CHICAGO (Reuters) - Prior infection with West Nile or dengue - two viruses closely related to Zika - can make Zika symptoms worse, U.S. researchers said on Thursday.
The findings in mice, published in the journal Science, confirm studies in cells suggesting that prior infection with dengue could worsen the effects of Zika.
That could explain higher rates of severe Zika side effects, such as the birth defect microcephaly, in areas such as Brazil, where dengue is common. It also raises concerns about current or experimental dengue vaccines by Sanofi, Takeda Pharmaceutical Co, GlaxoSmithKline and others because they could inadvertently make Zika infections worse.
