An Ebola survivor says the hospital in Liberia where American aid workers got sick with Ebola doesn't have enough hazard suits and other supplies to keep doctors and nurses safe, according to an article on the NOLA.com website.

About 250 staffers at the hospital use thousands of disposable protective suits each week, but that's not enough to fully protect the doctors and nurses who must screen people entering the emergency room or treat patients outside the 50-bed Ebola isolation unit, Nancy Writebol said.

"We don't have enough personal protective safety equipment to adequately be able to safely diagnose if a patient has Ebola. So they are putting themselves at risk," Writebol's husband, David, said in the article.

The disease is spreading faster than the response for lack of protective gear and caregivers, said Tom Kenyon of the U.S. Centers for Disease Control and Prevention. At least $600 million is urgently needed to provide these tools and extra hazard pay so that more doctors and nurses are willing to risk their lives, the World Health Organization said.

Healthcare workers at other West African hospitals have gone on strike demanding more protections, the Writebols said.

Any fully-equipped hospital that follows safety protocols could prevent an American outbreak while caring for an Ebola patient, the article said. But there are four high-level isolation units designed especially to handle infectious diseases.
