AZUZ: Medical teams are rushing to contain an outbreak of the Ebola virus in Central Africa. Two cases have been confirmed in the northwestern part of the Democratic Republic of Congo. But over the past five weeks, there have been 21 suspected cases of Ebola and 17 people have died from it.

On average, the hemorrhagic fever kills about 50 percent of the people who catch it. Scientists don't know exactly where Ebola comes from. They believe it's transmitted to people from wild animals and then spread from person to person.

Government officials and international medical workers, including some with the World Health Organization are all trying to work together to stop Ebola spread in the Democratic Republic of Congo. Still, a Congolese official says there's a, quote, worrisome sanitary situation related to this outbreak.

Ebola is a rare disease, but it is native to the DRC. This is the ninth time there's been an outbreak there. That virus and others like it have welled up in several countries throughout Central and West Africa, the worst being an Ebola outbreak in March of 2014, which sickened more than 28,000 people, mostly in Guinea, Liberia and Sierra Leone.

There is no cure or approved vaccine for Ebola. Chances of survival can be improved with intravenous fluids, oxygen and medical monitoring.
