Eurosurveillance has published High rate of transmission in a pulmonary tuberculosis outbreak in a primary school, north-eastern Italy, 2019. The abstract:
Italy is a low-incidence country for tuberculosis (TB). We describe a TB outbreak in a primary school in north-eastern Italy, involving 10 cases of active pulmonary disease and 42 cases of latent infection.
The index case was detected in March 2019, while the primary case, an Italian-born schoolteacher, was likely infectious since January 2018.
Administration of a pre-employment health questionnaire to school staff with sustained contact with children should be considered in low-incidence countries.
