Factors Associated with the Incidence of Cholera Among Children Aged 0–18 Years: A Case Study of Kanyama Level 1 Hospital During the 2023–2024 Period, Lusaka, Zambia
This retrospective study of 138 children at Kanyama Level 1 Hospital in Zambia (2023–2024) identifies that cholera incidence is significantly driven by younger age, large household size, low parental education, treatment delays, and environmental factors such as unsafe water sources and inadequate sanitation, highlighting the urgent need for targeted interventions in education, water safety, and healthcare access.

Cholera is a severe diarrheal illness caused by a specific bacterium that thrives when people drink water contaminated with feces. It spreads most easily in places where clean water is scarce and where sewage systems are broken or missing, allowing waste to mix with drinking sources. While the disease can affect anyone, it hits children the hardest because their bodies are smaller and less able to withstand the rapid dehydration that the illness causes. In many parts of the world, particularly in crowded urban areas with poor infrastructure, outbreaks are a recurring tragedy. Understanding exactly which conditions allow this disease to take hold in children is not just an academic exercise; it is the key to stopping the cycle of infection and saving lives.
In the bustling, densely packed township of Kanyama, just outside the center of Lusaka, Zambia, researchers set out to understand why children were falling ill with cholera so frequently. They focused their study on the period from late 2023 through 2024, looking back at the medical records of 138 children, aged zero to eighteen, who had been admitted to the local Kanyama Level 1 Hospital with confirmed cases of the disease. By examining the details of these children's lives—their ages, the size of their families, their parents' education, and the water they drank—the team aimed to pinpoint the specific factors that made some children far more likely to get sick than others.
The investigation revealed that the youngest children were the most vulnerable. Those under the age of five made up nearly half of all the cases, and they were significantly more likely to contract the disease than older children. The study found that living in a large household also played a major role; children in homes with more than eight people faced more than double the risk of infection compared to those in smaller families. This suggests that overcrowding creates an environment where the bacteria can spread quickly from person to person. Furthermore, the education level of the parents mattered deeply. Children whose parents had less formal schooling were almost twice as likely to get cholera, pointing to the critical link between knowledge about hygiene and the ability to prevent disease.
Beyond the home, the study highlighted that how and when families sought help was just as important as where they lived. When parents delayed taking a sick child to the hospital, the risk of severe outcomes rose sharply, nearly tripling the danger. The most common reason for these delays was simply the distance to the medical facility, which acted as a barrier to timely care. On the environmental front, the source of drinking water was a decisive factor. Families that relied on untreated water from community wells or streams faced a much higher risk than those who treated their water. Specifically, the practice of adding chlorine to water, which kills the bacteria, cut the risk of infection in half. Conversely, the lack of proper toilets was a major driver of the outbreak; households that practiced open defecation, where waste is left in the open rather than in a latrine, were strongly linked to higher rates of cholera.
The researchers concluded that cholera in this community is not caused by a single mistake, but by a combination of demographic, social, and environmental pressures. The disease flourishes where young children live in crowded conditions, where parents lack resources or education to maintain safe hygiene, and where the local infrastructure fails to provide clean water and sanitation. The data showed that while the bacteria is the immediate cause, the real drivers are the conditions that allow it to spread: unsafe water, untreated waste, and delays in getting medical help. The study makes it clear that to protect children in places like Kanyama, efforts must go beyond just treating the sick; they must include improving access to clean water, ensuring families can treat their water at home, building better sanitation facilities, and making sure medical care is close enough to reach in an emergency.
