Healthcare-Associated Infection (HAI)

A healthcare-associated infection (HAI) is an infection a patient acquires while receiving treatment in a healthcare facility, often spread through contaminated surfaces, equipment, or hands that environmental cleaning aims to prevent.

In Depth

Common HAIs include surgical-site infections and C. difficile, many linked to surfaces in the patient environment. Rigorous cleaning and disinfection of high-touch surfaces measurably reduce HAI transmission.

Why It Matters

HAIs harm patients and carry major financial and reputational costs for providers. Environmental cleaning is one of the most cost-effective levers for reducing them.
