Limited understanding of disease in low resource communities continues to hamper improvements in health. We evaluated household pit latrine sampling as a non-invasive approach to investigate important fecal pathogens such as Giardia lamblia and Cryptosporidium spp. in impoverished communities where health-seeking behavior limits the sensitivity of health facility-based surveillance. Fecal samples were collected from pit latrines in randomly selected households and from patients presenting to the only hospital in the region during the same time periods. Samples were tested with a commercially available ELISA. Giardia household prevalence was 28.7% in 2016 and 48.4% in 2017, while individual samples from hospital submission had a Giardia prevalence of 2.4% in 2016 and 8.0% in 2017. Cryptosporidium was only found in one household. Results suggest that pit latrine surveillance for fecal-borne infections provide course estimates of community infection levels that are unbiased by health seeking behaviors and allow surveillance of vulnerable sectors of a population.

Pit latrines-the simplest on-site sanitation system-have been extensively used in developing countries in Asia for a long time. However, pit latrines are pollution and health risk hotspots that can cause widespread contamination. It is preferable to upgrade them to septic tanks, which are more advanced, effective, and simple alternatives.

Background: Routine epidemiological data are essential for monitoring the effectiveness of preventive chemotherapy (PC), optimizing resource allocation, and addressing the evolving needs in the elimination of soil-transmitted helminthiasis (STH). This study assesses the prevalence, intensity, and associated risk factors of STH following five rounds of albendazole-based PC in three implementation units (IUs) in Ondo State, Nigeria.
Methodology: Fresh stool samples were collected from 2,093 children aged 5-14 years across 45 systematically selected schools in three IUs: Ese-Odo, Irele, and Ile-Oluji.

Background: Soil-transmitted helminth (STH) infections are a significant public health concern in developing countries, particularly affecting children (5-9 years) and adolescents (10-12 years). This study investigated the prevalence of STH infections, examined associated risk factors, and assessed their impact on the nutritional status of children and adolescents.
Methods: An analytical cross-sectional study was conducted within schools and took place from April to June 2023 and involved 382 participants in Calabar, Nigeria.

Background: Wastewater-based epidemiology (WBE) is already being adopted for the surveillance of health conditions of communities and shows great potential for the monitoring of infectious pathogens of public health importance. There is however paucity of robust data to support extensive WBE in Nigeria. This study evaluated the prevalence of clinically relevant infectious pathogens and provided antimicrobial resistance profiles of bacteria pathogens in wastewater canals in Lagos State at a single point in time.

Many technical aspects are associated with helminth egg isolation and enumeration that affect how efficiently eggs are recovered from samples. This study investigated Ascaris egg recoverability when samples were washed with or without pressure, and from different sample types (water, effluent, ventilated improved pit latrine [VIP], urine diversion dry toilet [UDDT], dried, fatty, and septic tank sludges, and soil) when processed with water, ammonium bicarbonate, and 7X®. We also looked at egg recovery after flotation with zinc sulfate, magnesium sulfate, and sodium nitrate at specific gravities of 1.
