I know, I know: Another end-of-the-year list. But what can I say—it’s tradition. Here are the top plague stories from 2015, in no particular order:
1) Scientists discovered new drug-resistant bacteria in China that can withstand colistin—the last antibiotic that could fight dangerous resistant bacterial strains. For great reporting on the findings and their implications, check out this piece by Mary McKenna at National Geographic and this one by Helen Branswell at Stat.
3) Ebola fell and then flared up again—sometimes within the same country. Here's Sarah Zhang at Wired on what went wrong with the global response to the 2014 outbreak and an insightful interview on how to prevent the next one by Julia Belluz at Vox.
7) Nigeria hit a key milestone in the global effort to eradicate polio: the country is more than a year free of wild strains. Many challenges stand in the way of ridding the two remaining countries—Afghanistan and Pakistan—of the virus, according to Maureen Taylor at Quartz.
