Preventing the Spread of Infection in the Hospital

Certain infections can spread from person to person. This is why your loved one may be put in a special room while in the hospital. Restrictions may be placed on who can go in and out of that room and what protection must be worn. Read this sheet to better understand why this is done.

How infection spreads

Infection is caused by germs. An infected person carries germs that he or she can give to others. Even a person who doesn’t feel sick can still carry and spread germs. Germs can cause infection by traveling through the air or through direct contact. Or when people touch the same surface in a room. This includes a doorknob, sink faucet, table, or chair. 

How you can get infected

To infect you, germs first have to get inside your body. You can get infected by touching a contaminated person or object. You can also get infected by breathing contaminated air. This is why good hand hygiene and other infection control advice, such as wearing a mask, are so important. Hand hygiene means handwashing with soap and water. Or using alcohol-based gels or foams that don't need water.

Preventing infection

To stop infection from spreading, healthcare workers may do one or more of the following:

  • Put an infected person in a private room. Or putting him or her in a room with others who have the same infection. (This depends on what kind of infection the person has.)

  • Wear a mask, gloves, gown, or other items.

  • Wear an air filter (respirator) for some infections.

  • Wash hands with soap and water or use an alcohol-based hand sanitizer before going into or leaving a person's room.

What you can do

Here’s how to help stop the spread of infection:

  • You may be asked to wear a mask, gloves, gown, or respirator when you visit. Follow any directions carefully. Clean your hands with soap and water or use an alcohol-based sanitizer before touching the person.

  • Practice good hand hygiene. This is especially important after using the bathroom. And before and after touching the person or the person's surroundings.

  • Keep your hands away from your face.

  • Cough or sneeze only into a tissue. Wash your hands with soap and water for 15 to 30 seconds after you cough or sneeze.

  • Don't use the person’s bathroom.

  • Don't visit someone in the hospital if you feel sick. Don't visit if you have been exposed to an illness such as the flu, chickenpox, or measles.
