Healthcare-Associated Infections (HAI)

A healthcare-associated infection (HAI) is an infection that a person can acquire while receiving treatment in a healthcare facility for another condition. There are various types of HAIs, which are often named after the site of the body in which they occur. Common types of infections are catheter-associated urinary tract infections (CAUTIs), central line-associated bloodstream infections (CLABSIs), surgical site infections (SSIs), and ventilator-associated events (VAEs). Some types of bacteria that are known to cause HAIs are methicillin-resistant Staphylococcus aureus (MRSA), Clostridioides difficile (CDI), Acinetobacter, Pseudomonas, Carbapenem-resistant Enterobacterales (CRE), and Vancomycin-resistant Enterococci (VRE).
