Shanghai is grappling with an increase in tuberculosis (TB) cases as its population of individuals aged 65 and above continues to grow. This demographic shift presents significant challenges for public health officials aiming to control the spread of TB in the bustling metropolis.
Demographic Shifts Impact TB Trends
Between 2015 and 2023, Shanghai reported nearly 30,000 TB cases, with men representing nearly 70% of these infections. Notably, in 2023 alone, the TB notification rate soared to 19.55 per 100,000 people, with the highest incidence found in those aged 65 and older, where the rate peaked at 48.47 per 100,000. Each year, a larger proportion of TB patients belong to the elderly demographic, signaling a troubling trend for the city’s health infrastructure.
Future Projections Highlight Control Challenges
Forecasts using grey models and age-period-cohort analyses suggest that TB cases among the elderly will continue to rise, particularly in the 70-79 age bracket over the next five years. Under scenarios where the aging population expands, the reduction in TB notification rates slows significantly, indicating that current control measures may not suffice to curb the epidemic effectively.
• The elderly population is becoming the most affected group by TB in Shanghai.
• Current TB control strategies may need reevaluation to address the growing elderly demographic.
• Projections indicate a potential plateau in TB rate reductions if aging trends continue unabated.
• Gender disparities persist, with males disproportionately affected by TB.
Addressing the surge in TB cases among Shanghai’s elderly requires targeted interventions tailored to this vulnerable group. Strengthening healthcare services, enhancing screening programs, and implementing age-specific treatment protocols could mitigate the impact of TB in an aging population. Additionally, public health policies must adapt to demographic changes to ensure sustainable control of infectious diseases like TB. By prioritizing resources and strategies for older adults, Shanghai can better manage its TB burden and safeguard the health of its aging residents.
