USCIS Doctors Infectious Disease Screening 2 — Questions and Answers
Question 1: What does a Class B1 tuberculosis designation mean in the immigration context?
- Pulmonary TB, active but not suspected infectious, or TB requiring follow-up evaluation (Correct answer)
- TB that is fully cured with no follow-up needed
- Extrapulmonary TB only
- Latent TB with no chest X-ray abnormality
Correct answer: Pulmonary TB, active but not suspected infectious, or TB requiring follow-up evaluation
Class B1 TB designates pulmonary TB that is active but not currently suspected to be infectious, or cases that require further evaluation.
Question 2: Hansen's disease (leprosy) is a Class A communicable disease for immigration purposes. Which form of the disease triggers inadmissibility?
- Infectious (lepromatous) leprosy (Correct answer)
- Non-infectious (tuberculoid) leprosy
- Any form of leprosy regardless of infectivity
- Only leprosy with documented transmission
Correct answer: Infectious (lepromatous) leprosy
Only infectious (lepromatous) leprosy is classified as a Class A condition; non-infectious forms are classified as Class B.
Question 3: Which sexually transmitted infection, when in its infectious stage, is classified as a Class A condition for immigration?
- Syphilis, infectious stage (primary or secondary) (Correct answer)
- Herpes simplex virus (HSV)
- Chlamydia
- Human papillomavirus (HPV)
Correct answer: Syphilis, infectious stage (primary or secondary)
Primary and secondary syphilis (infectious stages) are classified as Class A communicable diseases of public health significance for immigration purposes.
Question 4: What should a civil surgeon do if an applicant has a positive IGRA result but a normal chest X-ray?
- Classify as Class B2 (latent TB infection) and document appropriately on Form I-693 (Correct answer)
- Classify as Class A active TB and recommend inadmissibility
- Repeat the IGRA and withhold the form pending results
- No further action is needed if the chest X-ray is normal
Correct answer: Classify as Class B2 (latent TB infection) and document appropriately on Form I-693
A positive IGRA with a normal chest X-ray indicates latent TB infection, classified as Class B2, which does not render an applicant inadmissible.
Question 5: An immigration applicant tests positive on the initial RPR syphilis screen. What is the next required step?
- Perform a confirmatory treponemal test (e.g., FTA-ABS or TP-PA) (Correct answer)
- Immediately classify as Class A and recommend treatment
- Repeat the RPR test twice before confirming
- Refer to infectious disease specialist before completing Form I-693
Correct answer: Perform a confirmatory treponemal test (e.g., FTA-ABS or TP-PA)
A reactive RPR must be confirmed with a treponemal-specific test to distinguish true syphilis from biological false-positive reactions.
Question 6: Which communicable diseases are classified as 'quarantinable diseases' by executive order and are automatically Class A for immigration?
- Cholera, plague, smallpox, yellow fever, and viral hemorrhagic fevers (Correct answer)
- Influenza, hepatitis A, and norovirus
- HIV, hepatitis B, and hepatitis C
- Measles, mumps, and rubella
Correct answer: Cholera, plague, smallpox, yellow fever, and viral hemorrhagic fevers
Executive Order 13295 designates cholera, plague, smallpox, yellow fever, and viral hemorrhagic fevers as quarantinable diseases, all of which are Class A for immigration.
