Six people are currently in isolation at the hospital, including Mrs Romero Ramos and her husband.

Two doctors who treated her have been admitted for precautionary observation, while two nurses who worked alongside Mrs Romero Ramos are also in quarantine.

One of the doctors has complained that the sleeves on his protective suit were too short.

It emerged today two hairdressers are being monitored for the symptoms after they came into contact with Mrs Romero Ramos after she saw her doctor.

A spokeswoman for the Carlos III hospital said neither of the doctors, nor the nurse's husband, has shown any symptoms of the deadly virus.

The two nurses currently in quarantine are awaiting tests to reveal if they have the disease.

Mrs Romero Ramos is the first person known to have caught the disease outside the outbreak zone in West Africa.

So far the epidemic, the worst on record since Ebola was discovered in 1976, has claimed 3,800 lives and infected at least 8,000 people.

Mrs Romero Ramos, from Galicia in north-west Spain, was one of the medical team that treated two repatriated Spanish priests, Miguel Pajares and Manuel Garcia Viejo, who died from Ebola.

Health officials said she twice entered the room of Spanish missionary Manual Garcia Viejo - once to clean him and the second time to tidy up after he died on September 25, just days after he was repatriated from Sierra Leone.

Doctor German Ramirez of the Carlos III hospital said Mrs Romero Ramos told him she had touched her face with her gloves as she removed her protective suit after leaving the quarantine room where the missionary was being treated.

'It seems like it was the gloves. The gloves touched the face,' he said.

'It is possible that this was not a mistake as such. It could simply be an accident and logically, probably, she could not remember at the beginning because of the state of her health.'

Romero herself said in an interview Wednesday in the online edition of El Pais newspaper that the point when she removed her protective suit was 'the most critical moment in which it could have happened, but I am not sure'.

The Madrid regional health minister Javier Rodriguez said he thought the infection had been due to a 'mistake' on the part of the nurse or an 'accident'.

'She has said herself that she probably made a mistake,' he said.

'That reassures us because the safety protocol were observed correctly. If a mistake was made, we will have to find out why,' he told reporters.

'We are not trying to blame her,' he added. 'I think it was an accident on the part of the patient.'

Mr Rodriguez earlier told regional lawmakers in a hearing that Mrs Romero Ramos had visited her family doctor shortly after feeling ill on September 29 and 'concealed from the doctor the fact that she was a nurse who had been in direct contact with a patient infected with Ebola'.

She then called a medical helpline for hospital staff on October 2 and told them she had a fever, but was not admitted to hospital until October 6.

She has been held in quarantine since she was diagnosed with the virus.

The nurse has now admitted touching her face with her gloves as she took off a protective suit after leaving the room of one of the priests.

Nobody ever told me to my face, "Teresa you’ve got ebola" Teresa Romero Ramos

Mrs Romero Ramos confessed her accident to a doctor after earlier insisting that she had no idea how she became infected.

Hospital chief German Ramirez said yesterday – 48 hours after the launch of a probe into how Mrs Romero Ramos caught the virus – 'It looks like we have found the origin.'

But the speed with which he attributed the shock transmission to a 'slip-up' failed to silence critics who demanded that heads rolls after a string of spectacular mistakes by health co-ordinators.

Health minister Ana Mato is facing calls for her resignation after it emerged that Mrs Romero Ramos complained of feeling unwell six days before she was eventually admitted to hospital.

She was rushed to hospital by unprotected paramedics in a normal ambulance only taken out of service 12 hours later and found out she had Ebola by reading a Spanish newspaper website as she waited to be quarantined.

Her home in Alcorcon near Madrid that she shares with husband Javier Limon Romero, one of those quarantined at Madrid's Carlos III Hospital, was not disinfected until yesterday morning.

Mrs Romero Ramos was reportedly feeling better after being treated with antibodies from an Ebola survivor.

She told a Spanish TV station by phone, yesterday: 'Today I'm better. It's slow going but I'm better.'

Revealing how she discovered she was infected, she said: 'Nobody told me anything.

'I suspected something because at the beginning the nurses and doctors came in every hour, then they stopped coming in and I thought that something was up.

'I got hold of my mobile and that's when I saw on the website of El Pais newspaper that I had tested positive for Ebola twice. Nobody ever told me to my face, 'Teresa you've got ebola'.'

She went on to say that she had been given only 20 minutes' training in how to put on and take off her protective suit.

On Thursday another doctor, who cared for Romero and is among those now in isolation, said the sleeves on the protective suit he wore while handling her had been too short.

In a letter to healthcare authorities, published by national newspaper El Pais, the doctor detailed treating Romero during a gruelling 16-hour shift during which he was not told she had the Ebola virus. He said he only learned of this via the press.

News Romero's condition had deteriorated came the day after the authorities put her pet dog down amid fears he could transmit the disease.

Fury erupted after a government health spokesman confirmed Excalibur had been destroyed.

The official explained: 'Unfortunately we had no other choice.'

The animal was put to sleep inside Mrs Romero Ramo's home, which was disinfected before the animal's body was taken away in a white van to a nearby incinerator.

Demonstrators who mounted a vigil outside to try to stop the move shouted 'murderers' and several threw themselves on the ground as the vehicle left.

Some 300,000 people signed a petition urging authorities to spare Excalibur.

Twitter was awash with photographs of dogs, cats and birds which were posted alongside the hashtag 'SalvemosAExcalibur' – Spanish for 'Let's save Excalibur'.

In Australia a volunteer nurse who travelled to Sierra Leone to help battle Ebola is feared to have caught the disease.

Sue Ellen Kovack, 57, is being monitored inside a Queensland hospital and is said to be 'in good spirits', a Red Cross Australia spokesman said.

In the U.S an extra level of screening at major airports will reach more than 9 of 10 people traveling there from Ebola-ravaged countries in West Africa, the White House announced, on the same day that the first person to be diagnosed with Ebola in America died.

About 150 travelers a day will have their temperatures checked using no-touch thermometers. Health officials expect false alarms from fevers due to malaria.

The extra screening likely wouldn't have singled out Thomas Eric Duncan when he arrived from hard-hit Liberia last month, because he had no symptoms while traveling. Duncan died on Wednesday in Dallas.

A Dallas sheriff who entered Duncan's apartment is being monitored for Ebola as a precaution.

Sgt Michael Monnig reportedly woke up feeling nauseous after spending about half an hour in the property.

Meanwhile, a medical official with the U.N. Mission in Liberia who tested positive for Ebola arrived in the German city of Leipzig to be treated at a local clinic with specialist facilities, authorities said.

The unidentified medic infected in Liberia is the second member of the U.N. mission, known as UNMIL, to contract the virus. The first died on September. 25. He is the third Ebola patient to arrive in Germany for treatment.
