Chain of Infection As described above‚ the traditional epidemiologic triad model holds that infectious diseases result from the interaction of agent‚ host‚ and environment. 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

developing a computer model of the spread of an infectious disease‚ the student develops an understanding of the role of the infection rate and the removal rate on the spread of the disease. The Threshold Theorem of Epidemiology claims that the extent of spread of an epidemic can be predicted if three values are known: initial number of susceptible people (S(0))‚ the infection rate (K)‚ and the removal rate (by quarantine or cure) (Q). The extent of the spread of the epidemic is indicated by the percentage

of the HPV lifecycle is mainly derived from research on the high-risk group of HPV viruses‚ in particular HPV 16. However‚ with slight modifications‚ life cycle models of HPV 16 can be applied to other HPV groups as well.17 The principal route of transmission for HPV is skin to skin contact. Epidemiologic evidence shows that sexual behavior greatly influences the incidence and prevalence of HPV infections.18 To develop infection‚ infectious particles must find their way to cells in the basal layer
