The number of people killed by the contagious virus for which there is no known treatment has now risen to 31, including five health workers. Ebola causes massive bleeding and kills up to 90 percent of its victims.
“The epidemic is not under control. On the contrary the situation is very, very serious,” Eugene Kabambi, a WHO spokesman in Congo’s capital Kinshasa, told Reuters by phone.
“If nothing is done now, the disease will reach other places, and even major towns will be threatened,” he said, adding that an estimated $2 million had to be urgently found to pay for measures to tackle the disease.
The outbreak, which is believed to have been caused by tainted bushmeat hunted by local villagers, has so far struck in the towns of Isiro and Viadana in the northeastern province of Orientale.
Some 16 people in neighboring Uganda died of the disease last month, though the WHO said the two epidemics were not connected.
The latest WHO figures show there are now 65 probable or suspected cases of Ebola in Congo, with 108 people under surveillance.
