Upon publication of the original article [1], it was noticed that the second sentence of Section Methods, sub-section study setting, ‘Three slum kebeles in Gullele Sub-City’s District (Woreda) 01 and four slum kebeles in Lideta Sub-City’s District 05 were included in the study’ was incorrectly given as ‘Four slum kebeles in Gullele Sub-City’s District (Woreda) 01 and three slum kebeles in Lideta Sub-City’s District 05 were included in the study’. This has now been acknowledged and corrected in this erratum.
