Cover Story: Dengue virus antibody assays frequently cross-react with sera from individuals that were infected with or vaccinated against related flaviviruses. This makes it challenging to monitor the prevalence of dengue virus infections in regions where several flaviviruses co-circulate. The study examined the diagnostic specificity of two dengue virus ELISAs with sera obtained 3-4 weeks or 0.5-6 years after yellow fever virus (YFV) and Japanese encephalitis virus (JEV) vaccination. Sera were from individuals living in a non-endemic area and dengue virus neutralization was used as control for probable dengue virus infection. The two assays showed varying degrees of cross-reactivity. The specificity of one of the assays may be suitable for seroprevalence studies in areas with a high prevalence of dengue virus infections.
