A fast-spreading Ebola epidemic sparked states of emergency in overwhelmed west African nations Thursday as the death toll neared 1,000 and an elderly Spanish missionary flew home for treatment.
In Liberia, where the dead lay in the streets, lawmakers gathered to ratify a state of emergency while Sierra Leone sent troops to guard hospitals and clinics handling Ebola cases. Nigeria held out hope it could receive an experimental US-developed drug to halt the spread of the virus.
Since breaking out earlier this year, the epidemic has claimed 932 lives and infected more than 1,700 people across west Africa, according to the World Health Organisation.
Ebola causes severe fever and, in the worst cases, unstoppable bleeding. It is transmitted through close contact with bodily fluids, and people who live with or care for patients are most at risk.
As African nations struggled with the sheer scale of the epidemic, Spain flew home a 75-year-old Roman Catholic priest, Miguel Pajares, the first patient in the outbreak to be evacuated to Europe for treatment.
A specially equipped military Airbus A310 brought him to Madrid's Torrejon air base along with a Spanish nun, Juliana Bonoha Bohe, who had worked at the same clinic but has not tested positive for the deadly haemorrhagic fever, the Spanish government said.
Immediately after landing Thursday morning, the priest and the nun were taken by ambulance to Madrid's Carlos III Hospital, which specialises in tropical diseases.
- Fight for survival -
Two Americans who worked for Christian aid agencies in Liberia and were infected with Ebola while taking care of patients in Monrovia were taken back to the United States for treatment in recent days.
They have been showing signs of improvement after being given an experimental drug known as ZMapp, which is hard to produce on a large scale and have been showing signs of improvement.
The vast majority of those infected face a far inferior level of health care at home.
There is no proven treatment or cure for Ebola and the use of the experimental drug has sparked controversy as Ebola experts call for it to be made available to African victims.
Liberia President Ellen Johnson Sirleaf declared a state of emergency of at least 90 days on Wednesday, saying extraordinary measures were needed "for the very survival of our state".
"The scope and scale of the epidemic, the virulence and deadliness of the virus now exceed the capacity and statutory responsibility of any one government agency or ministry," she said.
Liberia's parliament is to ratify the decision Thursday.
In Sierra Leone, which has the most confirmed infections, 800 troops including 50 military nurses were sent to guard hospitals and clinics treating Ebola patients, an army spokesman said. The parliament was to meet to ratify a state of emergency declared last week.
- 'Too soon' for new drug? -
Fears are growing that the disease is also taking hold in Nigeria after the death of a nurse in Lagos, a megacity of more than 20 million. It was the second Ebola death in Nigeria, where another five people have tested positive for the disease.
Nigeria's Health Minister Onyebuchi Chukwu told reporters he was in contact with the US Center for Disease Control on the possibility of getting drugs from them.
"I said we are getting reports that this experimental drug seems to be useful. Is it also possible that we can have access for our people presently being treated and under incubation?" he said Wednesday.
Chukwu said all seven confirmed cases in his country had "primary contact" with Patrick Sawyer, a Liberian finance ministry employee who brought the virus to Lagos on July 20 and died later in hospital.
US President Barack Obama said it was too soon to send experimental drugs for the treatment of Ebola to west Africa, however, urging them instead to focus on building a "strong public infrastructure".
"I think we have to let the science guide us. And I don't think all the information is in on whether this drug is helpful," Obama said on Wednesday.
- International crisis -
The World Health Organisation is meeting in emergency session behind closed doors in Geneva to decide whether to declare an international crisis. It is not expected to make a decision until Friday.
The US disease control and prevention body on Wednesday issued its highest alert for an all-hands on deck response to the Ebola crisis in West Africa.
Level 1 is the highest on a 1-6 scale and signals that increased staff and resources will be devoted to the outbreak.
A Saudi Arabian who had travelled to Sierra Leone and developed Ebola-like symptoms died on Wednesday of a heart attack while being treated in hospital in Jeddah, the Saudi health ministry said.
The new global head of the Red Cross, Elhadj As Sy, told AFP that Ebola will be contained only if the public is won over, saying "stigma and discrimination often kill as much as viruses".
First discovered in 1976 and named after a river in what is now the Democratic Republic of Congo, Ebola spreads through contact with bodily fluids such as blood, saliva and sweat.
It has killed around two-thirds of those it has infected over the last four decades, with two outbreaks registering fatality rates approaching 90 per cent. The latest outbreak has a fatality rate of around 55 per cent.
