How big a threat are superbugs?
A major review of resistance to antibiotics has warned that by 2050, superbugs could kill one person every three seconds across the world unless urgent action is taken.
The Review on Antimicrobial Resistance, started in mid-2014, calls for a public awareness campaign to stop people taking antibiotics when there is no need.
The Victoria Derbyshire programme looks at the battle against infections that are resistant to drugs.
