What Hospital-Acquired Infections Are

A hospital-acquired infection (HAI) is any illness you catch while receiving care for a different condition. These infections develop at least 48 hours after your admission to the facility. They are not related to the reason you originally arrived for treatment.

Hospitals are high-traffic areas where many people are vulnerable to illness. Germs spread through direct contact with medical staff, shared equipment, or surfaces like bed rails and doorknobs. Even with strict sanitization protocols, it is difficult to keep a hospital environment completely sterile.

Medical devices like catheters and ventilators are necessary for treatment, but they can act as pathways for bacteria. These tools bypass your body’s natural defenses, such as your skin or immune system. Once a device is inside your body, germs can travel along the surface to cause a serious infection.

Healthcare workers follow strict hygiene rules to minimize your risk. This includes regular hand hygiene using soap or alcohol-based sanitizer and wearing personal protective equipment. We also limit the use of invasive devices to only when they are absolutely required for your recovery.

You have an active role in preventing infections during your stay. Do not hesitate to remind your doctors and nurses to clean their hands before touching you. Keep your surgical site or insertion points for IVs clean and dry, and report any signs of redness or fever to your care team immediately.
