摘      要：Background:The current mainstay for control/elimination of onchocerciasis and soil-transmitted helminthiasis(STH)relies on ivermectin-and mebendazole/albendazole-based preventive ***,children under fve years of age have been excluded in both research activities and control programs,because they were believed to have insignifcant infection *** is therefore a need for up-to-date knowledge on the prevalence and inten‑sity of STH and onchocerciasis infections in this age *** study aimed at assessing the rates and intensities of onchocerciasis and STH infections in children under fve years of age who are excluded from ivermectin-or mebenda‑zole/albendazole-based preventive ***:A series of cross-sectional surveys was conducted in four Health Districts in the Centre and Littoral Regions of Cameroon between 2018 and *** subjects aged 2 to 4 years,were screened for prevalence(or infection rate)and intensity[number of eggs per gram of stool(epg)or number of microflariae per skin snip(mf/ss)]of STH and onchocerciasis infections respectively using the Kato-Katz and skin snip ***-square and the nonparametric tests(Mann Whitney and Kruskal Wallis)were used to compare infection rates and intensities of infections between Health Districts and genders,***:A total of 421 children were enrolled in this *** overall prevalence of onchocerciasis was 6.6%[95% confdence interval(CI):4.3‒9.9],ranging from 3.6%(in the Ntui Health District)to 12.2%(in the Bafa Health District).The intensity of infection ranged from 0.5 to 46 microflariae per skin snip[median:5;interquartile range(IQR):2.25‒8.5].The overall prevalence of STH was 9.6%(95%CI:6.5‒13.9),with a high infection rate(29.6%)in the Akonolinga Health *** STH species(Ascaris lumbricoides and Trichuris trichiura)were found among infected *** median intensities of STH infections were 1,992 epg(IQR:210‒28,704)and 96 epg(IQR:48‒
