Our generation has been lucky enough to live through a golden age in medicine – the age of antibiotics, where drugs to kill bacterial infections off quickly are readily available. Now, though, growing numbers of bacteria are becoming resistant to our most powerful drugs, evolving into new strains – often called ‘superbugs’ – that we can no longer kill. Already drug resistance kills over 700,000 people globally every year and if we fail to tackle the problem it could cause an extra 10 million deaths a year by 2050.
New antibiotic drugs are proving difficult to find – but there is a completely different approach to killing bacteria that may prove vital in saving us from infections: using viruses.
