Nurse Pauline Cafferkey, who survived the deadly Ebola virus, has given birth to twin sons.
Ms Cafferkey, 43, from South Lanarkshire, Scotland, hailed their arrival as proof that "there is life after Ebola".
The Scottish nurse spent two years battling the deadly virus, having contracted it in 2014 while doing aid work in Sierra Leone.
The proud father Robert Softley Gale, a theatre director and disability campaigner, announced the news by posting a photo of the newborns on Instagram.
The boys were born on Tuesday in Glasgow and have yet to be named, the BBC has reported.
Paying tribute to the NHS staff who have helped her over the years, Ms Cafferkey said: "I would like to thank all the wonderful NHS staff who have helped me since I became ill in 2014 right through to having my babies this week.
"This shows that there is life after Ebola and there is a future for those who have encountered this disease."
A spokeswoman for NHS Greater Glasgow and Clyde said both the mother and babies were "doing well".
Ms Cafferky first went to Sierra Leone during the West African Ebola epidemic, which killed more than 11,000 people between 2013 and 2016.
After working on behalf of charity Save the Children, she returned to the UK where she was struck down with the disease.
The nurse spent a month in an isolation unit at a hospital in London before doctors discharged her.
But she was then readmitted to hospital three times – in October 2015, February 2016 and October the same year – after suffering complications linked to the disease.
It comes as the virus once again grips the African continent, showing “no sign of stopping” in the Democratic Republic of Congo.
Nearly 1,400 people have died in the central African country since the fresh Ebola epidemic broke out in August 2018, with the disease now spreading to Uganda.
A five-year-old boy infected with the virus died on Tuesday and his 50-year-old grandmother died on Wednesday, the Ugandan health ministry has said, with at least six other cases of the reported over recent days.
The World Health Organisation is expected to declare an international emergency over the epidemic in the coming days
Dr Jeremy Farrar, the director of the Wellcome Trust, said the epidemic was the worst since that of 2013-16 and has showed "no sign of stopping".
In a statement, Dr Farrar said the spread was "tragic but unfortunately not surprising".
He warned that more cases were expected, and a "full" national and international response would be needed to protect lives.
