Tuberculosis trends in Madrid, 1994-2003: impact of immigration and HIV infection
1Consejería de Sanidad y Consumo, Hospital Gregorio Marañon, Madrid, Spain.
Setting:
Tuberculosis (TB) cases reported from nine districts of Madrid, where the percentage of immigrant population varied from 1.9% in 1996 to 12.2% in 2003.
Objective:
To describe the trends in TB incidence from 1994 to 2003.
Design:
Observational study.
Results:
Between 1994-1995 and 2002-2003, the TB rate decreased from 48.5 (95% CI 45.8-51.1) to 23.3 per 100000 population (95% CI 21.5-25.1) (P < 0.001). The percentage of TB cases co-infected with HIV decreased from 55.9% in 1994 to 14.3% in 2003 (P < 0.001), whereas TB cases in foreigners increased from 2.6% in 1994 to 33.7% in 2003 (P < 0.001).
Conclusion:
Although the TB rates showed a marked decrease in the study period, the increasing impact of immigration contributed to slowing down the trend.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
