From: Evaluation of underreporting tuberculosis in Central Italy by means of record linkage
Underreporting-rate and immigrants rate trend during the study period (1999–2008). Underreporting rate, in database B patients, during ten years tended to decrease, reaching values of 45% in 2008 (upper line). During the ten years considered, there was a significant increase in the rate of TB diagnosis in immigrants (non Italian cases: 23% in 1999, 62% in 2008) (bottom line).
