To sum it up, even if you didn't memorize the whole immunization table, it's easy to remember HBV immunization is done at birth, 1mo, 2mo and 6mo roughly. Also added that the baby is of East Asian decent, and the fact that other infections on the list aren't screened for in the first place in healthy-looking patients, I think it's safe to deduce HBV was the answer here.

I thought Hepatitis B has high prevalence in developing countries, she is from a rural region from China, I got right. Plus Hepatitis B is asymptomatic in new borns.

Of all these viruses, Hep B is the only one that a child, if infected, would be a chronic carrier. Thus we should screen to make sure that we can prevent future risk of cirrhosis, etc.
