Hemolytic Uremic Syndrome
8 cases in 2024 (baseline: ~21). Low absolute count.
What is it?
Hemolytic Uremic Syndrome (HUS) is a life-threatening complication that occurs in about 5–10% of people infected with Shiga toxin-producing E. coli (STEC). NYS had 8 cases in 2024. HUS involves hemolytic anemia (destruction of red blood cells), thrombocytopenia (low platelets), and acute kidney failure. It is the most common cause of sudden kidney failure in children in the United States.
How it spreads
HUS itself is not contagious — it is a complication of STEC infection. STEC spreads through undercooked ground beef, unpasteurized dairy, contaminated produce, animal contact, and person-to-person fecal-oral transmission.
Symptoms
Follows a diarrheal illness (often bloody). Warning signs typically appear about a week after diarrhea begins: decreased or no urination, extreme fatigue, pale skin and pale inner eyelids, easy bruising, and swelling. Seizures can occur.
Who is at risk?
Young children under 5 are at highest risk for developing HUS after STEC infection. Elderly adults and immunocompromised individuals are also at elevated risk.
What you can do
Based on NYSDOH annual communicable disease report. Threat level reflects 2024 case counts compared to the 5-year baseline.
