Cases with positive anti-ZIKV neutralizing antibodies and anti-DENV IgM in cord serum

Case no. Neonates group Anti-ZIKV IgM ELISA Anti-DENV IgM ELISA ZIKV-DENV PRNT90*
ZIKV DENV-1 DENV-2 DENV-3 DENV-4
1 CA Negative Negative 20 < 10 < 10 < 10 < 10

3 Non-CA Negative Negative 40 < 10 < 10 10 10
4 CA Negative Positive < 10 ND ND ND ND
5 Non-CA Negative Positive < 10 ND ND ND ND

CA = Congenital anomalies; DENV = dengue virus; ND = not determined; PRNT = Plaque reduction neutralization test; ZIKV = Zika virus.

* Value indicates PRNT endpoint at which the highest serum dilution inhibited formation of plaque-forming units by ≥ 90%.
