Another source of chest pain is the esophagus, the tube that carries food from your mouth to your stomach. Acid backing up (refluxing) from the stomach into the esophagus causes pain that can mimic a heart disorder, as can spasms of the esophagus.
Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness in humans. The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. The average EVD case fatality rate is around 50%.
Deadly Diseases: The current epidemic in West Africa is the largest Ebola outbreak on record. In less than a year, the virus has killed more than 4,000 people. The CDC has said that in a worst-case scenario the disease could infect as many as 1.4 million people by January. If the current death rate holds steady around 70%, that could mean up to 980,000 by next year. See how this epidemic compares with others throughout history.
