Internationally adopted children should be tested for which combination of infections?

• A. syphilis, cytomegalovirus, hep A and C, HIV
• B. tuberculosis, hep B and C, syphilis, HIV
• C. measles, hep A and C, cytomegalovirus, malaria
• D. measles, hep A and C, tuberculosis, malaria

Answer: (B)

Screening internationally adopted children focuses on infections that can be silent yet have serious long-term effects, especially because prevalence varies by country of origin. The most important set to screen for includes tuberculosis, hepatitis B and C, HIV, and syphilis. Tuberculosis testing helps identify latent infection that could later become active and spread to others; using a tuberculin skin test or an IGRA plus chest imaging if positive guides timely treatment and prevents transmission. Hepatitis B and C are screened because chronic infection can develop and cause liver disease over time, and identifying infection early allows appropriate care and monitoring. Hepatitis B testing typically looks for markers of infection and immunity to determine current infection vs. immunity from past exposure or vaccination. HIV testing is essential because early treatment improves health outcomes and reduces transmission risk. Syphilis testing is important due to exposure risk in various regions and the potential consequences of congenital or early-life infection; identifying and treating syphilis early prevents serious complications. Other infections like measles or malaria, or vaccines such as hepatitis A, are not routinely screened in all internationally adopted children. Measles and malaria concerns are more often addressed through vaccination strategies and symptom-based testing or region-specific risk assessment, while malaria testing is usually prompted by fever or travel history rather than universal baseline screening.
