A new WHO report takes the widest look yet at the problem of antibiotic-resistant bacteria, and the news is not good.

The report goes into detail about some of the problems facing us with increasingly treatment-resistant strains of contagious bacteria. It also includes a number of maps showing how widespread — both in terms of different bacteria and across country borders — the problem is.

But, new antibiotics are coming right? Well, maybe, but as the WHO points out in this timeline, it's been 30 years since the last major new antibiotic was developed, leading to what they call "a discovery void."

So what can we do in the absence of new antibiotics? Mostly use the antibiotics we already have correctly. And, according to the WHO, that means using antibiotics only when they're prescribed, not sharing or using leftover antibiotic prescriptions, and finishing taking your antibiotics until your whole prescription runs out.
