The overall prognosis for patients with Ebola virus infection is poor. However, those who survive for 2 weeks often make a slow recovery.
With the exception of the Reston strain, Ebola virus is associated with very high morbidity and mortality among patients who present with clinical illness, though these vary according to the causative species. The most highly lethal Ebolavirus species is Zaire ebolavirus, which has been reported to have a mortality rate as high as 89%. Sudan ebolavirus also has high reported mortality, ranging from 41% to 65%.

United States statistics
Ebola virus is not endemic in the United States. However, several human infections with the Reston strain of Ebola have been acquired by animal care workers at primate holding facilities within the United States. Fortunately, the Reston strain has not demonstrated pathogenic effects in humans. Others at potential risk are laboratory workers who work with infected animals or with the virus in tissue culture.
International statistics
Ebola and Marburg viruses are responsible for well-documented outbreaks of severe human hemorrhagic fever, with resultant case mortalities ranging from 23% for Marburg virus to 89% for Ebola virus in which more than one case occurred (see Tables 1, 2, 3, 4, and 5 below).
The current (2014) Ebola virus outbreak is significant and primarily involves 4 African countries—Guinea, Liberia, Sierra Leone, and Nigeria. As of September 4, 2014, 3069 total suspected or confirmed cases (1752 laboratory-confirmed) had been reported in these countries, resulting in 1552 deaths. Based on genetic analysis, the virus is 97% identical to the Zaire ebolavirus identified in recent (earlier in 2014) cases in Gabon and the Democratic Republic of the Congo.[11, 12] At least 3 Americans in Africa have been infected with Ebola in the current outbreak, one of whom has died of the disease.[13]
The current outbreak has prompted the Centers for Disease Control and Prevention (CDC) to issue a level 3 travel advisory (avoidance of nonessential travel) to Sierra Leone, Guinea, and Liberia. Those who do travel to these countries are advised to avoid contact with the blood and body fluids of people with known Ebola virus infection.[3]

Individuals considered at risk for Ebola hemorrhagic fever include persons with a travel history to sub-Saharan Africa, persons who have recently cared for infected patients, and animal workers who have worked with primates infected with African-derived Ebola subtypes. In 2011, Uganda experienced a reemergence of the disease.[16]
Age-related demographics
In the 1995 outbreak in Kikwit, DRC, infection rates were significantly lower in children than in adults. During this outbreak, only 27 (8.6%) of the 315 patients diagnosed with Ebola virus infection were aged 17 years or younger. This apparent sparing of children occurs even though 50% of the population of the DRC is younger than 16 years. Although definitive evidence is lacking, epidemiologic evidence suggests that children are less likely to come into direct contact with ill patients than adults are.
Other viral hemorrhagic syndromes, such as Crimean-Congo hemorrhagic fever and hantavirus infections, also show a predominance of adult patients and a relative sparing of young children.
Sex-related demographics
Ebola virus infection has no sexual predilection, but men and women differ with respect to the manner in which direct exposure occurs.
Men, by the nature of their work exposure in forest and savanna regions, may be at increased risk of acquiring a primary infection from gathering “bush meat” (primate carcasses) for food, as well as an unknown vector or vectors. Evidence from Africa and the Philippines is compatible with bats being a principal vector of Ebola virus.
Because women provide much of the direct care for ill family members and are involved in the preparation of the bodies of the deceased, they may be at increased risk of acquiring Ebola virus infection through their participation in these activities. However, men and women who are medical healthcare providers seem to share a high and equal risk of infection.
Race-related demographics
Because most cases of Ebola virus infection have occurred in sub-Saharan Africa, most patients have been black. However, no evidence exists for a specific racial predilection.
