he transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.

Direct Contact Transmission

Direct contact transmission occurs through direct body contact with the tissues or fluids of an infected individual. Physical transfer and entry of microorganisms occurs through mucous membranes (e.g., eyes, mouth), open wounds, or abraded skin. Direct inoculation can occur from bites or scratches. Examples include organisms such as rabies, Microsporum, Leptospira spp., and staphylococci, including multidrug-resistant (MDR) species methicillin-resistant Staphylococcus aureus and Staphylococcus pseudintermedius (MRSP). This is probably the most common and highest-risk route of pathogen transmission to patients and personnel.
