Mapping of Schistosomiasis and Soil-Transmitted Helminthiasis in the Regions of Centre, East and West Cameroon

Schistosomiasis and soil-transmitted helminthiasis (STH) are a major public health problem in Cameroon. The national control strategy of these diseases was based on historical data collected 25 years ago, which might be outdated in some situations due to several factors including control activities, improved or degraded sanitation and hygiene, socio-economic improvement and disease transmission dynamics. To help planning, improving control strategies and evaluation of control activities, there was a need to update the distribution of schistosomiasis and STH. We conducted parasitological surveys in three regions of Cameroon, i.e. Centre, East and West. Our results showed a significant decrease of STH infection prevalence and intensities in all these three regions, in comparison to previous mapping data, with an overall decline of prevalence from 81.1–93% to 10.5–46.6%. These results show the positive impact of annual deworming campaigns, and illustrate the progressive success of the national programme for the control of schistosomiasis and STH in Cameroon. Furthermore, our results showed an increase of the number of high transmission foci of schistosomiasis, and allowed identifying new health districts requiring mass treatment with praziquantel, and those where deworming should be reinforced

Au sujet de l'utilisation de relations empiriques hnu(CT/Max)=f(ID) en vue de l'interprétation des potentiels d'ionisation.

The UV absorption spectra of the charge transfer (CT) complexes formed by iodine with C2H2NH, C2H2O and C2H2S were studied in order to interprete the first ionization potential of these organic molecules by using the empirical relationships hn(CT/Max)=f(ID). Taking into account the basical specificity of these relations, the trend of the CT data shows C2H2NH and C2H2O to be n-donors towards iodine and the first ionization potential of the same donors could be ascribed to the removal of an electron from a non-bonding orbital localized on the heteroatom. Theoretical calculations however do not support this interpretation in the case of C2H2NH
