LONDON — Bacteria resistant to antibiotics have now spread to every part of the world and might lead to a future where minor infections could kill, according to a report published Wednesday by the World Health Organization.

In its first global survey of the problem, WHO said it found very high rates of drug-resistant E. coli bacteria, which causes problems including meningitis and infections of the skin, blood and the kidneys.

WHO’s report also found worrying rates of resistance in other bacteria, including causes of pneumonia and gonorrhea.

Unless there is urgent action, “the world is headed for a post- antibiotic era in which common infections and minor injuries which have been treatable for decades can once again kill,” Dr. Keiji Fukuda warned in a release.

Health experts have long warned about the dangers of drug resistance .

WHO said people should use antibiotics only when prescribed by a doctor, complete the full prescription and never share antibiotics with others or use leftover prescriptions.
