The U.S. experience with Ebola is generating commentary that is both prudent and outrageous.
There have been only three cases of Ebola occurring on U.S. soil, one ending fatally and the other two now under treatment.
While health officials provide sober guidance on the deadly disease, several public figures, from high-level politicians to cultural icons, haven't been so even-tempered in their remarks, adding to the public hype that has become associated with the virus.
Here is a sampling of those provocative comments, plus a little myth busting, clarifying and reality checking from Ebola experts from around the world.
"If you bring two doctors who happen to have that specialty (Ebola) into a room, one will say, 'No, it will never become airborne, but it could mutate so it would be harder to discover.' Another doctor will say, 'If it continues to mutate at the rate it's mutating, and we go from 20,000 infected to 100,000, the population might allow it to mutate and become airborne, and then it will be a serious problem.' I don't know who is right." -- Martin Dempsey, the chairman of the Joint Chiefs of Staff, told CNN.
Dempsey: 'We know so little' about Ebola
Ebola isn't transmitted through the air. It is transmitted through direct contact by bodily fluids with an Ebola-infected person showing symptoms of the disease.
A mutation such as the kind Dempsey describes "would be exceedingly rare" in one epidemic, said Edward C. Holmes of Marie Bashir Institute for Infectious Diseases and Biosecurity at the University of Sydney.
"It happens over evolutionary time, millions of years," Holmes said. "This idea that it takes one or two of those mutations and 'Wham!' you pick up airborne transmission, that is way too simplistic."
"If someone has Ebola at a cocktail party, they're contagious and you can catch it from them. -- Sen. Rand Paul, a physician and potential 2016 presidential candidate
Rand Paul: Ebola is not like AIDS
Again, experts say the contact with an infectious person must be tactile, or direct touching, and involve bodily fluids -- blood, sweat, feces, vomit, semen or spit.
People in West Africa are avoiding hugs and handshakes because the virus can be spread through the sweat on someone's hand.
The uninfected person would have to have a break in the skin of their hand that would allow entry of the virus, CNN's Dr. Sanjay Gupta said. But "we all have minor breaks in our skin. And there is a possibility that some of the virus can be transmitted that way."
Paul also made other remarks regarding direct contact: "They say all it takes is direct contact to get this. If you listen carefully, they say being three feet from someone is direct contact. That's not what most Americans think is direct contact."
Without directly addressing Paul's claims about contact over three feet, Centers for Disease Control and Prevention Director Dr. Thomas Frieden indicated that's not a possible mode of transmission for the virus.
"Should you be worried you might have gotten it by sitting next to someone?" Frieden said, according to the Louisville Courier-Journal. "The answer to that is no."
"The most comforting thing that I heard from (Dr. Brenda Fitzgerald, commissioner of the Georgia Department of Public Health) was that water kills the Ebola virus. I've never heard that before. I thought it was something that was so contagious there wasn't much you could do to prevent it or anything else, so her advice was 'wash your hands.' " -- Georgia Gov. Nathan Deal told the Marietta Daily Journal.
In fact, water alone does not kill Ebola. Soap and water does. So does chlorine and bleach, experts added.
"As with other infectious diseases, one of the most important preventive measures is frequent hand-washing. Use soap and water, or use alcohol-based hand rubs containing at least 60% alcohol when soap and water aren't available," the Mayo Clinic said about the prevention and spread of Ebola infection.
"The U.S. must immediately stop all flights from EBOLA infected countries or the plague will start and spread inside our 'borders.' Act fast!" -- Real estate mogul Donald Trump said on Twitter.
Most public health experts oppose such a ban.
"Many nations have banned flights from other countries in recent years in hopes of blocking the entry of viruses, including SARS and H1N1 'swine flu,' " wrote Laurie Garrett, a senior fellow for global health at the Council on Foreign Relations. "None of the bans were effective, and the viruses gained entry to populations regardless of what radical measures governments took to keep them out."
No ban will completely stop people moving about the world, experts said.
"It gives us the false assurance that we can ignore the problems that are happening in Africa," Wendy Parmet, director of the Program on Health Policy and Law at Northeastern University School of Law, told National Geographic. "At the end of the day, we can't. And our own safety depends on our getting it right there, not on building the walls."
President Obama this week said he opposes a travel ban.
