Monrovia (AFP) - Liberian President Ellen Johnson Sirleaf has announced the closure of most of the Ebola-hit country's land borders after the deadly tropical virus spread to two of west Africa's largest cities.
Liberia, along with neighbouring Guinea and Sierra Leone, is struggling to contain an epidemic that has infected some 1,200 people and left at least 670 dead across the region since the start of the year.
Last week authorities in Sierra Leone's capital Freetown and Lagos in Nigeria announced their first cases, marking an alarming new front in the fight against a disease mainly confined to remote villages and rural outposts.
"All borders of Liberia will be closed with the exception of major entry points," Sirleaf said in a statement late Sunday.
Monrovia's international airport, a provincial airport and three major crossings were exempted from the closures.
"At these entry points, preventive and testing centres will be established," she said.
Liberia has seen 129 deaths from Ebola, which causes severe fever and muscle pain, vomiting, diarrhoea and, in the worst cases, organ failure and unstoppable bleeding.
"A new travel policy by the Liberia Airport Authority covering inspection and testing of all outgoing and incoming passengers will be strictly observed," Sirleaf said in the statement.
The government also banned public gatherings of any kind, including events and demonstrations, and announced quarantines of Ebola-hit communities.
Ebola, which first emerged in 1976, is believed to be carried by animals hunted for meat, notably bats.
It spreads among humans via bodily fluids and has killed 56 percent of those it has infected in the current outbreak.
- 'Jittery over Ebola' -
A 32-year-old trainee hairdresser, the first confirmed case of Ebola in Freetown, died on Saturday after her parents forcibly took her from hospital, according to the health ministry.
Saudatu Koroma's house in the east of Freetown has been quarantined with the other residents for 21 days but Sierra Leoneans across the city voiced fears that the virus may already have spread.
"People are now extremely cautious of how they attend parties and other social functions, although funerals are still largely being attended," social analyst Ronald Cole told AFP.
People in the streets had stopped shaking hands, an AFP correspondent in Freetown said, preferring to proffer elbows as a greeting.
"We should now be bowing like the Chinese," said civil rights activist Ronnie Charles.
Social groups cancelled public events to celebrate the end of the Islamic holy month of Ramadan while restaurants installed buckets of bleached water for customers to wash their hands before taking their seats.
The dead are also being handled with care.
"We are jittery over Ebola. We have given lots of gloves to our workers as a protection to handle corpses," said the owner of a downtown funeral parlour.
Regular public health messages blared out from radios and television sets instructing people how to guard against infection.
Meanwhile the health ministry of Sierra Leone, which has seen 224 deaths from Ebola, announced it had set up an "emergency operation centre" in the capital, coordinated by the World Health Organisation (WHO).
- Flights cancelled -
Freetown's first Ebola case comes after the virus was confirmed to have reached Nigeria's financial capital Lagos, a regional and international transport hub and a base for many foreign multinationals with offices in Africa's largest economy.
A 40-year-old Liberian man died at a private clinic from the disease, after collapsing at Lagos international airport, the Nigerian health ministry said Friday.
With a historic death rate of 67 percent before the current outbreak and no vaccine, patients believed to have caught the Ebola virus must be isolated to prevent further contagion, according to the WHO.
The agency urged people showing the first signs of the virus to go immediately to health centres.
"We must stop the message that there is no treatment. The faster patients seek treatment in secure health centres, the more likely they are to recover and avoid contaminating family members," said spokesman Tarik Jasarevic.
"The WHO strategy is to attack the epidemic at its source, to find people who are sick in the villages, and take care of them in the isolation units," he added.
Jasarevic said "safe burial" of bodies was an important part of the response to the epidemic, adding that family members were touching the body during funeral rituals and getting infected.
