The term, influenza, from the Italian word meaning "influence", was coined AD. By Cholera cases had been cut down dramatically, although it was still a constant in India. In the past, black rats were the most commonly infected animals and hungry rat fleas would jump from their recently-dead rat hosts to humans, looking for a blood meal.
Today its impact varies widely across the world—while in an estimated 1. During the 18th century at least three pandemics occurred, and Possibly typhoid fever killed a quarter of the Athenian troops, and a quarter of the population over four years. British physician John Snow, while working in a poor area of London, tracked cases of cholera and eventually succeeded in identifying contaminated water as the means of transmission for the disease.
It rapidly spread via Russia throughout Europe known as the "Russian Flu". This virus was different because it moved directly from chickens to people, rather than having been altered by infecting pigs as an intermediate host.
Deeply affected Russiawith over a million deaths. This disease fatally weakened the dominance of Athensbut the sheer virulence of the disease prevented its wider spread; i.
The fatality was recorded at over 25 million people or one-fourth of the entire population. The last form, septicemic plague, happens when the bacteria enter the blood from the lymphatic or respiratory system.
Introduced diseases, notably smallpox, nearly wiped out the native population of Easter Island. The pandemic caused approximately 10 million deaths Khan, Originating in Cameroon and first recognized as a disease inthe earliest documented case is believed to be in in the Congo.
The findings suggested Europeans could have carried the nonvenereal tropical bacteria home, where the organisms may have mutated into a more deadly form in the different conditions of Europe.
The plague went on to eliminate a quarter to a half of the human population that it struck throughout the known world.
An estimated one third of the global population are carriers of the TB bacterium, and each year nine million fall sick and one million die — many also AIDS victims. Plague of AthensBC. The disease was named after Marcus Aurelius Antoninus, one of two Roman emperors who died from it.

The Black Death was one of the most devastating pandemics in human history, resulting in the deaths of an estimated 75 to million people.
Spreading throughout the Mediterranean and Europe, the Black Death is estimated to have killed 30–60% of Europe's total population. Pandemics, which are large disease outbreaks that affect several countries, pose major health, social, and economic risks.
A severe pandemic can result in millions of deaths, and even the most conservative estimates suggest that pandemics destroy up to 1% of global GDP, which is comparable to other top-priority threats, such as climate change.
Deadly Diseases: Epidemics throughout history.
Experts warn a global pandemic will halt humanity as we know it in the next 20 to 30 years.
History of Europe - Romans: The original Mediterranean population of Italy was completely altered by repeated superimpositions of peoples of Indo-European stock. The first Indo-European migrants, who belonged to the Italic tribes, moved across the eastern Alpine passes into the plain of the Po River about bce.
Later they crossed the Apennines and eventually occupied the region of Latium.
A pandemic is an epidemic occurring on a scale which crosses international boundaries, usually affecting a large number of people.
Pandemics can also occur in important agricultural organisms (livestock, crop plants, fish, tree species) or in other organisms.Download
