Ebola Said to Be Source of Mysterious, Deadly Epidemic

Guinea identified the Ebola virus Saturday as the source of a highly contagious epidemic raging through its southern forests, as the death toll rose to 59.

Experts in the west African nation had been unable to identify the disease, whose symptoms -- diarrhea, vomiting and bleeding -- were first observed six weeks ago, but scientists studying samples in the French city of Lyon confirmed it was Ebola, the Guinean health ministry said.

"The Ebola fever epidemic raging in southern Guinea, including the prefectures of Gueckedou and Macenta, since February 9 has left at least 59 dead out of 80 cases identified by our services on the ground," said Sakoba Keita, the ministry's chief disease prevention officer.

"We are overwhelmed in the field, we are fighting against this epidemic with all the means we have at out disposal with the help of our partners but it is difficult. But we will get there," he said.

To date, no treatment or vaccine is available for Ebola, which kills between 25 and 90 percent of those who fall sick, depending on the strain of the virus, according to the World Health Organization.

The disease is transmitted by direct contact with blood, feces or sweat, or by sexual contact or unprotected handling of contaminated corpses.

Medical aid group Doctors Without Borders (MSF) said in a statement it would strengthen its team of 24 doctors, nurses, logisticians and experts in hygiene and sanitation already in Guinea.

The organization has set up isolation units for suspected cases in the southern region of Nzerekore and is looking for people who may have had contact with the infected.

"These structures are essential to prevent the spread of the disease, which is highly contagious," said MSF tropical medicine adviser Esther Sterk said.

"Specialized staff are providing care to patients showing signs of infection."

MSF said it was sending around 33 tonnes of medicines and isolation, sanitation and protective equipment in two planes leaving from Belgium and France.

Ebola, one of the world's most virulent diseases, was first discovered in the Democratic Republic of Congo (DRC) in 1976 and the country has had eight outbreaks.

The most recent epidemic, in the DRC, infected 62 people and left 34 dead between May and November 2012, according to the country's health ministry.

There are fears it could be used in a biological weapons attack.

According to researchers, the virus multiplies quickly, overwhelming the immune system's ability to fight the infection.

The French embassy in the Liberian capital Monrovia released a travel advisory warning French citizens against travel to the affected parts of Guinea or areas of northern Liberia near the border between the countries.
