TB Preventive Treatment Protection Wanes After One Year in High-Burden Nations

A study published in The Lancet Respiratory Medicine indicates that protection from tuberculosis preventive treatment wanes after one year in high-burden settings.

While TPT offers strong initial protection during the first 12 to 24 months, long-term protection lasts up to eight and 13 years in medium- and low-burden countries.

Researchers suggest high-burden nations combine antibiotic preventive courses with broader interventions addressing community transmission.
