A surgical mask is a disposable face covering worn by healthcare professionals during medical procedures to protect against harmful particles in the air and germs released when breathing, talking, coughing, or sneezing. It typically has multiple layers, including a filtration layer that traps particles to filter out bacteria and viruses. Surgical masks are designed to fit over the nose and mouth and are secured with ear loops or ties. They are crucial in preventing the spread of infections from healthcare workers to patients and vice versa. Proper disposal after use and following hygiene protocols are essential to maintain their effectiveness.
