Tuberculosis control programs and challenges in developed cities with intermediate disease burden: China experience

Tuberculosis (TB) remains one of the world’s deadliest infectious disease (1). Historically, it not only posed threats in developing countries, but also affected population in the developed world. From a global perspective, more guidance and focus were prioritized in low-income countries and rural areas due to their high TB burdens. Recently, the World Health Organization (WHO) proposed the End TB Strategy targets (90% reduction in TB incidence and 95% reduction in TB deaths by 2035) and the action framework in low-incidence countries (1,2). However, how to strive for TB elimination in urban areas with intermediate disease burden is still not well understood.
