The world is entering an era where injuries as common as a child's scratched knee could kill, where patients entering hospital gamble with their lives and where routine operations such as a hip replacement become too dangerous to carry out, the head of the World Health Organisation (WHO) has warned.
There is a global crisis in antibiotics caused by rapidly evolving resistance among microbes responsible for common infections that threaten to turn them into untreatable diseases, said Margaret Chan, director general of the WHO.
Addressing a meeting of infectious disease experts in Copenhagen, she said that every antibiotic ever developed was at risk of becoming useless.
"A post-antibiotic era means, in effect, an end to modern medicine as we know it. Things as common as strep throat or a child's scratched knee could once again kill."
