Why is 2014 Ebola outbreak so deadly?

The 2014 Ebola outbreak is caused by Zaire ebolavirus. Zaire ebolavirus is the most deadly subtype of all the five Ebola viruses. Zaire ebolavirus has a case fatality rate of 60-90%. Currently there is a lack of licensed Ebola virus vaccines as well as pre- and post-exposure treatments.

Till now, control of this new strain of the Zaire Ebola subtype is proving difficult for several reasons. The geographical spread of cases and movement of people in and between the four countries presents a huge challenge in tracing those who might be infected. All four countries have weak health systems, including severe human resource constraints. That may have helped the virus disperse geographically, and it made it difficult to track down people who might be infected. Furthermore, the region's health workers have never dealt with Ebola before and need training in infection-control measures to protect themselves and to provide adequate care for patients. Susannah Locke said, "In many ways, how well a country can deal with an Ebola outbreak comes down to basic health-care practices and public education."

What should we know about 2014 Ebola outreak?

1, Ebola doesn't change as fast as some other viruses. The Ebola virus that's causing the current outbreak is a known quantity. And there's no expectation that it will change significantly. Ebola was first discovered in 1976 and has stayed pretty much the same ever since. The severity of the current Ebola outbreak is not because the virus itself has gotten any worse, but because the situation that the virus is in is so bad.

2, Ebola spreads through close contact. Ebola doesn't tend to travel through the air like the flu and other respiratory illnesses. In order to catch Ebola, you have to touch the bodily fluids (such as sweat, vomit, diarrhea, blood, urine, or semen) of an Ebola patient — dead or alive. Because Ebola can stay alive on a surface for at least several days, you could also get it from touching bedding or other inanimate objects contaminated with those bodily fluids. After that, you would have to get the virus into your body by, for example, touching food and eating it.

3, People can survive Ebola. The current outbreak is so bad because it's happening in places with poor health infrastructure.

4, If Ebola came to other countries, it probably wouldn't get very far. Whether it will be a giant outbreak in new location, a lot depends on how quickly the virus is noticed and how prepared the public health system is to deal with it.
