New coronavirus emerges from bats in China, devastates young swine

A newly identified coronavirus that killed nearly 25,000 piglets in 2016-17 in China emerged from horseshoe bats near the origin of the severe acute respiratory syndrome coronavirus (SARS-CoV), which emerged in 2002 in the same bat species. The new virus, called swine acute diarrhea syndrome coronavirus (SADS-CoV), doesn't appear to infect people, unlike SARS-CoV.
