As far as Africa is considered, Ebola virus is a certain sign of death. The virus carries with itself a high fatality rate, which goes up to 90%. Unfortunately, the continent of Africa faces the full wrath of this deadly disease as it is quite common in remote villages in Central Africa. As of now, Ebola has no licensed vaccine available for clinical use. With no specific treatment available, the death toll is continuously on the rise with every passing year. The disease was discovered in 1976 and even with all the technological developments and medical breakthroughs; the disease is still at large and poses a big threat to mankind.

This viral disease mainly poses a threat to young children. Polio has no known cure, but there are preventive measures known as vaccines which are administered to children to immunize them against this disease and also to stop is from spreading. The disease causes irreversible paralysis, targeting children under the age of 5. Polio disease has been successfully contained to a certain extent and the number pf cases reported has dropped from almost 350,000 in 1988 to around 406 in 2013. The dream of a polio-free world still remains to be realized with Afghanistan, Pakistan, and Nigeria reporting polio cases every year.

2. HIV/AIDS

Lives claimed: 30 Million

Acquired Immunodeficiency Syndrome (AIDS) or Human Immunodeficiency Virus Infection (HIV) is a life-ending life. With no safe cure available yet, millions of people fall victim to this disease every year. HIV targets defense mechanisms in the human body, so the body cannot put up a fight against any disease. HIV is transmitted via unprotected sexual intercourse, sharing of needles, and transfusions of contaminated blood. There are treatments that at most slow down the virus’s progress, however, no complete cure is available.
