It was part of the workup for a 2002 case in New York where a baby was born with severe birth defects to a woman with West Nile:
Yet this test was not listed as being part of the workup for the babies from Brazil:
I'm wondering why since LCMV is said to have a worldwide distribution and must be in South America since a couple of children in a home for the severely disabled in Argentina tested positive for exposure:
Periventricular calcifications are found in LCMV and in the Brazil babies:
The mothers in the CDC study were screened to have had rashes, I think, but you can have rashes with LCMV, though it is rarer. But LCMV can also be asymptomatic in mothers who have babies with congenital infections. One of the theories about why Zika may have resulted in uncharacteristic damages in Brazil is that there was a co-infection in those cases.
So I am wondering if there could be an epizootic of LCMV going on in Brazil. Too bad CDC didn't test, but maybe there is a reason they ruled it out without testing. I just hope money was not an issue.

...and serologic tests were negative for lymphocytic choriomeningitis virus infection and toxoplasmosis
All 35 infants in the cohort tested negative for syphilis, toxoplasmosis, rubella, cytomegalovirus, and herpes simplex virus infections.
