An 18-month-old boy from Enghien is in critical condition after contracting a severe strain of E. Coli that led to hemolytic uremic syndrome (HUS), a rare but life-threatening condition primarily affecting young children. His grandmother described the rapid deterioration as “like a snake bite,” noting that doctors gave him only a 10 to 30 percent chance of survival without lasting damage.
The child’s symptoms began with vomiting on a Monday evening, initially mistaken for a stomach bug. By Wednesday, he had not urinated all day — a red flag that prompted his parents to seek emergency care. Blood tests confirmed infection with a Shiga-toxin-producing E. Coli strain, likely ingested through contaminated food or water. He was transferred to a specialized hospital where he remains under constant monitoring.
HUS destroys red blood cells, clogs blood flow to the kidneys, and can trigger acute kidney failure within days. In severe cases, it also causes neurological damage, including seizures or coma, and cardiac complications. The boy has since gained 1.6 kilograms due to fluid retention, which his family says causes discomfort and irritability as his brain swells under pressure.
Belgian hospitals, including the Cliniques universitaires Saint-Luc, have issued urgent warnings as warmer weather increases risks of exposure. Undercooked ground meat, raw milk cheeses like mozzarella or burrata, unpasteurized apple juice, and contaminated recreational water are common transmission routes. The infection spreads when fecal matter from cattle contaminates food or water supplies, a risk heightened during barbecues and swimming season.
Although HUS remains rare — affecting fewer than one in 100,000 people annually in Belgium — its consequences can be devastating. Up to half of severe cases result in long-term kidney impairment, and some require dialysis or transplantation. Neurological sequelae, including cognitive deficits or epilepsy, occur in a subset of survivors.
There is no specific antibiotic treatment for HUS; in fact, antibiotics may increase toxin release and worsen outcomes. Care is supportive — managing fluid balance, blood pressure, and dialysis when needed. Clinicians stress early recognition: bloody diarrhea, pallor, decreased urine output, and lethargy warrant immediate medical evaluation.
Prevention focuses on food safety: cooking ground beef to an internal temperature of at least 71°C, avoiding raw milk products for children under six, and ensuring juices are pasteurized. Handwashing after animal contact and before meals is critical, especially in rural or farm-adjacent areas.
The Cliniques universitaires Saint-Luc are participating in an international trial testing a therapy designed to neutralize Shiga toxin before it binds to cells. Whereas promising, the treatment remains investigational and is not yet standard of care.
How does hemolytic uremic syndrome damage the body?
HUS occurs when Shiga toxin from certain E. Coli strains enters the bloodstream and destroys red blood cells, clogs kidney filters with debris, and lowers platelet counts. This triad — hemolytic anemia, low platelets, and acute kidney injury — defines the syndrome. In severe cases, the toxin can cross the blood-brain barrier, causing confusion, seizures, or stroke, and may impair heart function.
Why are young children more vulnerable to HUS?
Children under five have developing immune systems and kidneys that are less able to withstand the toxic effects of Shiga toxin. Their gastrointestinal tracts may also bind the toxin more efficiently, increasing systemic exposure. They are more likely to place hands or objects in their mouths after contact with contaminated surfaces, raising ingestion risk.
