Health officials have warned that containing the outbreak in North Kivu province is complicated by the presence of multiple armed groups vying for mineral-rich land in the northeastern region that borders Uganda and Rwanda.
The latest outbreak, declared Aug. 1 in Mangina village in the Mabalako health zone, is Congo's tenth outbreak since the virus was identified in 1976.
This outbreak has seen 16 confirmed Ebola cases, 27 probable cases and 46 suspected ones.
Three thousand doses of the Ebola vaccine are being sent from Kinshasa, the capital, and will be used first in the Mabalako health zone and in the nearby city of Beni, which has more than 680,000 people.
The experimental vaccine was used in an earlier, unrelated outbreak in Congo's northwest that was declared over last month.
The first to be vaccinated are health workers, contacts of confirmed Ebola cases and their contacts in what is called a ring vaccination campaign.
The strategy is the same that was used to contain the previous outbreak in Equateur province, with more than 3,300 people vaccinated.
"I will be very content to receive the vaccination tomorrow," said Solange Mbambu. "When I see the doctors preparing the funerals for those who have died from Ebola, without their family, it gives me goose bumps."
Ebola jumps to humans from animals including bats and monkeys. It can be spread through contact of bodily fluids of someone infected, living or dead. There is no specific treatment, and the virus can be fatal in up to 90 percent of cases, depending on the strain.
Genetic analysis has confirmed the virus strain in this latest outbreak is the Zaire one.
