Healthcare-associated infections (HAIs) are infections that patients acquire during the course of receiving healthcare treatment for other conditions. These infections related to medical care can be devastating and even deadly. As the nation’s health protection agency, CDC is committed to helping all Americans receive the best and safest care when they receive healthcare services.
CDC strives to understand how HAIs happen and to develop appropriate interventions. HAIs are an important public health problem. Approximately 1 out of every 20 hospitalized patients will contract an HAI.
The following documents provide information about the problem of HAIs in the United States.
