Marmosets as the canary in the coal mine for Zika

New research shows small, New World monkeys called marmosets may be an important animal model for emerging viruses with the potential for harmful effects on fetuses. Establishing animal models for emerging diseases, like Zika, is necessary for the development of vaccines, therapies and diagnostics. Results of a study published in the journal Scientific Reports showed...
