What is the prognosis of Ebola hemorrhagic fever?

The prognosis of Ebola hemorrhagic fever is often poor; the death rate of this disease ranges from 50%-100%, and those who survive may experience the complications listed above. However, early diagnosis and treatment of Ebola may greatly increase the patient's chance for survival. Unfortunately, this disease has been mainly located in countries where medical care is often difficult to obtain, especially in rural areas of Africa. Current statistics available on the ongoing 2014-2015 outbreak (as of May 8, 2015) of Ebola are summarized below:

  • Total suspected, probable, and confirmed infections worldwide equal 26,683 and total deaths equal 11,022 for a death rate or death toll of 41%. However, new infections (at a low level) and deaths of current patients are likely to change these numbers as the epidemic slows.

Is it possible to prevent Ebola hemorrhagic fever? Is there a vaccine for Ebola hemorrhagic fever?

The main way to prevent getting Ebola hemorrhagic fever is to not travel to areas where it is endemic and by staying away from any patients who may have the disease. Medical caregivers may protect themselves from becoming affected by strict adherence to barriers to the virus (wearing gloves, gowns, goggles, and a mask). Currently, there is no commercially available vaccine against the Ebola virus strains that cause Ebola hemorrhagic fever in humans.

What is the latest research on Ebola hemorrhagic fever?

Research on developing a vaccine against Ebola viruses is ongoing; successful vaccines have been developed that work in experimental animals (mice and guinea pigs but not against macaques monkeys). With new and larger outbreaks of Ebola hemorrhagic fever possible, researchers are intensely working to develop an effective vaccine utilizing genetically modified viruses, recombinant viruses, and inactivated Ebola viruses. Unfortunately, none are currently available but at least two are entering clinical trials and other trials are ongoing. A vaccine and/or new treatments are likely to be available in the near future.
