What is the deadliest disease on earth?

Answer 1

As far as number of people killed per year, Heart disease is the number one killer in the US.

The most deadly infectious disease in history was the pneumonic form of the plague, the so-called black death of 1347 to 1351. The pneumonic plague,which was a bacterial lung infection, had a mortality (death) rate of 100%.

Another answer:

Ebola is widely considered the "nastiest" of viral diseases. It is compared to AIDS in many ways. Fortunately, Ebola virus is not extremely common, but when there is an outbreak it is noted as extremely deadly. It is considered one of the most Infectious Diseases due to it being able to spread quite easily through the transaction of body fluids (a dirty needle is a major cause, and, like AIDS, it is noted for its ability to travel through sexual intercourse. This is more famous for Ebola's twin- less deadly- virus, Marburg). Ebola is also able to travel in the air, but it does so with difficulty.

There's never been a major outbreak outside of Africa, though small occurrences due pop up around the world. Marburg- the twin virus- is named for its breakout in Marburg Germany.

Ebola- not counting Marburg- has two prominent subspecies, but a few more: Ebola Sudan and Ebola Zaire.

Marburg is the least deadly, with a mortality rate below 50%.

Sudan is slightly worse, with a mortality rate just below 70%.

Zaire is considered the worse, with a mortality rate measuring above 90%.

The events recorded in the true story-novel, "The Hot Zone", are a chronicle of the story of Ebola outbreaks. It culminates in the climax of the novel outside of Washington DC where an outbreak of Ebola was barely dodged. The subspecies there was particularly deadly toward non-human primates and was discovered in the Reston monkey house in the suburb of Reston.

Ebola is perhaps not the deadliest virus due to its uncommon nature and its inability to spread as much as HIV (the virus that causes AIDS), but it is perhaps the most violent. Victims of Ebola suffer internal bleeding and external bleeding, severe hemorrhaging, mental damage, are considered physically "drained" and suffer from vomiting of Ebola infected blood. Their ribcage are noted for collapsing into themselves along with their flesh. It is also a point of importance that, at least in non-human primates (specifically, African Green Monkeys) their flesh "melts" into a form similar to "soup."

So yes, Ebola is widely considered not only the most deadly virus in the world, but perhaps the worst disease. It is not as much of an efficient killer as a heart attack or even cancer, but those are not viral or bacterial diseases.

Answer 2

The most deadly disease in the world is called tuberculosis. Almost Two billion people are infected with it.

Its SMALL POX

By some accounts, smallpox is considered to have killed more people than any other infectious disease. However, thanks to the discovery of the smallpox vaccine, the last known naturally contracted case of the disease was in 1977, according to the World Health Organization (WHO). During its deadliest years, this highly contagious disease killed as many of 30 percent of people who contracted it. Those who survived were often blinded or marked with deep scars. Despite its eradication, smallpox may still pose a threat today, if released as a biological weapon.
