More specifically, transmission occurs when the agent leaves its reservoir or host through a portal of exit, is conveyed by some mode of transmission, and enters through an appropriate portal of entry to infect a susceptible host. This sequence is sometimes called the chain of infection. Figure 1.19 Chain of Infection. Image Description.
Direct contact transmission. Occurs through direct contact with the tissues or fluids of an infected individual. Microorganisms enter through mucous membranes (e.g., eyes, mouth), open wounds, or abraded skin. Direct inoculation can occur from bites or scratches. The most common and highest risk route of pathogen transmission.
