12 - Mapping WASH-related disease risk: A review of risk concepts and methods

The report notes a lack of consensus on the definition of disease risk in the literature, which limits the interpretability of the resulting analyses and could affect the quality of the design and direction of public health interventions. [...] To interpret the existing measures, we propose that risk should be understood as a Frequencies function of the probability and severity of impact of a risk event, as done in the field of public health Common categories of frequencies used as (Kirch, 2008; WHO, 2012). [...] For example, cumulative incidence can the frequency of days where R0>1 as a measure be interpreted as a measure of the probability of of the at-risk period during which outbreaks or contracting a disease or as a measure of the severity epidemics can occur or persist (Y. [...] In the case of outbreak-prone Measures of duration used for risk mapping have diseases, the use of cumulative incidence over a included the length of a disease's transmission fixed period can conceal the frequency (measure of season and the duration of outbreaks and epidemic probability) and incidence (measure of severity) of waves. [...] 1 In contrast, risk frameworks: One example of this type of infectious disease • have focused on evaluating the propensity risk framework is the Water Associated Disease of a community to be adversely affected by Index (WADI) (Dickin et al., 2013), which was used disease, extending the analysis of risk beyond to assess the risk of dengue, schistosomiasis and incidence and mortality.
