According to Reuters, the world's worst outbreak of Ebola that has killed nearly 1,000 people in West Africa represents an international health emergency and could continue spreading for months, the World Health Organization (WHO) said on Friday (August 8).
Nigeria became the third African nation, after Sierra Leone and Liberia, to declare a national emergency on Friday as the region's healthcare systems struggle to cope with the advance of one of the deadliest diseases known to man.
"The outbreak is moving faster than we can control it," WHO Director-General Margaret Chan told reporters on a telephone briefing from her Geneva headquarters.
The UN agency said all states where Ebola had passed from one person to another should declare a national emergency. It called the outbreak "particularly serious" but said there should be no general ban on international travel or trade.
"The declaration...will galvanize the attention of leaders of all countries at the top level. It cannot be done by the ministries of health alone," Chan said.
In Nigeria, which has confirmed seven cases of Ebola since a man fell sick on arrival from Liberia, President Goodluck Jonathan declared a national state of emergency and approved 1.9 billion naira ($11.7 million) of emergency funds to combat the virus.
WHO has been accused of failing to respond fast enough to the outbreak, which it said on May 18 could be declared over by May 22. It has since become more conservative in its predictions, said head of health security, Keiji Fukuda.
"The likelihood is that things will get worse before they get better," he said, adding that the WHO is prepared for an outbreak that persists at a high level for months.
COMMENT: Medecins Sans Frontieres (MSF) said the declaration showed WHO's seriousness in tackling the outbreak, but added that statements should be translated into action.
"For weeks, MSF has been repeating that a massive medical, epidemiological and public health response is desperately needed to save lives," said MSF Director of Operations Bart Janssens.
Ebola has no proven cure and there is no vaccine to prevent infection, so the best treatment is focussed on alleviating symptoms that include fever, vomiting and diarrhea.
Its spread could be stopped with the right measures to deal with infected people, Fukuda said, but it was important that anyone known to have Ebola should be immediately isolated and treated in isolation for 30 days.
The US Agency for International Development said on Friday its officials had announced more than $12 million in additional funding this week to help curb the outbreak.
The European Union said on Friday it was increasing by 8 million euros ($10.7 million) its funding to contain Ebola and governments in the affected region have taken increasingly tough measures.
In one example, about 30 military officers armed with AK-47s guarded a checkpoint blocking a line of trucks laden with goods from traveling from Montserrado County to the rest of Liberia.
The latest WHO figures on Friday showed the worsening toll. Some 1,779 people have been infected and 961 people have died in the most severe outbreak in the 40 years since it was first identified in humans.
This was partly because of weaknesses in the countries affected, where health systems are fragile and lacking in resources. Sierra Leone has one local doctor for roughly 45,588 people while Liberia has one for every 86,275 people, according to political risk research company DaMina Advisors.
Although most cases of Ebola are in the remote area where Guinea borders Sierra Leone and Liberia, alarm over the spread of the disease increased last month when a US citizen died in Nigeria after traveling there by plane from Liberia.
The US State Department has ordered the departure of family members from its embassy in the Liberian capital Monrovia and said it was acting "out of an abundance of caution."
Airline Gambia Bird said it was now only offering one-way flights from the Gambian capital Banjul to Ebola-affected countries, following a request from the government.
After an experimental drug was administered to two US charity workers who were infected in Liberia, Ebola specialists have urged the WHO to offer such drugs to Africans. The UN agency has asked medical ethics experts to explore this option next week.
