TL;DR: Of the various flourosis prevention methods tried in Ethiopia, the treatment of surface water has been shown to be the most feasible and effective for towns and large commercial farms in the Rift Valley, although defluoridation methods should be considered for smaller rural communities.

TL;DR: This paper tries to make sense of this variability in the variety of ways the COVID-19 epidemic is unfolding across the globe by exploring the important role that context plays in these different CO VID-19 epidemics; by comparing COVID's epidemics with other respiratory diseases, including other coronaviruses that circulate continuously; and by highlighting the critical unknowns and uncertainties that remain.

TL;DR: In this paper, the relative performance of diatoms and macroinvertebrates to measure municipal and industrial impacts on the ecological integrity of the three major rivers flowing through Addis Ababa was assessed.

TL;DR: It is indicated that children living in close proximity to a man-made reservoir in Ethiopia are at higher risk of malaria compared to those living farther away, and it is recommended that sound prevention and control programme be designed and implemented around the reservoir to reduce the prevalence of malaria.

TL;DR: Analysis of hydrochemical, economic and demographic factors in the spatial distribution of high‐fluoride domestic water sources indicates that the fluorosis problem has become more serious in the Rift Valley in recent decades.
