Surgical face masks are crucial in preventing and controlling infectious diseases. They are designed to filter out large airborne particles, including bacteria and viruses, from the wearer's nose and mouth, reducing exposure to potentially infectious droplets. These masks are essential in healthcare settings, particularly in hospitals and medical facilities where exposure to infectious diseases is high. During outbreaks like the COVID-19 pandemic, the use of surgical masks extends beyond healthcare settings to the general public, reducing transmission rates. They capture respiratory droplets expelled by the wearer, protecting others in the vicinity.

Surgical masks also promote good respiratory hygiene by preventing individuals from touching their faces, which is a common way for viruses and bacteria to enter the body. They also help contain respiratory secretions, reducing the risk of contaminating surfaces and objects. Surgical masks are typically made from multiple layers of non-woven fabric, with an outer layer being water-resistant and the inner layer absorbing moisture. They are disposable and designed for single use to maintain hygiene and effectiveness.
