Background  Schistosomiasis and STH are among the list of neglected tropical diseases considered for control by the WHO. Although both diseases are endemic in Zimbabwe, no nationwide control interventions have been implemented. For this reason in 2009 the Zimbabwe Ministry of Health and Child Care included the two diseases in the 2009–2013 National Health Strategy highlighting the importance of understanding the distribution and burden of the diseases as a prerequisite for elimination interventions. It is against this background that a national survey was conducted.    Methodology  A countrywide cross-sectional survey was carried out in 280 primary schools in 68 districts between September 2010 and August 2011.  Schistosoma haematobium  was diagnosed using the urine filtration technique.  Schistosoma mansoni  and STH (hookworms,  Trichuris trichiura, Ascaris lumbricoides ) were diagnosed using both the Kato Katz and formol ether concentration techniques.    Main findings  Schistosomiasis was more prevalent country-wide (22.7%) than STH (5.5%). The prevalence of  S. haematobium  was 18.0% while that of  S. mansoni  was 7.2%. Hookworms were the most common STH with a prevalence of 3.2% followed by  A. lumbricoides  and  T. trichiura  with prevalence of 2.5% and 0.1%, respectively. The prevalence of heavy infection intensity as defined by WHO for any schistosome species was 5.8% (range 0%–18.3% in districts). Only light to moderate infection intensities were observed for STH species. The distribution of schistosomiasis and STH varied significantly between provinces, districts and schools (p<0.001). Overall, the prevalence of co-infection with schistosomiasis and STH was 1.5%. The actual co-endemicity of schistosomiasis and STH was observed in 43 (63.2%) of the 68 districts screened.    Conclusion and recommendations  This study provided comprehensive baseline data on the distribution of schistosomiasis and STH that formed the basis for initiating a national control and elimination programme for these two neglected tropical diseases in Zimbabwe.
