Which testing should internationally adopted children receive?

• 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)

Testing internationally adopted children focuses on infections that are commonly encountered in many countries of origin and that can be asymptomatic yet impactful or transmissible. The best initial screening panel includes tuberculosis, hepatitis B and C, syphilis, and HIV. Tuberculosis screening is important because TB exposure is more common in some regions, and recognizing latent TB early allows for treatment to prevent progression to active disease, protecting both the child and household contacts. Testing with a TB skin test or interferon-gamma release assay, followed by chest imaging if positive, is the standard approach. Screening for hepatitis B and C addresses infections that can be contracted perinatally or in childhood and can persist without obvious symptoms. Identifying a hepatitis B infection or vaccination status helps plan long-term care, and detecting hepatitis C enables timely treatment and monitoring. Syphilis is included because congenital or perinatal transmission has occurred in some settings, and early detection with appropriate treatment is essential for preventing complications and further transmission. HIV testing is critical because early identification allows timely management to improve health outcomes and reduces the risk of transmission to family members. Other options, such as tests for malaria or cytomegalovirus or routine measles testing, are not universally indicated as part of the initial standard screen for all internationally adopted children. Malaria testing depends on specific exposure risk and symptoms; cytomegalovirus and measles testing are not routinely screened in asymptomatic adoptees without additional risk or clinical signs.
