Multi-drug resistant tuberculosis in Finland--a forecast

Area of Science:

• Epidemiology
• Public Health
• Spatial Analysis

Background:

• Increased travel post-Soviet system collapse links St. Petersburg, Baltic states, and Finland.
• Growing tuberculosis (TB) and multi-drug resistant TB (MDR-TB) epidemics pose an epidemiological threat to Finland.

Purpose of the Study:

• To forecast the spatial development of a potential MDR-TB epidemic in Finland.
• To model a "worst-case" scenario for MDR-TB spread over a short term.

Main Methods:

• Chorological multistep procedure combining statistical and geographical methods.
• Simulation technique focusing on spatial process drivers rather than population dynamics.
• Risk assignment to small-area units based on socioeconomic and structural characteristics.

Main Results:

• Simulated 6-year cumulative distribution shows MDR-TB case concentration in the capital region.
• A cluster of municipalities along the west coast also shows a high concentration of cases.
• Socioeconomic factors and international contacts are key drivers of epidemic spread.

Conclusions:

• Finland faces a significant epidemiological threat from MDR-TB due to increased cross-border travel.
• Spatial forecasting highlights high-risk areas for MDR-TB, aiding targeted public health interventions.
• Both socioeconomic conditions and international connectivity are crucial in shaping MDR-TB epidemic patterns.
