Top 9 Deadliest Diseases
The world is facing new dangerous epidemics, the wicked Ebola virus which has already killed hundreds of people in Africa. Not the first deadly virus and certainly not the last that have made humanity suffer. The following list has some of the deadliest diseases that were killing people during the centuries.

Small pox has claimed numerous lives and just in the 20th century, and prior to vaccination, the death toll was estimated at nearly 500 million. But then thanks to the improved medicine and the vaccines and vaccination campaigns of the 20th century, smallpox has become one of two infectious diseases that have been declared as completely eradicated.
#3. Yellow fever
Typical for Africa and South America, this disease is transmitted to humans via female mosquitos. It typically involves fever, chills, anorexia, nausea, muscle pain (with prominent backache) and headache, but in most cases subsides after several days. Due to warfare and social disruption across Africa, there has seen a resurgence since the 1980s.
Back in the last two centuries, this disease was known as the disease of the poor people who lived poor lives (in cold and moldy homes and had poor diets). Usually attacking the lungs, TBC is spread by airborne saliva. The classic symptoms of active tuberculosis infection are a chronic cough with blood-tinged sputum, fever, night sweats, and weight loss. Even though today there is cure for it, some form of this disease kills nearly one third of world population.
