The Zika virus outbreak spreading through the Americas could go on for three years, according to a new study published in the journal Science.
Scientists from Imperial College London and Johns Hopkins Bloomberg School of Public Health estimate that the current Zika epidemic will be “largely over” in Latin America in three years. That’s because so many people are being infected, and therefore become immune to the virus. “Herd immunity will likely then cause a delay of over a decade until further large epidemics are possible,” they write in the study.
