A new drug-resistant fungus that originates from Japan has infected more than 200 patients in England, according to reports.
According to the BBC, hospitals are on the lookout for further cases and are putting in place measures to help control any further spread of the fungus, which is called Candida auris.
Public Health England says in some cases patients will have no symptoms, but the infection can cause serious bloodstream and wound infections.
The first UK case emerged in 2013, but so far no patient has died from it here.
Twenty NHS Trusts and independent hospitals have detected the fungus, which has developed some resistance to the drug doctors normally use against it.
Three hospitals have seen large outbreaks that have been difficult to control, despite intensive infection prevention and control measures.
Dr Colin Brown, from Public Health England's national infection service, told the BBC: "Our enhanced surveillance shows a low risk to patients in healthcare settings. Most cases detected have not shown symptoms or developed an infection as a result of the fungus.
"NHS hospitals that have experienced outbreaks of Candida auris have not found it to be the cause of death in any patients."
