The World Health Organisation on Friday declared the killer Ebola epidemic ravaging parts of west Africa an international health emergency and appealed for global aid to help afflicted countries.
The decision after a two-day emergency session behind closed doors in Geneva means global travel restrictions may be put in place to halt its spread as the overall death toll nears 1,000.
The WHO move comes as US health authorities admitted on Thursday that Ebolaโs spread beyond west Africa was โinevitableโ, and after medical charity Doctors Without Borders (MSF) warned that the deadly virus was now โout of controlโ with more than 60 outbreak hotspots.
WHO director Dr Margaret Chan appealed for greater international aid for the countries worst hit by the outbreak, which she described as the most serious in four decades, echoing an earlier claim by MSF that the โepidemic is unprecedented in terms of geographical distribution, people infected and deathsโ.
States of emergency were in effect across overwhelmed west African nations, including Libera, Guinea and Sierra Leone.
Soldiers in Liberiaโs Grand Cape Mount province โ
one of the worst-affected areas โ set up road blocks to limit travel to the capital Monrovia, as bodies reportedly lay unburied in the cityโs streets.
Two towns in the east of Sierra Leone, Kailahun and Kenema, where put under quarantine on Thursday, as nightclubs and entertainment venues across the country were ordered shut.
Public sector doctors in Nigeria suspended a month-long strike with fears rising that the virus is taking hold in sub-Saharan Africaโs most populous country. The deadly tropical disease has already killed two and infected five others in Lagos.
Ebola has claimed at least 932 lives and infected more than 1,700 people since breaking out in Guinea earlier this year, according to the WHO.
– โAfricans should get new drugโ –
As African nations struggled with the scale of the epidemic, the scientists who discovered the virus in 1976 have called for an experimental drug being used on two infected Americans to also be made available for African victims.
One of the three, Peter Piot, director of the London School of Hygiene and Tropical Medicine, said โAfrican countries should have the same opportunityโ to use ZMapp, which is made by US company Mapp Pharmaceuticals.
Ebola causes severe fever and, in the worst cases, unstoppable bleeding. It is transmitted through contact with bodily fluids, and people who live with or care for patients are most at risk.
Spain flew home a 75-year-old Roman Catholic priest, Miguel Pajares, the first European victim of the epidemic, on Thursday. Officials said his condition was stable.
– Families separated –
In Liberia, President Ellen Johnson Sirleaf said people should expect certain rights to be suspended as the country imposes โextraordinary measuresโ necessary for โthe very survival of our stateโ.
In Sierra Leone, which has the most confirmed infections, 800 troops were sent to guard hospitals treating Ebola patients, an army spokesman said.
The outbreak in Nigeria has been minor compared to those in Guinea, Liberia and Sierra Leone.
The densely-packed city of more than 20 million people has a poor healthcare system and officials say that if Lagos sees a rise in infections, public hospitals will need to be operational in order to avert a catastrophe.
Benin said it had placed two patients with Ebola-like symptoms in isolation and was waiting for test results to establish if the pair were infected.
– Americans โimprovingโ –
The two infected Americans, who worked for Christian aid agencies in Liberia, have shown signs of improvement since being flown to a specialist hospital in Atlanta, Georgia. They are being given ZMapp, according to reports.
There is no proven treatment or cure for Ebola and the use of the experimental drug has sparked an ethical debate.
US President Barack Obama said it was too soon to send the experimental drugs to west Africa.
โI think we have to let the science guide us. And I donโt think all the information is in on whether this drug is helpful,โ he said Wednesday.
Nigeriaโs Health Minister Onyebuchi Chukwu has asked the US about getting the drug, but Spain has voiced caution about the serum.
US regulators meanwhile loosened restrictions on another experimental drug which may allow it to be tried on infected patients in west Africa.
Canada-based Tekmira said the US Food and Drug Administration changed the classification of its drug TKM-Ebola from full clinical hold to partial hold.
US health authorities also warned Ebolaโs spread to the United States was โinevitableโ due to the nature of global airline travel, but that any outbreak was not likely to be large.
The worsening outbreak prompted the United States to order the families of embassy staff in Liberia to return home, with the State Department also warning US citizens not to travel to Liberia.
First discovered in 1976 and named after a river in what is now the Democratic Republic of Congo, Ebola has killed around two-thirds of those infected, with two outbreaks registering fatality rates approaching 90 percent. The latest outbreak has a fatality rate of around 55 percent.
