First-year diagnoses§ 208 259 (204–294) −19.7 NA NA NA
Persons with class B TB# 4,827 7,169 (6,705–7,582) −32.7 25,736 22,953 (20,876–25,055) 12.1

*Data for TB cases and first-year diagnoses are from National TB Surveillance System; data for Class B TB are from CDC’s Electronic Disease Notification system (9). First-year diagnoses are those of persons who received a diagnosis of TB disease within 12 months of arrival to the United States. Persons with Class B TB are those screened overseas before arrival who are recommended to have a postarrival evaluation for TB in the United States. NA, not available; TB, tuberculosis. †Bootstrap prediction interval. ‡Predicted (counterfactual) frequencies for 2020 and 2023 were estimated from Poisson models using data from NTSS during 2010–2019 (3). §Data for 2023 were not available at the time of analysis. #Predicted frequencies for 2020 and 2023 were estimated from a Poisson model using data from EDN during 2010–2019 (9).
