All UK-based passengers and crew aboard two flights taken by a Scottish nurse who contracted Ebola in Sierra Leone have now been contacted by medical authorities, Public Health England (PHE) said.

Pauline Cafferkey, a public health nurse who had been volunteering in the stricken West African country, is receiving specialist treatment at the Royal Free Hospital in north London.

She was diagnosed with the deadly virus after returning to Glasgow from Heathrow, after flying to the UK from Sierra Leone via Casablanca in Morocco.

PHE said passengers and crew members on the flights to Heathrow and Glasgow on Sunday have now been contacted.

Speaking about the British Airways flight from Heathrow to Glasgow, a PHE spokeswoman said: "All 71 passengers and all crew members on this flight have been contacted as of 1st January 2015, given advice and reassurance by officials from Health Protection Scotland."

Of the Royal Air Maroc flight from Casablanca to Heathrow, she said: "All 101 UK-based passengers and all crew members on this flight have been contacted, given advice and reassurance by officials from Public Health England as of 2nd January 2015.

"The additional 31 international passengers on this flight are being contacted by international public health authorities."

The Moroccan Ministry of Health has also been tracing passengers aboard the Royal Air Maroc flight from Freetown in Sierra Leone to Casablanca as a precautionary measure. All passengers on that flight were screened before they left Freetown and cleared to travel, as well as on their arrival in Casablanca, PHE said.

Dr Michael Jacobs said Mrs Cafferkey is being treated via a quarantine tent at the Royal Free Hospital with convalescent plasma taken from the blood of a recovered patient and an experimental anti-viral drug which is "not proven to work".

But he revealed the hospital was unable to obtain ZMapp, the drug used to treat fellow British volunteer nurse William Pooley, who recovered, because "there is none in the world at the moment".

Family members are unable to touch her but can see and speak to her through an internal communication system.

Dr Jacobs said there were several stocks of plasma around Europe which would be considered in the treatment of Ms Cafferkey.

"When the need arises, the various experts around Europe convene a conference, and decide the most appropriate plasma for the patient," he said. "It's plasma from a patient who has survived from Ebola and is treated in Europe."

Ms Cafferkey, from Glasgow, was part of a 30-strong team of medical volunteers deployed to Africa by the UK Government last month and had been working with Save the Children at the Ebola Treatment Centre in Kerry Town, Sierra Leone.

She was initially placed in isolation at a Glasgow hospital early on Monday after feeling feverish, before being transferred south on an RAF C-130 Hercules plane.

The healthcare worker had flown from Sierra Leone via Morocco to Heathrow, where she was considered a high risk because of the nature of her work but showed no symptoms during screening and a temperature check.

However, while waiting for a connecting flight to Glasgow she raised fears about her temperature and was tested a further six times in the space of 30 minutes.

Despite her concerns, she was given the all-clear and flew on to Scotland where, after taking a taxi home, she later developed a fever and raised the alarm.

The Government's chief medical officer, Dame Sally Davies, admitted questions have been raised about the airport screening procedure for Ebola but insisted that the nurse's temperature was checked.

The Department of Health said screening processes were followed, but that protocols would be reviewed.

Further volunteers from the UK are expected to be trained and deployed in the coming weeks, the Department for International Development has said.
