Women who have previously infected with dengue virus may be at greater risk for increased damage to their fetuses and placentas if they then become infected with Zika virus.
A study conducted by the Department of Microbiology at the Icahn School of Medicine at Mount Sinai revealed the shocking reports.
The study ‘Dengue virus immunity increases Zika virus-induced damage during pregnancy’were published in the February issue of Immunity journal.
The research team led by Jean Lim,PhD,Associate professor of microbiology and Co-Director of Microbiology Multidisciplinary Training at the Icahn school of Medicine Mount Sinai,dengue virus specific antibodies into mice prior to infection with Zika virus during pregnancy.
The presence of the antibodies increased placental damage and foetal resorption.The same condition occurred in Zika infected human placenta tissues.
Dr.Jean Lim,the research head said”our research may explain the high rate of microcephaly and birth defects observed in the recent Zika virus outbreaks in South America”.
