Surgical Masks

Surgical masks have always played an important role in preventive medicine. With the advent of Swine and Bird flu, surgical masks have gained even more significance in the world of medicine. Surgical masks were once only worn in hospitals by health care professional and patients. Surgical masks help protect health care workers from bodily fluids, blood, various lung secretions and reduce spread of microorganisms from patients to health care worker and vice versa.

Since the advent of influenza virus, two other airborne viruses have been discovered that have the potential to cause many deaths. Large-scale pandemics of bird and swine flu viral infections have led to use of surgical masks outside health care facilities. The availability of relatively cheap surgical masks has led to high usage among populations in South East Asia. In many Oriental countries, use of surgical masks is a frequent public site to help avoid spread of the common cold virus.

Since the Bird flu scare several years ago, surgical masks have become popular among the public in many parts of America, including Canada and Mexico. There is abundant clinical evidence indicating that surgical masks play an important role in protecting health care workers from contaminated body fluids and aerosol particles. Surgical masks are primarily worn in hospital to prevent inhalation of aerosolized particles including microorganisms.

Awareness of serious viral and bacterial infections has led to development of guidelines regarding use of surgical masks in many health care facilities. Today, surgical masks are advocated for health care professional by the following institutions:

- American National Standards Institute Practice for
Occupational and Educational Eye and Face Protection
- Association of Perioperative Registered Nurses
- Joint Council on Accreditation of Healthcare Organizations
- National Committee for Quality Assurance
- National Institute for Occupational Safety and Health
- Occupational Safety and Health Administration
- The Food and Drug Administration
