At least 826 people have died in West Africa from the Ebola virus.
Even though the number is expected to rise, it's still more deaths than any previous outbreak of the deadly disease.
And that ironically, may be why there's no vaccine or treatment available.
"Prior episodes burned themselves out with fewer deaths after a shorter time," said Dr. Aileen Marty, an infectious disease professor at Florida International University.
"That's meant less of a feeling that a vaccine should be on the market," she explained. "There's no money in it. But it's such a horrible way to die."
Experts say there are Ebola treatments and vaccines in various testing stages at several U.S. research centers, mostly funded by the government. Most of the drugs have been tested so far mostly on animals, with no target date for availability.
There are a few small American companies developing treatments, such as BioCryst and NancoViricides, One Canadian firm, Tekmira, is also working on a treatment, with funds from the U.S Defense Department. Larger outfits have shied away.
"It's tough to develop these drugs because they might not even be used," said Dr. Chris Milne, director of research at the Tufts Center for the Study of Drug Development.
Milne said that pharmaceutical companies can spend millions in developing flu vaccines that get thrown away because they're ineffective on new virus strains.
"It's a lot of time, effort and money to develop something like an Ebola vaccine with little guarantee of a profit," he said.
