The World Health Organization says vaccinations could begin as early as Wednesday in Democratic Republic of Congo since the Zaire strain of the deadly virus has been confirmed.

Three more cases of the deadly Ebola virus have been confirmed in Democratic Republic of Congo's (or DRC) latest outbreak, the country's health ministry said on Tuesday, while the World Health Organization (WHO) said vaccinations could begin as early as Wednesday.

The outbreak declared last week in North Kivu province in the northeast near Uganda and Rwanda is a new outbreak and not connected to the one in DRC's northwest that was declared over on July 24, WHO's emergency preparedness chief Peter Salama said on Twitter.

Difficult to deal with outbreak

He cited new results of genetic analysis that confirm the strain of Ebola in the new outbreak is the Zaire strain, one for which the vaccine can be used.

DRC's health ministry has said the new vaccination campaign will target health care providers, contacts of confirmed Ebola cases and their contacts, the same strategy that was used to contain the previous outbreak in Equateur province in which more than 3,300 people were vaccinated. 

That outbreak more than 2,500 kilometres away had 33 confirmed Ebola deaths.

Tarik Jasarevic from the WHO explains why it is so difficult to deal with the latest outbreak.

War adds to challenge

WHO has said 3,000 doses of the vaccine are still in DRC's capital, Kinshasa, and that it can access up to 300,000 more on short notice.

Health experts in the city closest to the new outbreak, Beni, have been setting up "cold chains" to keep the vaccines at the optimal temperature of minus 70 degrees Celsius, a challenge in a region with hot temperatures and unreliable power supplies.

WHO has warned that this new outbreak poses a particular challenge as the region is a "war zone" with several active armed groups and tens of thousands of displaced people. 

Heavily traveled borders nearby with Uganda and Rwanda also complicate efforts to contain the disease, which is spread via contact with the bodily fluids of those infected, including the dead.

New deaths confirmed

At least four Ebola deaths are confirmed in the new outbreak, Health Minister Dr Oly Ilunga Kalenga said in a statement. 

There are now 16 confirmed cases of the hemorrhagic fever, 27 probable cases and 31 suspected ones under investigation.

Health experts have identified at least 966 contacts who are now under surveillance.

The central African country has dealt with Ebola for decades and this is its tenth outbreak of the virus. Ebola, first identified in the country in 1976, jumps to humans from animals including bats and monkeys.

There is no specific treatment, and the virus can be fatal in up to 90 percent of cases, depending on the strain.
