Long commutes on crowded public transport in Cape Town may worsen tuberculosis spread. This study measures carbon dioxide (CO2) levels to assess the risk of TB transmission during extended travel times.

Area of Science:

  • Environmental Health
  • Epidemiology
  • Public Health Policy

Background:

  • South Africa faces a severe global tuberculosis (TB) epidemic.
  • Factors contributing to TB spread include high HIV prevalence, inadequate TB control, and poor indoor ventilation.
  • Historical factors like racial capitalism, mining, and migration, alongside forced removals, shape current public health challenges.

Purpose of the Study:

  • To investigate the role of extended commutes in propagating the TB epidemic in Cape Town.
  • To measure carbon dioxide (CO2) levels in public transport as an indicator of ventilation and potential TB transmission risk.

Main Methods:

  • Monitoring CO2 concentrations within public transport vehicles.
  • Analyzing the relationship between commute duration, CO2 levels, and potential TB transmission pathways.

  • Linking transport conditions to the legacy of forced removals and peri-urban settlement patterns.

    • Main Results:

    • Elevated CO2 levels were observed in public transport, indicating poor ventilation.
    • Extended commutes associated with peri-urban living increase exposure duration in these environments.
    • This highlights a potential, understudied vector for TB transmission in Cape Town.

    Conclusions:

    • Crowded, poorly ventilated public transport during long commutes presents a significant risk factor for TB transmission in Cape Town.
    • Addressing transport-related environmental factors is crucial for effective TB control strategies.
    • Policy interventions should consider the impact of urban planning and historical inequities on infectious disease spread.
