The first confirmed case of monkeypox has been identified in Ireland, health officials said.
The infection was reported on Friday night in the east of the country and the affected person was not hospitalized.
A second suspected case of smallpox is also being investigated and test results are expected, the Health Service Executive (HSE) said.
A public health risk assessment has been carried out and people who have been in contact with the person should be advised what to do in case of illness.
The HSE said the confirmed case in Ireland “was not unexpected” after infections in the UK and many European countries.
Sixteen more cases were identified in England on Friday.
The UK Health Security Agency (UKHSA) said the new cases bring the total to England from 7 May to 101, with the UK total to 106.
There have been three confirmed cases in Scotland, as well as one in Wales and Northern Ireland.
The first cases of smallpox in Wales and Northern Ireland were recorded on Thursday, while Scotland confirmed two more cases.
