Zika: New Risks Discovered
Much of the concern about Zika virus has focused on infection during pregnancy and the increased risk for serious birth defects like microcephaly. Now, for the first time, findings of a new study indicate the adult brain also may be affected by Zika.
In a study involving adult mice, areas of the brain related to learning and memory appeared vulnerable to the virus. Until now, Zika infection in adults who did not conceive around the time of the infection was thought to be mild—usually causing just minor symptoms.
According to researchers, the neurological effects of Zika in adults may be subtler than in newborns. More research is needed to confirm or disprove these findings in humans, and, if confirmed, determine the long-term effects of Zika infection in adults.
