand washing is one of the most effective ways to stop disease. Soap and water work well to kill germs. Wash for at least 20 seconds and rub your hands briskly. Disposable hand wipes or gel sanitizers also work well.

Kidney Stones

A kidney stone is a solid piece of material that forms in the kidney from substances in the urine. Most pass out of the body without help from a doctor. If a stone does not pass on its own and gets stuck in the urinary tract, you may need treatment. Learn the signs of kidney stones and how they are treated.

Nutrition for Older Adults

Pneumonia is an infection in one or both of the lungs. Many germs, such as bacteria, viruses, and fungi, can cause pneumonia. You can also get pneumonia by inhaling a liquid or chemical.
