What are the principle routes of transmission of nosocomial infections?
Nosocomial infections, that develop as a result of a stay in hospital or are produced by micro-organisms and viruses acquired during hospitalisation may have several different transmission routes: contact, droplet, air, water, food, or disease vector carrying and transmitting an infectious pathogen, or blood .
