The latest outbreak of Ebola virus in west Africa is the worst ever—as of Monday, it had infected more than 1,200 people and claimed at least 672 victims since this spring. Guinea, Liberia and Sierra Leone all have confirmed cases. An official at Doctors Without Borders has declared the outbreak as “totally out of control,” according to NBC News. Unfortunately, doctors have no effective vaccines or therapies. Health care workers can only attempt to support patients’ immune systems (regulating fluids, oxygen levels, blood pressure and treating other infections) to help the afflicted fight off the virus as best they can.
