Previous flavivirus infection could help explain the severity of symptoms in some people infected during the ongoing Zika outbreak, researchers report.

Scientists at Florida Gulf Coast University and their colleagues have found that human cells were more likely to be infected with Zika virus in vitro if they contained antibodies to dengue virus. Their findings, detailed Monday (April 25) in a bioRxiv preprint, could help explain why Zika infection appears to be more severe in areas where dengue is endemic, and points to a potential unintended effect of dengue vaccination.
Antibodies to dengue can increase the virus’s infectivity for certain types of immune cells through a process called antibody-dependent enhancement (ADE), resulting in the production of more virus and more severe illness.
