Is Universal Screening Necessary? Incidence of Tuberculosis among Tibetan Refugees Arriving in Calgary, Alberta

Figure 1

Screening for Tibetan refugees between 2014 and 2016. 100 percent of Tibetan refugees are assessed for active TB within 30 days of arrival in Canada at Calgary TB Services. One patient was excluded for age over 50 years with no additional risk factors for reactivation TB, two patients had history of extrapulmonary TB, thirteen patients had history of treated pulmonary TB, and one patient had history of NTM infection treated with sufficient duration of rifampin to constitute treatment for LTBI. Some patients had been assessed by Calgary Refugee Clinic or a primary care center where they had received LTBI screening with TST.
