Cost per U.S. Case of Tuberculosis Avoided Under a Screening Program for Indian H-1B and H-4 Nonimmigrant Visa Applicants. Notes: Graph presents the cost per U.S. case of tuberculosis (TB) avoided as the number of U.S. TB cases avoided and correction factor increases. The correction factor was varied between 10 and 100% to account for the potential differences between immigrants and NIVs. In the model, the screening outcomes for immigrants are applied to the NIV population; however, it is possible that the TB prevalence would be lower in the NIV population. The correction factor was applied to the percent of the applicants with evidence of TB (resulting in Class B1 NIV arrivals recommended for U.S. follow-up and cases diagnosed pre-departure). NIV = Non-immigrant visa applicant. H-1B = type of visa for highly skilled workers. H-4 = type of visa from family members of H-1B visa holders
