Rising number of tuberculosis cases among Tibetans in New York City.

Tuberculosis among Tibetans increased in New York City between 1995 and 1999. We examined characteristics of 68 Tibetan patients compared to 702 non-Tibetan patients from Nepal, India, or China, diagnosed between January 1995 and December 1999. The number of Tibetan patients increased each year after 1995 whereas non-Tibetans remained stable during the same period. Tibetans were younger (27 vs. 44 years), more likely to be infectious (63% vs. 46%), have multidrug resistance (7% vs. 2%) and shorter time to diagnosis after arrival (9 vs. 79 months, p < 0.01). For Tibetan patients, 68% of identified contacts were evaluated. The prevalence of tuberculosis infection was 65%. In contrast, among non-Tibetan patients 88.8% of contacts were evaluated and 45.2% were infected. Outreach efforts with community leaders and educational presentations at community events have been implemented in an effort to ensure continuity of care and completion of treatment.
