The Zika virus outbreak "is now spreading explosively" across the Americas, with 3 to 4 million infections estimated for the region in the next year, as Mother Jones reported Thursday.

The infectious disease, which doctors suspect has caused an increase in microcephaly, is likely linked to this year’s El Niño, a global climate cycle characterized by a band of warm water in the equatorial Pacific. But the Zika virus isn’t the only public health concern El Niño brings. This year’s landscape of infectious disease might be a glimpse into a sicker future.
