[Tuberculosis among Ukrainian Refugees in Germany - A Comparison of Screening and Reporting Data]

Since the onset of the war in Ukraine until November 2022, nearly 1 million people sought refuge in Germany. Despite efforts to reduce tuberculosis (TB) cases, Ukraine had a high TB incidence in 2020, with increased rates of multidrug-resistant TB. Conflict and war have historically been associated with TB spread due to delays in diagnosis, treatment interruptions, and increased transmission risks. The World Health Organization (WHO) estimated a rise in TB cases in the EU region due to refugee movements. In Germany, screening methods used in testing individuals in communal housing involving chest X-rays or immunological tests were variable. A survey conducted by the DZK within the nationwide TB working group evaluated TB screening methods and results for Ukrainian refugees. Out of 26,196 individuals aged over 15, 48 TB cases were detected, with a higher-than-expected incidence. About 42% of cases were multidrug-resistant TB. The screening findings differed from both the WHO's estimates as well as TB cases reported to the Robert Koch Institut (RKI) in 2022. A preliminary comparison of the numbers is presented here. The differing results emphasize the need for ongoing data collection and analysis to adapt resources and interventions to the evolving TB situation among Ukrainian refugees in Germany, especially considering the ongoing conflict and potential for increased TB cases in the future.
