Chain of Infection - ANSWER-1)Infectious agent= organism with ability to cause disease; greater virulence, invasiveness, and pathogenicity => increased odds of infection 2) Reservoir: place where microbes can persist and reproduce 3) Portal of Exit: way for microbe to leave the reservoir 4) Mode of transmission: method of microbe transfer from one place to another 5) Portal of entry: opening that allows microbe to enter host 6) Susceptible host: Lacks immunity or physical resistance to p...
