reporting, particularly among people who had not received a diagnosis and cases
managed by healthcare facilities that did not consistently report their data. In 2023,
approximately 140,000 people with TB were estimated to remain undiagnosed, emphasizing
the importance of improving surveillance and access to diagnostic services (WHO, 2025a).
Several factors contribute to the continued transmission of TB in Indonesia.
Overcrowded housing, inadequate ventilation, poverty, undernutrition, and limited access to
healthcare can increase vulnerability to infection or delay diagnosis. In addition, people living
with HIV, individuals with diabetes, and those with weakened immune systems have a higher
risk of developing active TB disease. Social stigma and misconceptions about the disease may
also discourage individuals from seeking medical assistance or disclosing their condition to
healthcare providers. Consequently, TB control requires more than medical treatment; it also
requires improvements in living conditions, public health education, social support, and
equitable access to healthcare (WHO, 2026).
The consequences of TB extend beyond physical illness. Untreated or inadequately
treated TB can lead to severe complications, disability, and death. The disease may also affect
educational participation, employment, household income, and family well-being. Patients and
their families may experience financial difficulties because of transportation expenses, time
away from work, and other indirect costs associated with treatment. In addition, stigma can
contribute to social isolation and emotional distress. Therefore, TB prevention and control
should address both the clinical needs of patients and the broader social circumstances that
influence their health outcomes.
Early diagnosis is a critical component of TB control. WHO recommends rapid
diagnostic tests for individuals with signs and symptoms of TB because these tests can help
identify the disease and guide treatment decisions. Depending on the clinical situation,
healthcare professionals may also use sputum examination, chest X-rays, and other
investigations. In Indonesia, strengthening the role of primary healthcare facilities, including
Puskesmas, is important for improving access to screening, diagnosis, referral, and follow-up
services. Community-based case finding and more effective reporting systems can also help
identify individuals who might otherwise remain undiagnosed (WHO, 2025; WHO, 2026).
TB is preventable and curable when appropriate care is provided. Treatment for active
TB disease generally involves a combination of antibiotics taken over several months, with the
regimen and duration determined by healthcare professionals according to the patient's
condition and the drug susceptibility of the bacteria. Patients must follow the prescribed
treatment plan and attend scheduled medical evaluations. Stopping treatment prematurely or
taking medication inconsistently can contribute to treatment failure, relapse, and drug
resistance. Drug-resistant TB is particularly concerning because it requires specialized
treatment and can be more difficult to manage. Healthcare workers, family members, and
treatment-support programs play an important role in helping patients complete therapy safely
and successfully (WHO, 2026).
Prevention requires coordinated action at individual, community, and national levels.
Individuals should seek medical evaluation when experiencing symptoms suggestive of TB,
