In rhesus monkeys, virus detected in cerebrospinal fluid, lymph nodes long after infection
Zika virus plays hard to get.
Weeks after the virus disappears from the bloodstream, it still lingers in the lymph nodes and the central nervous system of rhesus monkeys, researchers report online April 27 in Cell. That could help explain why Zika infection can cause neurological problems in both infants and adults.
“Zika does stick around for a lot longer than we originally thought,” says Dan Streblow, a virologist at Oregon Health & Science University in Portland who wasn’t involved in the study. Streblow’s lab recently reported in PLOS Pathogens that Zika can also linger in rhesus monkeys’ reproductive tracts and peripheral nervous systems. And recent studies in humans have shown evidence of the virus hanging around in semen (SN Online: 2
