TB Class Arrivals
All immigrants and refugees (PDF:43KB/10 pages) are required to have a medical examination, including TB screening, before entering the United States. Panel physicians designated by the U.S. Department of State provide these examinations in the person's country of origin using standardized protocols.
Those with TB-related findings that do not prohibit them from entering the United States but need medical follow-up after arrival in the U.S. are given a TB class designation by the overseas panel physician. The U.S. Centers for Disease Control and Prevention (CDC) notifies the Minnesota Department of Health (MDH) of TB Class arrivals coming to Minnesota. MDH then notifies the local public health department in the county where each individual will be living.
MDH and local health departments collaborate to ensure that TB Class arrivals receive follow-up medical evaluations in a timely manner.

MDH is notified of these arrivals and work with local public health agencies to ensure uninterrupted treatment and other necessary medical follow-up.
