Time and again, we humans have been reminded that we are mere mortals. And nothing is a worse reminder than diseases capable of wiping entire towns out of existence. Deadly diseases have been around since the beginning of time, claiming hundreds of thousands of lives at different times throughout the course of human history. There is simply no escaping death with these 10 deadliest diseases.
1. Ebola Virus
There is no cure for Ebola and no vaccine that could protect you from getting infected. With a fatality rate that sometimes soars to 90 percent, you should be very afraid of this virus.

Ebola Virus Disease (EVD) first made itself known in 1976 when a 44-year old schoolteacher from Yambuku showed symptoms of malaria. It was later discovered to be one of four Ebola viruses that cause human disease. An outbreak occurred in Yambuku, Democratic Republic of Congo, and Nzara, Sudan in the same year – the first two ever recorded of the disease. Of the four known Ebola viruses, it caused the most outbreaks and has the highest fatality rate.
At least 5,000 people have died from the ongoing outbreak that plagued West Africa since March 2014. Guinea, Sierra Leone, and Liberia are the biggest hit countries. According to the World Health Organization, this is the largest and most complex Ebola outbreak since it first appeared in 1976, infecting more people and causing more deaths compared to all other Ebola outbreaks combined.
Ebola infection is characterized by the sudden onset of fever, headache, sore throat, and muscle pain. Later on, the disease causes diarrhea, vomiting, and rash. Its most serious symptoms include impaired liver and kidney function, and internal and external bleeding. Without proper care, an infected person could die out of complications.
