That’s better than being infectious immediately. Quickly scanning wikipedia, I couldn’t find that information and is why I posted the question.
***SNIP*** As you may have also heard, two American healthcare workers at a hospital in Monrovia, Liberia, have been infected with Ebola virus. One of the healthcare workers, a physician who worked with Ebola patients in the hospital, is symptomatic and in isolation. The other health care worker developed fever but no other signs of illness. The physician’s family had been living with him in Liberia. Thankfully, the family members had returned to the United States before the doctor got sick and therefore are not at risk for contracting Ebola or spreading it to anyone here. Out of an abundance of caution, the family is currently on a 21 day fever watch. I want to emphasize that Ebola isn't contagious until symptoms appear. I want to underscore that Ebola poses little risk to the U.S. general population. Transmission is through direct contact of bodily fluids of an infected person or exposure objects like needles that have been contaminated with infected secretions. Individuals who are not symptomatic are not contagious. The mortality rate in some outbreaks can be as high as 90 percent, but in this outbreak, it is currently around 60 percent, indicating that some of our early treatment efforts may be having an impact.
There is a lot of paranoia when it comes to ebola. Horrible as the disease is, there is some good news for us here in the West: Ebola is not easily transmissible, as long as you don't come in direct contact with people who are showing symptoms, or with any of their bodily tissues, bodily fluids, or personal effects that they touched recently after becoming symptomatic (clothing, bedding, cell phones, etc.)(the scary news is that that may also include money). Also, and I believe it (though obviously some don't), victims are not contagious during incubation.
Still, if there is a breakout here, perhaps the best and most prudent policy is to steer clear of sick people, anyone they may have made contact with (yes, even those who may only be incubating), and anything they touched. And given that money may be a vector, the government has absolutely no business bringing ebola victims here!
