How long was the swine flu outbreak?
The 2009 swine flu pandemic was an influenza pandemic that lasted for about 19 months, from January 2009 to August 2010, and was the second of two pandemics involving H1N1 influenza virus (the first being the 1918–1920 Spanish flu pandemic)..
When was the last pandemic flu?
The most recent pandemic occurred in 2009 and was caused by an influenza A (H1N1) virus. It is estimated to have caused between 100 000 and 400 000 deaths globally in the first year alone.
Where did the Spanish flu start?
While it’s unlikely that the “Spanish Flu” originated in Spain, scientists are still unsure of its source. France, China and Britain have all been suggested as the potential birthplace of the virus, as has the United States, where the first known case was reported at a military base in Kansas on March 11, 1918.
Is there a vaccine for swine flu?
Vaccines have been developed to protect against the virus that causes swine flu. There are two different brands of vaccine – Pandemrix and Celvapan. Many people given the Pandemrix vaccine will only need one dose. People who have the Celvapan vaccine will need two doses three weeks apart.
Did h1n1 start in USA?
In the spring of 2009, a novel influenza A (H1N1) virus emerged. It was detected first in the United States and spread quickly across the United States and the world. This new H1N1 virus contained a unique combination of influenza genes not previously identified in animals or people.
Where did the swine flu start?
The swine-origin influenza A (H1N1) virus that appeared in 2009 and was first found in human beings in Mexico, is a reassortant with at least three parents. Six of the genes are closest in sequence to those of H1N2 ‘triple-reassortant’ influenza viruses isolated from pigs in North America around 1999-2000.
When was the last pandemic in the United States?
The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919.
How long did the Spanish flu last in America?
Just two weeks after the first reported case, there were at least 20,000 more. The 1918 flu, also known as the Spanish Flu, lasted until 1920 and is considered the deadliest pandemic in modern history.
Is the Spanish flu still around today?
Descendants of the 1918 influenza virus still circulate today, and current seasonal influenza vaccines provide some protection against the 1918 virus.
Why did Spanish flu kill so many?
Scientists offer several possible explanations for the high mortality rate of the 1918 influenza pandemic. Some analyses have shown the virus to be particularly deadly because it triggers a cytokine storm, which ravages the stronger immune system of young adults.
What country was most affected by the Spanish flu?
The first occidental European country in which the pandemic spread to large sectors of the population, causing serious mortality, was Spain. The associated influenza provoked in Madrid a mortality rate of 1.31 per 1000 inhabitants between May and June (1918).
How many people died in the 1918 pandemic?
It is estimated that about 500 million people or one-third of the world’s population became infected with this virus. The number of deaths was estimated to be at least 50 million worldwide with about 675,000 occurring in the United States.
How did the 2009 swine flu pandemic start?
The 2009 swine H1N1 flu pandemic — responsible for more than 17,000 deaths worldwide — originated in pigs from a very small region in central Mexico, a research team headed by investigators at the Icahn School of Medicine at Mount Sinai is reporting.
How many pandemics have there been in history?
Throughout human history, there have been a number of pandemics of diseases such as smallpox and tuberculosis. The most fatal pandemic in recorded history was the Black Death (also known as The Plague), which killed an estimated 75–200 million people in the 14th century.
When did the swine flu first appear?
The swine flu was initially seen in the US in April 2009, where the strain of the particular virus was a mixture from 3 types of strains. Six of the genes are very similar to the H1N2 influenza virus that was found in pigs around 2000.
How long did the 1918 flu last?
While the global pandemic lasted for two years, a significant number of deaths were packed into three especially cruel months in the fall of 1918.
What was the first pandemic?
The earliest recorded pandemic happened during the Peloponnesian War. After the disease passed through Libya, Ethiopia and Egypt, it crossed the Athenian walls as the Spartans laid siege. As much as two-thirds of the population died.
Why is the flu not considered a pandemic?
Pandemic flu is different and can be much worse. It can cause a worldwide outbreak of a new form of flu virus, which spreads easily from person to person because they have no immunity. Pandemic flu occurs when a flu virus goes through changes (called “mutations”) that create a new virus the body has never encountered.

What animal did the Spanish flu come from?
The 1918 influenza pandemic caused an estimated 50 million to 100 million deaths worldwide. The virus that caused the 1918 influenza pandemic probably sprang from North American domestic and wild birds, not from the mixing of human and swine viruses.
