School Outbreak in Landen
Health authorities have confirmed a tuberculosis outbreak at a primary school in Landen, Belgium. Eighteen students from a sixth-grade class and one teacher tested positive for the bacterial infection. One student required hospitalization but is now recovering.
Infection Source and Response
Investigations revealed the initial infection came from a family member who contracted TB abroad. According to Flanders' Agency for Care and Health, this index case spread the disease within the classroom environment. Of the 23 students tested, 17 showed latent infections along with their teacher. Two asymptomatic students were referred for further examination.
About Tuberculosis
Tuberculosis (TB) is caused by Mycobacterium tuberculosis bacteria, primarily affecting the lungs. It spreads through airborne droplets when infected individuals cough or sneeze. Only 10% of carriers develop active disease, while others maintain latent infections. Symptoms include persistent cough, fever, night sweats, and weight loss. Treatment involves 6-9 months of antibiotics.
Regional Context
While TB rates remain low in the Netherlands according to RIVM, this outbreak follows recent cases including a PSV Eindhoven footballer diagnosed in March 2025. The World Health Organization recently reported record global TB cases, highlighting ongoing concerns about this ancient disease that still causes over 1.25 million annual deaths worldwide.
School Measures
The school remains open during final-week activities, with health officials monitoring the situation. Additional testing is planned for another class where a student had close contact with the initial case. Authorities emphasize that early-detected TB is fully treatable with modern antibiotics.
