title: Tuberculosis in newly arrived asylum seekers: A prospective 12 month surveillance study at Friedland, Germany.
abstract: In the European Union tuberculosis prevalence-rates are among the lowest in the world. The prevalence of active tuberculosis in migrant populations has to be analyzed to get valid data on the risk of tuberculosis and for the decision of screening activities.
  
  
  
  Therefore, we prospectively quantified the risk of active tuberculosis among asylum seekers at time of arrival. Investigation was performed as regular part of the admission screenings for people arriving at Friedland, Germany, a primary major receiving center during one year.
  
  
  
  In 11.773 newly arrived asylum seekers 16 X-ray investigations gave the suspicion of active tuberculosis, thereof 11 cases could be verified by culture, thereof 9 cases were classified as microscopically positive. These data translate into rates of 136 per 100.000 suspected cases, 93 per 100.000 verified cases, and finally 76 per 100.000 infectious cases, respectively. Prevalence was higher in asylum seekers coming from Eritrea and Russia compared to the main origins of current migration Syria, Afghanistan, Iraq, Iran, and Lebanon. One case of MDR-tuberculosis could be detected in a migrant from Russia.
  
  
  
  Prevalence rates of tuberculosis in newly arrived asylum seekers are higher than in native European populations. Rates seem to reflect the prevalence in the home countries. X-ray investigation during first examination may help identifying people needing further tests for detecting infectious tuberculosis and therefore may prevent transmission. However due to the low prevalence rates screening procedures have to be reviewed.
