Infections can be transmitted through various routes, including direct contact, airborne transmission, vector-borne transmission, and fomite transmission. Direct contact transmission occurs when there is physical contact between an infected individual and a susceptible person. Airborne transmission involves the spread of infectious agents via respiratory droplets. Vector-borne transmission occurs when an insect or animal carries the infectious agent from one host to another. Fomite transmission involves the spread of infectious agents through contaminated objects.
