Soil-transmitted helminthic (STH) infection is a significant public health concern in India and a leading cause of morbidity, particularly in resource-constrained regions. Human transmission occurs through eggs or larvae in faeces, which contaminate soil in areas with poor sanitation. Infection results in intestinal blood loss leading to iron deficiency anaemia and protein malnutrition, impaired physical and cognitive development, abdominal pain and diarrhoea.
Aims & Objectives: To study the six-year prevalence trend of STH infections in middle  and upper Assam region from the records of patients attending JMCH.
Materials & Methods: This retrospective cross-sectional study was done by collecting data from records of STH isolates from January 2017 to November 2022. Data were analyzed using EpiInfo and chi square test to analyze the association between different variables using p value < 0.05 as statistically significant.
Results: From a total of 1352 stool samples received over 6 years, 200 (14.8%) were positive for intestinal parasites among which STH were 102 (51%). Six different parasites were reported with Ancylostoma duodenalae       being the predominant (59.8%) followed by Trichuris trichura (22.5%) and Ascaris lumbricoides (19.6%). Further, 2% recorded co-infection with 3 parasites and 6.5% with 2 parasites. The prevalence was higher in males (86%) than females (14%) (p=1.27) and 40-60 years age group showed highest prevalence.
Conclusion: Intestinal infection due to Hookworm was the most common STH identified in this study. Improvement in sanitation, periodical deworming and health education schemes are indispensable for the prevention and control of STH

Background: Intestinal parasitic infections are a major public health problem in developing countries like India. The prevalence and distribution of parasites vary from region to region within a country. Stool routine examination is a great tool in identifying various parasitic and nonparasitic causes in patients presenting with diarrhea to a health facility. Knowledge of the prevalence and distribution of different parasites causing infection in a particular region helps to devise appropriate prevention and control measures.
Aim and Objectives: The aim of this study was to analyzediarrheic stools submitted to the parasitology lab by stool routine examination& to identify the prevalence and distribution of intestinal parasites causing infection in this particular region.
Material & Methods: A total of 545 stool samples received in the parasitology lab for stool routine examination were evaluated for gross and microscopic findings with an emphasis on the detection of intestinal parasites. Stool samples were evaluated with normal saline and iodine mounts.
Results: A total of 545 stool samples were examined out of which 40 were found to have intestinal parasitic infection with a prevalence rate of 7.6%. Parasitosis was seen more in males (8.2%) as compared to females (6.4%). Parasitosis was found to be mostly prevalent in the age group 11- 20 years followed by 31-40 years (9.5%). Cyst of Giardia lamblia (35%) was the most commonly detected protozoa followed by cyst & trophozoite of Entamoeba histolytica (22.5%).
Conclusion: Intestinal protozoal infections are more prevalent than helminthic infections. Improvement in drinking water quality and personal and food hygiene will help in reducing parasitic infections.
