Final answer:
No humans have died from the Reston ebolavirus strain, whereas the Ebola Zaire strain was responsible for the significant death toll during the 2014 West Africa epidemic.
Step-by-step explanation:
No humans have died from the Reston ebolavirus strain. While the 2014 Ebola virus epidemic in West Africa was the largest in history, with over 28,000 cases and 11,302 deaths, this was primarily due to the Ebola Zaire strain. The Ebola outbreak reached several West African countries, including Liberia and Sierra Leone, and caused worldwide concern due to the high mortality rates and rapid spread of the disease. However, the Reston strain, first discovered in the Philippines, differed from African strains as it is not known to cause disease in humans. In contrast, the strain that caused the epidemic in West Africa had a very high mortality rate depending on the strain, with reports ranging from 23 percent to 90 percent. The international community responded with medical support and unregistered treatments in an attempt to control the outbreak.
It is important to distinguish between the different strains of Ebola, as they vary in virulence and transmission. For example, while the Reston strain is potentially lethal to nonhuman primates, it has not been linked to human fatalities. The contrast between the lack of human fatalities from Ebola Reston and the significant death toll from the Ebola Zaire strain during the West Africa epidemic underscores the variability of this virus group.
