What is the deadliest disease in the world?

As an expert in epidemiology, I can provide you with an informed answer regarding the deadliest diseases in the world. It's important to note that the deadliest disease can be measured in various ways, such as the number of deaths per year, the total number of deaths in history, or the disease's case fatality rate. Smallpox was indeed one of the most deadly diseases in history, causing the death of hundreds of millions of people over centuries. However, it was declared eradicated in 1980 by the World Health Organization after a successful global vaccination campaign. The Spanish Flu of 1918 was a devastating pandemic that infected a significant portion of the world's population and resulted in the deaths of tens of millions of people. The Black Plague, also known as the Black Death, was a pandemic that swept through Eurasia and Africa in the 14th century, killing an estimated 75 to 200 million people. Tuberculosis has been a persistent killer throughout history and remains a significant cause of death worldwide, particularly in developing countries. Malaria is a mosquito-borne disease that continues to be a leading cause of death, particularly in sub-Saharan Africa. Ebola is a rare but severe and often fatal disease, with outbreaks occurring primarily in parts of Africa. Cholera is an infectious disease that can cause severe diarrhea and dehydration, leading to high mortality rates if not treated promptly.
