Dengue immunity may be protective against symptomatic Zika, study finds

(NIH/National Institute of Allergy and Infectious Diseases) Children with a history of prior dengue virus infection had a significantly lower risk of being symptomatic when infected by Zika virus, according to a study in Nicaragua of more than 3,000 children aged 2 to 14 years. Experts have worried that prior dengue virus infection could exacerbate severe Zika disease. However, the new findings, published in PLOS Medicine, indicate that prior dengue immunity in children may in fact be protective against symptomatic Zika disease.
