N2 - BACKGROUND: Immigrants have been contributing to the incidence of tuberculosis (TB) in Germany for many years. The current wave of migration of asylum seekers to Germany may increase that figure. Healthcare workers (HCW) who look after refugees not only in hospitals and medical practices but also in aid projects may be exposed to cases of TB.METHODS: The incremental TB cases arising from imported TB as well as from TB cases that developed later in refugees were calculated in a Markov model over a period of 5 years. Infectious and non-infectious susceptible TB and multidrug-resistant TB (MDR-TB) cases were determined separately. In addition, the total amount of latent TB in contact persons and the risk of infection by HCW were estimated. Due to uncertainty of future refugee flows to Europe, different scenarios were considered in univariate and multivariate sensitivity analysis.RESULTS: Assuming a decrease in immigration by half each year to the bottom line of 2014, and in light of the current number of 800,000 asylum seekers, we calculated an additional 10,090 TB cases by the end of the fifth year (5976 cases of infectious pulmonary TB and 143 cases of pulmonary MDR-TB). In case of an unchanging influx of asylum seekers over the 5-year period, 19,031 TB cases would arise, 377 of which infectious MDR-TB. Eighty -seven ensuing TB cases would develop in HCW in the same period, 3 of which MDR-TB cases.CONCLUSIONS: Although the total number of TB cases in HCW expected to ensue from the current influx of asylum seekers is rather small, the 3 MDR-TB cases we calculated have to be taken seriously. We consider it essential to increase awareness of protective measures such as respiratory masks and, in the event of documented exposure, of supply-oriented occupational health screening.
