The outcome of exposure to an infectious agent depends, in part, upon multiple host factors that determine individual susceptibility to infection and disease. The goal of secondary prevention is to halt the progress of an infection during its early, often asymptomatic stages so as to prevent disease development or limit its severity; steps important for not only improving the prognosis of individual cases but also preventing infectious agent transmission. Broadly, public health efforts to control infectious diseases focus on primary and secondary prevention activities that reduce the potential for exposure to an infectious agent and increase host resistance to infection. A susceptible host is an individual who is at risk of infection and disease following exposure to an infectious agent. ./cache/cord-355024-v5lahyw4.txt ./txt/cord-355024-v5lahyw4.txt
