Spatial Modelling of Soil-Transmitted Helminth Infections in Kenya: A Disease Control Planning Tool (original) (raw)
Figure 4
Continuous predicted combined soil-transmitted helminth (STH) prevalence and probability contour maps for Kenya.
Probability contour map shows the probability that combined STH prevalence exceeds 20%. Estimates of predicted prevalence are the mean posterior predictive values from a Bayesian space-time model for (a) 2009 and (b) 1989. The probability contour maps show the spatial distribution of probability that combined STH prevalence is >20% for (c) 2009 and (d) 1989. Biological transmission limits were estimated using maximum land surface temperature (LST), assuming no transmission when maximum LST exceeds 40{degree}C.
