When working to try to figure out how Ebola was spreading in the Congo, investigators found that patients recently visited a health clinic for treatment for some other disease such as a respiratory infection or malaria, according to an article on the NPR website.
Even government-run facilities such as large hospitals hadn't set up triage tents to separate possible Ebola patients from everyone else.
Even more problematic, are the hundreds of unofficial private health facilities in this area.
These facilities are also often short on supplies and people may be using gloves or the same equipment several times.
