In other words, the population that will need to be successfully vaccinated to reduce the population at risk below the epidemic threshold. It can be similarly shown that even if this target is not reached, then the epidemic will be put off until a future date when the susceptible unvaccinated children will have grown older and therefore be able to cope with the infection better. This is illustrated in Fig. 2. 5 Investigating food- and water-borne epidemics Other epidemiological techniques are useful for investigating food- and water-borne epidemics, particularly case–control and cohort study methods.
Three factors describe a point source epidemic: . the epidemic curve; . the incubation period of the disease; . the time of infection. If only two of these factors are known, then the third can be deduced. From the epidemic curve, the median (or geometric mean) of the incubation periods is determined. If the disease is known from its clinical features, then the incubation period will also be known (Chapter 19). Therefore, by measuring this known incubation period back in time from the median incubation period on the curve or the minimum incubation period from the beginning of the curve, the time of infection can be calculated.
Conveniently marked on a map. 3. Time: annual, monthly (seasonal), daily and hourly (nocturnal/diurnal). The number of cases occurring within each time-period is plotted on a graph. These aspects will be covered in greater detail later. In a point source epidemic, the number of cases of the disease occurring each day are plotted on a graph to produce an epidemic curve. The earliest cases will be those with the minimum incubation period and the last of the cases are those with the maximum incubation period if all were infected at a single point in time, as illustrated in Fig.
