A nurse who is in a "serious condition" with a late complication of the Ebola infection visited a school the day before she was readmitted to hospital.
Pauline Cafferkey was flown from Glasgow to an isolation unit at the Royal Free Hospital in Hampstead, north-west London, in a military aircraft in the early hours of Friday morning, after being admitted to a Scottish hospital on Tuesday.
The London hospital said she is in a "serious condition" in the special unit where she was first treated last December.
It has now emerged that Cafferkey visited Mossneuk Primary School in East Kilbride, South Lanarkshire, on Monday to thank children for their fund-raising efforts, the Press Association reports.
Jim Gilhooly, the council's executive director of education resources, said: "Having returned to work as a nurse some time ago, Pauline gave a presentation at an assembly to pupils in the upper school, P4-P7 . She wanted to thank them for their fund-raising earlier in the year as well as share her experiences as a nurse.
"We have been assured that her illness cannot be spread through ordinary social contact, and we have reassured parents and carers of this. NHS Lanarkshire staff attended the school on Friday to reassure anyone with concerns.
"The school sends Pauline its best wishes and hopes she has a speedy recovery."
The school, which is now closed for the October break, has not received any formal complaints from parents.
Ebola has been shown to persist for weeks or even months in parts of the body and in bodily fluids such as breastmilk, semen and fluid inside the eyeball.
An earlier statement from the Royal Free detailed how the virus can be spread: "The Ebola virus can only be transmitted by direct contact with the blood or bodily fluids of an infected person while they are symptomatic, so the risk to the general public remains low and the NHS has well-established and practised infection control procedures in place."
People who have been in close contact with Cafferkey are being monitored by Scottish health authorities as a precaution.
The 39, who is from South Lanarkshire, was diagnosed with Ebola in December after returning to Glasgow from Sierra Leone via London.
She spent almost a month in an isolation unit at the Royal Free Hospital before being discharged in late January.
A statement from NHS Greater Glasgow and Clyde said Cafferkey was admitted to the infectious diseases unit at Queen Elizabeth University Hospital in Glasgow on Tuesday after feeling unwell.
Director of public health, Dr Emilia Crighton, said: "Pauline's condition is a complication of previous infection with the Ebola virus.
"The risk to the public is very low. In line with normal procedures in cases such as this, we have identified a small number of close contacts of Pauline's that we will be following up as a precaution."
Scotland's First Minister Nicola Sturgeon tweeted: "My very best wishes to Pauline Cafferkey for a speedy recovery."
Heath Secretary Jeremy Hunt also tweeted his best wishes, saying: "Thoughts with Pauline Cafferkey today as she battles Ebola for the second time.
"In best poss place under care of Dr Mike Jacobs at Royal Free."
Scotland's Chief Medical Officer, Catherine Calderwood, said everyone worked to ensure Ms Cafferkey had received all appropriate treatment and care prior to and during her transfer to the Royal Free.
She added: "Pauline is now being cared for in the best place possible, with specialists who have the most experience of looking after patients who have previously recovered from the Ebola virus."
Cafferkey contracted Ebola while working as a nurse at the Save the Children treatment centre in Kerry Town.
A report from the charity in February said she was probably infected as a result of using a visor to protect her face rather than the standard protective goggles because she could not get them to fit properly.
Cafferkey's temperature was tested seven times before she flew from Heathrow to Glasgow in December, and she had been cleared for travel.
She was placed in an isolation unit at Glasgow's Gartnavel Hospital after becoming feverish, before being transferred by an RAF Hercules plane to London on December 30.
She was then transferred to the specialist isolation unit at the Royal Free.
Cafferkey won an award at the the Pride of Britain Awards in central London on September 28.
She met the Prime Minister's wife Samantha Cameron the following day at Downing Street, alongside other winners.
The most recent outbreak of Ebola mainly affected three countries in West Africa: Guinea, Liberia and Sierra Leone.
More than 28,000 cases and more than 11,000 deaths have been reported by the World Health Organisation.
Dr Ben Neuman, lecturer in virology at the University of Reading, said he thought Cafferkey's case was only the second one where Ebola is reported to have "reactivated".
