Context:
Recent tuberculosis (TB) epidemiology in Japan shows concerning trends.
A plateau in the incidence of bacteriologically confirmed TB cases.
An increasing incidence of smear-positive TB cases among the elderly population.
Purpose:
To analyze recent trends in Japan's tuberculosis epidemiology.
To investigate the reasons behind the slowing decrease in TB incidence.
To assess the future prospects of TB elimination in Japan.
Summary:
The decreasing trend of tuberculosis incidence in Japan has slowed, with bacteriologically confirmed cases remaining constant and smear-positive cases rising in older adults.
These epidemiological shifts, coupled with a significant generation gap in TB infection prevalence, threaten Japan's goal of TB elimination.
Current chemoprophylaxis coverage is low (estimated 15%), highlighting the need for enhanced contact tracing and examination strategies.
Impact:
The findings suggest that current TB control strategies may be insufficient to achieve elimination.
Future TB microepidemics are a growing concern due to generational differences in infection prevalence.
Increased emphasis on contact examination is crucial for future TB control efforts in Japan.
