A silent threat lurks in the soil and water, sapping the vitality of a generation.
Learn MoreImagine a child, eager to learn and grow, but held back by an unseen enemy. For many school-aged children in rural Nigeria, this is not a hypothetical scenario but a daily reality. Intestinal parasitic infections represent a significant public health burden in less developed countries, causing high morbidity and mortality, particularly among the young.
These infections are more than just a stomach ache; they are linked to malnutrition, anemia, and learning disabilities, creating a cycle of illness that hampers both physical and cognitive development. This article explores the prevalence of these parasites in the rural communities of Anambra State, Nigeria, and the ongoing fight to protect its children.
Most Vulnerable
Highest risk group for intestinal parasitic infections
Infection Rate
Nearly 1 in 4 children infected in studied communities
Most Common
Accounts for over 50% of all parasitic infections
Their daily behaviors—playing in soil, eating with unwashed hands, and unhygienic toilet practices—make them particularly susceptible to infection 5 .
Many households rely on well water (72.8% of infected children), which is often contaminated with parasite eggs and cysts 7 .
Walking barefoot exposes children to soil-transmitted helminths that can penetrate the skin, particularly in areas with poor sanitation.
The consequences extend far beyond a temporary illness. Studies have consistently shown that intestinal parasites are a major contributor to undernutrition in children. Parasites like hookworm and Ascaris lumbricoides (roundworm) compete for nutrients, cause internal bleeding, or lead to malabsorption of essential vitamins and minerals 1 5 . This can result in:
Low height-for-age due to chronic malnutrition
Low weight-for-height indicating acute malnutrition
Low weight-for-age reflecting overall malnutrition
This link between infection and malnutrition underscores why controlling these parasites is critical for the physical development and overall well-being of affected children 1 .
To understand the true scale of the problem, let's look at a recent cross-sectional study conducted in the Elemere area, a poor rural community in Nigeria, which provides a relevant model for the situation in similar settings, including rural Anambra 7 .
The objective of this study was to determine the prevalence of intestinal parasitic infections and identify key socio-environmental risk factors among school children 7 .
Children were provided with sterile, wide-mouth bottles and instructed to collect early morning stool samples on three alternate days to ensure sample quality.
The samples were transported to a laboratory and examined by skilled technicians using both direct saline-iodine mounts (to observe motile parasites) and the formol-ether concentration technique (a method to concentrate any parasites present, making them easier to find).
Researchers administered questionnaires to parents to gather data on demographic and environmental factors, such as source of drinking water and type of toilet facility used 7 .
The results from the 250 children studied painted a clear picture of the challenge.
The study found that nearly one in four children was infected with at least one intestinal parasite 7 .
The data shows that the roundworm, Ascaris lumbricoides, was by far the most common parasite, accounting for over half of all infections 7 .
Crucially, statistical analysis revealed that rural domicile was significantly associated with parasitic infections 7 . The majority of infected children lived in households that relied on well water (72.8%) and used pit latrines (46%), highlighting the critical role of clean water and improved sanitation in preventing these diseases 7 .

Combating intestinal parasites requires a specific set of tools and techniques, both for diagnosis and for treatment. The fight is waged in community schools and rural health clinics with a practical arsenal.
A laboratory technique used to concentrate parasite eggs and cysts from a stool sample, making them easier to identify under a microscope. This increases the test's sensitivity.
The cornerstone of diagnosis. A technician examines a treated stool sample under a microscope to visually identify the characteristic eggs, cysts, or trophozoites of different parasites.
The large-scale distribution of deworming medications, such as praziquantel (for schistosomiasis) and albendazole/mebendazole (for soil-transmitted helminths), to at-risk populations, often through school-based programs.
Teaching children and communities about the importance of handwashing with soap, using proper toilets, and wearing shoes to prevent parasite transmission.
While intestinal parasites are a primary concern, the parasitic landscape in Nigeria is complex. Research in Anambra State has also highlighted the persistent challenge of urogenital schistosomiasis, a parasitic disease caused by Schistosoma haematobium 8 .
This parasite is not transmitted through contaminated soil, but through contact with freshwater contaminated with cercariae (infective larvae) released by snails.
It causes symptoms like blood in urine, and in females, it can lead to a neglected condition called female genital schistosomiasis (FGS), which has serious long-term consequences for reproductive health 8 .
A 2023 study of adolescents in Anambra State found a UgS prevalence of 14.5%, indicating that this water-borne parasite remains a significant threat alongside the soil-transmitted worms 8 .
The battle against intestinal parasites in Anambra's children is being waged on multiple fronts. The evidence is clear: controlling these parasites is fundamental to ensuring children can lead healthy, productive lives. Success requires an integrated approach:
Continued mass drug administration programs in schools are crucial to reduce the worm burden in children 8 .
Providing access to clean drinking water and improved sanitation facilities is the ultimate long-term solution to break the cycle of transmission 7 .
General health education that emphasizes cleanliness, personal hygiene, and sanitation is vital to empower communities to protect themselves 7 .
With a committed focus on these strategies, the unseen enemy can be defeated, allowing a new generation in Anambra to grow, learn, and thrive without the shadow of parasitic disease.
