How much do you know about the current Ebola virus outbreak?

Updated

The most severe Ebola outbreak of our time began in Guinea in March and has since spread to multiple West African countries. As of Oct. 2, more than 6,500 probable, confirmed and suspected cases have been reported, and more than 3,000 patients have died. According to the Centers for Disease Control and Prevention (CDC), for every one reported case of Ebola, there are an additional 1.5 that go unlisted. If these trends continue, the CDC estimates that cases in two countries alone – Liberia and Sierra Leone – could reach 1.4 million within four months.

On Sept. 30, the CDC confirmed the first diagnosis of Ebola in the United States. Eric Duncan, 42, began exhibiting symptoms of the disease on Sept. 24, four days after returning to the United States from Africa. On Oct. 8, Eric Duncan died from the disease. 

On Sunday, health officials confirmed that a nurse at the Texas Health Presbyterian Hospital in Dallas tested positive for Ebola after caring for Duncan. The case marks the first person-to-person transmission of Ebola in the U.S.
