aViral antigens used in CF test: DENV, dengue virus; YFV, yellow fever virus; SLEV, St. Louis encephalitis virus; WNV, West Nile virus.
bCF titers expressed as reciprocal of highest antibody titer/reciprocal of antigen titer.
cPRN titers expressed as highest serum dilution producing >90% plaque reduction.
