How old is the flu?
When was the flu first discovered
In 1933, British researchers Wilson Smith, C.H. Andrewes and P.P. Laidlaw at London's National Institute for Medical Research (NIMR) made a breakthrough when they isolated and identified the influenza virus.

How did the flu start
Origin of Pandemic Influenza Viruses. The predominant natural reservoir of influenza viruses is thought to be wild waterfowl (Webster et al., 1992). Periodically, genetic material from avian virus strains is transferred to virus strains infectious to humans by a process called reassortment.

When did the flu start in America
The first confirmed cases originated in the United States. Historian Alfred W. Crosby stated in 2003 that the flu originated in Kansas, and author John M. Barry described a January 1918 outbreak in Haskell County, Kansas, as the point of origin in his 2004 article.
What year did influenza start and end
The flu pandemic lasts from 1918 to 1920. From spring of 1918 to spring of 1919, the flu causes more than 550,000 deaths in the U.S. and more than 20 million deaths worldwide. In the fall of 1918 at Mayo Clinic, people with the flu and other contagious illnesses are cared for in the isolation hospital.

1. The Black Death: Bubonic Plague. The Black Death ravaged most of Europe and the Mediterranean from 1346 until 1353.
What animal did the flu come from
The influenza virus might have started in fish. Researchers trawling genetic databases have discovered a distant relative of influenza viruses — which are responsible for seasonal flu, not to mention the avian flu roiling the globe — in sturgeon1.
How long was the flu a pandemic
The influenza pandemic of 1918–19, also called the Spanish flu, lasted between one and two years. The pandemic occurred in three waves, though not simultaneously around the globe. In the Northern Hemisphere, the first wave originated in the spring of 1918, during World War I.
How many died in the 1957 flu pandemic
It was first reported in Singapore in February 1957, Hong Kong in April 1957, and in coastal cities in the United States in summer 1957. The estimated number of deaths was 1.1 million worldwide and 116,000 in the United States.
What was the biggest flu in history
The microscopic killer circled the entire globe in four months, claiming the lives of more than 21 million people. The United States lost 675,000 people to the Spanish flu in 1918-more casualties than World War I, World War II, the Korean War and the Vietnam War combined.
Is COVID worse than the Black plague
That makes it worse in absolute terms than most influenza pandemics in history, except 1918's; worse than the seven cholera pandemics of the 19th and early 20th century; but much less bad than HIV, 1918, or the Black Death and associated bubonic plague outbreaks.
What was the worst sickness in history
1. The Black Death: Bubonic Plague. The Black Death ravaged most of Europe and the Mediterranean from 1346 until 1353. Over 50 million people died, more than 60% of Europe's entire population at the time.

What disease kills the fastest
The world's fastest killer is ischaemic heart disease, responsible for 16% of the world's total deaths.Cerebrovascular diseases such as stroke are also extremely fatal within minutes of their onset.
Why does flu exist
Answer: Influenza is a virus that's spread from person to person. It originates, actually, among birds and other animals such as pigs, and new viral strains of influenza come to this country and to Europe from Southeast Asia. That's the global pattern.
How long did COVID last
Most people with COVID-19 get better within a few days to a few weeks after infection, so at least four weeks after infection is the start of when Long COVID could first be identified. Anyone who was infected can experience Long COVID.
What pandemic was before COVID
Today, the COVID-19 pandemic is frequently compared with the influenza pandemic of 1918-1919. The destruction caused by that pandemic a century ago may sound familiar. Yet, direct comparisons of the 1918 flu pandemic and the COVID-19 pandemic may not be completely fair, according to one scientist.
