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%.
There are five known strains of the Ebola virus, each named for the location of their first recorded outbreak. Ebola-Zaire was the first strain to raise alarm bells in 1976, when it infected 318 people in what is now the Democratic Republic of Congo, killing 280.
