    Wastewater irrigation is associated with several benefits but can also lead to significant health risks. The health risk for contracting infections from Soil Transmitted Helminths (STHs) among farmers has mainly been assessed indirectly through measured quantities in the wastewater or on the crops alone and only on a limited scale through epidemiological assessments. In this study we broadened the concept of infection risks in the exposure assessments by measurements of the concentration of STHs both in wastewater used for irrigation and the soil, as well as the actual load of STHs ova in the stool of farmers and their family members (165 and 127 in the wet and dry seasons respectively) and a control group of non-farmers (100 and 52 in the wet and dry seasons, respectively). Odds ratios were cal culated for exposure and non-exposure to wastewater irrigation. The results obtained indi cate positive correlation between STH concentrations in irrigation water/soil and STHs ova as measured in the stool of the exposed farmer population. The correlations are based on reinfection during a 3 months period after prior confirmed deworming. Farmers and family members exposed to irrigation water were three times more likely as compared to the con trol group of non-farmers to be infected with Ascaris (OR = 3.9, 95% CI, 1.15–13.86) and hookworm (OR = 3.07, 95% CI, 0.87–10.82). This study therefore contributes to the evi dence-based conclusion that wastewater irrigation contributes to a higher incidence of STHs infection for farmers exposed annually, with higher odds of infection in the wet season.

    Implication of Urban and Peri-Urban Agricultural Wastewater Irrigation to Malaria Transmission in Kumasi
    (2018) Abubakari Amina; Asiedu Larbi John; Abaidoo R. C
    Malaria transmission within areas of wastewater irrigation activities was the focus of this study where seven thousand and seventeen (7017) progressive data from health facilities within seventy-seven (77) communities were assessed. Results indicated approximately 3698 and 3319 cases of malaria, respectively for areas of wastewater irrigation activities and areas devoid of wastewater irrigation activities. Statistical result at 95% confidence interval (CI) gave a P-value of 0.1914 between these two multi-urban and peri-uran settings. The mean ± SEM of A (irrigation activity zones) was 13 ± 3.816 (N=4) and mean ± SEM of B (non-irrigation activity zones) was 8.167 ± 1.515 (N=6). The resulting difference between the means A and B was 5.083 ± 3.562. Again, identification and quantification of Anopheles spp density using Gillies and de-Meillon protocol showed quite a high number of Anopheles spp densities in farrows followed by ponds and streams presenting the least Anopheles spp density. This should therefore bring to the attention of many that though urbanization indicates to some extent development, nevertheless could sometimes contribute to malarial transmission due to certain anthropogenic activities.
