Epidemiological mapping of schistosomiasis and soil transmitted helminthiasis in 19 states and the federal capital territory (fct), Nigeria

Meeting Abstract #1785
The coordinated mapping of Schistosomiasis and Soil Transmitted Helminthiasis (STHs) was conducted in 19 States and the FCT of Nigeria from November 2013 to May 2015. Both diseases were mapped using a novel technique; the LINKS system developed by the Task Force for Global Health (TFGH), on Android devices and cloud based data reporting and management. The application of these devices supported the transition from paper-based questionnaires to electronic data collection tools. A total of 108,472 children from 2160 schools in 433 LGAs in 19 States and the Federal Capital Territory (FCT) were examined for Schistosomiasis and STHs. The Kato-Katz, filtration techniques were used to examine stool and urine samples Also, Water, Sanitation and Hygiene (WASH) information for schools and school children were collected. The result of this survey revealed that all the States and the FCT were endemic for one or both diseases with an overall prevalence of 9. 5% for Schistosomiasis and 27% for STHs. However, the data captured by LGA; the intervention unit, showed that prevalence of infections varied from low to high risk. The prevalence of infections was significantly higher in males than in females for both diseases. STHs were more prevalent among the younger age group (5-10years) while Abster #1785Schistosomiasis was more prevalent among the older age group (11-16 years). Heavy intensity levels were nearly equal for S. haematobium (24. 31%) and S. mansoni (23. 48%). The intensity levels of S. haematobium and A. lumbricoides showed statistical significant difference (P<0. 05) with respect to sex in this survey. STHs and Schistosomiasis were seen among pupils who claimed to defeacate in the school toilets, around the school compound and outside school environment. Of the 433 LGAs surveyed the number of LGAs requiring interventions for Schistosomiasis and STHs were 359 and 237 respectively. The mapping exercise provided insight into disease distribution and intensity in 19 States and the FCT. It is recommended that Government and stakeholders should scale up mass deworming alongside WASH interventions.
