Standard precautions and post exposure prophylaxis for preventing infections.
In health care set up, risk of acquiring infection by both patients and health care worker (HCW) from each other is fairly high. Despite progress, hospital acquired infections (HAI) are a problem in both developed and developing countries and are an important cause of death. Many different microbes cause HAI in both patients and HCW; these include various commensals, pathogenic bacteria, viruses, parasites, and fungi. Among these HIV, hepatitis B, and hepatitis C are of major significance to HCW. 'Standard precautions' have now replaced the term 'universal precautions', and are designed to reduce the risk of transmission of microorganisms in health care set-up from both recognized and unrecognized sources. Ultimate aim is to reduce the risk of disease transmission in the healthcare setting, both to the patient and the provider, and thus reduce morbidity. This applies to all patients, regardless of their diagnosis and expands the coverage of universal precautions by recognizing that any body fluid may contain contagious and harmful microorganisms. This article reviews the standard precautions and discusses current guidelines on post exposure prophylaxis (PEP).
