An American woman who travelled to India died after contracting a superbug resistant to all forms of antibiotic, doctors have said.
The victim, aged in her 70s, died in Nevada after medics in the US were unable to find any drug that could treat her.
A report into the incident says it is believed she contracted the superbug NDM-1.
“The patient developed septic shock and died in early September,” it read.
“During the two years preceding this US hospitalization, the patient had multiple hospitalizations in India related to a right femur fracture and subsequent osteomyelitis of the right femur and hip; the most recent hospitalization in India had been in June 2016,”
The lethal bug NDM-1 first came to the attention of doctors in Britain around 2010.
Scientists writing in the journal Lancet Infectious Diseases said there had been 37 cases in the UK of a bug resistant to all antibiotics.
All patients had travelled from Asia after cosmetic surgery, cancer treatment and transplants.
New Delhi-Metallo-1 (NDM-1) also has an “alarming potential to spread and diversify.”
Experts said there are currently no drugs in development to counter NDM-1 meaning it was likely to spread.
Randall Todd of the Washoe County, Nevada health department, said: “We have a shrinking world.
“Hospitals should be reminded that they have got to take a travel history and be open to the possibility that an uncommon infection might be responsible.”
