Superbugs evolve in a few ways. When bacteria grow and spread, they can develop mutations in their DNA that make them resistant to certain types of drugs.
While plague in Madagascar is not unusual, the 2017 Madagascar plague outbreak was one of the most severe in recent history. As serious as this public health threat is, the World Health Organization (WHO) and the Centers of Disease Control and Prevention (CDC) are trying to calm the hysteria being fueled by exaggerated claims in popular media.
Bacteria are constantly evolving, so even if we are able to develop an arsenal of new drugs, we will always need to stay one step ahead of the bugs. For that reason, we need to use diagnostics tests to help doctors prescribe antibiotics more accurately.
