Objective To assess the desirability of requiring proof of tuberculosis (TB) screening
for nonimmigrant visitors to the United States.
Data Sources Literature review using the MEDLINE database for 1966 to 1999 and the
Lexis-Nexis database for 1998 to 1999 on the terms tuberculosis and transmission, combined with the qualifiers foreign visitors, foreign students, foreign born, and policy. Experts
in TB control from the Centers for Disease Control and Prevention, Atlanta,
Ga, and the Canadian government were consulted. The World Wide Web was searched
using the terms tuberculosis and transmission.
Data Extraction English-language articles with information directly related to control
of TB transmission among foreign-born persons were selected.
Results and Conclusions Eliminating TB in the United States will depend significantly on the
ability to control it within the foreign-born population; however, strict
border screening guidelines used as exclusionary measures can actually worsen
the epidemic. Overseas TB screening of nonimmigrant visitors, who are unlikely
to have active TB and even less likely to transmit it, will be of extremely
low yield, would significantly deviate from the US "open-door" policy for
nonimmigrants, and would have great logistical and political implications.
Foreign-born persons 15 years and older who intend to stay in the United States
are the high-risk population most likely to affect public health and thus
will provide the best yield for TB control resources. Screening and monitoring
the nonimmigrant foreign-born population would divert valuable resources from
now established, successful TB control programs for foreign-born immigrants.
