Risk of tuberculosis transmission by children in Hamburg, Germany.

Background: Data from a prospective molecular-epidemiologic study (1997-2021) in Hamburg, Germany, were evaluated to assess the transmission risk of Mycobacterium tuberculosis complex (Mtbc) by children <15 years in a low-incidence setting.

Methods: Isolates of Mtbc were genotyped whole genome sequencing, applying a core genome multilocus sequence typing scheme. Close contacts of culture-confirmed children were examined for latent Mtbc infections (LTBI) with particular focus on IGRA testing.

[Scope of Initial Examinations of Unaccompanied Minor Foreigners: A Nationwide Population Survey].

Background: When unaccompanied minors (UMA) are taken into provisional care by the youth welfare offices, it is legally obligatory to carry out an initial medical examination and obtain a statement as to whether the state of health of minors excludes the implementation of the distribution procedure according to the Königsberg Key and, in the case of 15-year-olds and non-pregnant persons, an X-ray thorax scan to exclude infectious tuberculosis of the lungs. The supreme state health authorities of the German federal states determine the further scope of the investigations. The aim of this nationwide survey is a comparison of the different concepts of the individual states with regard to the scope of the initial UMA investigations.
