Zika Outbreak to End in 2 to 3 Years, Scientists Predict

July 14, 2016

(Reuters) – The Zika outbreak rampaging through Latin America will likely burn itself out in the next two to three years, based on the fact that people develop immunity to the virus after an initial infection, British scientists said on Thursday. The researchers, whose work is published in the journal Science, estimated that infections from the mosquito-borne virus will become so widespread in affected countries that populations will develop what is called “herd immunity.” This occurs when a high percentage of a population has become immune to an infection either through developing natural immunity or through vaccination, making a wider outbreak less likely.
