Influenza, also known as “the flu,” is a virus that infects the respiratory tract. Although Influenza is not as severe as many viral infections it's almost the worst for viral infections of the respiratory tract. Typically, when someone is infected with influenza they experience fever (usually 100° to 103°F in adults, but even higher in children) and causes a cough, sore throat, runny or stuffy nose, and also headaches, muscle aches, and usually extreme tiredness. There are sometimes other symptoms such as nausea, vomiting and diarrhea but usually only in rare cases with young children. One other note: The term “Stomach flu” isn’t really caused by the influenza virus.
The average recovery time from the flu is about 1-2 weeks, although

Although Type A viruses undergo both types of changes, Type B only go through the more gradual Type B.
Antigenic shift occurs only occasionally, but when it does large numbers of people or even entire populations have no antibody against the virus. Although this is potentially lethal, the virus can only start a pandemic if it is able to be spread easily. Throughout the 20th century there were three pandemics, one in 1918, one in 1957, and one in 1968. Each of which resulted in large numbers of deaths.
The 1918 pandemic was known as the “Spanish Flu” and was Influenza strain A(H1N1) and it caused the highest known influenza death rate known, 500,000 Americans and 20 million people worldwide.
The 1957 pandemic was known as the “Asian Flu” and was Influenza strain A(H2N2) and caused 70,000 U.S. deaths.
The 1968 Pandemic was known as the “Hong Kong Flu” and was Influenza strain A(H3N2) and caused 34,000 deaths in the U.S.
The emergence of the “Hong Kong Flu” in 1968-1969 marked the beginning of the A(H3N2) days. When this virus first emerged it had the lowest mortality rate in the 20th century. Although this virus first emerged with such a small death rate, it still continues to kill people to this day. Just as when the A(H2N2) virus appeared in 1957 causing the disappearance of the A(H1N1) virus, the appearance of the A(H2N3) virus caused the disappearance of the A(H2N2) virus. After being dormant for almost 30 years, the A(H1N1) virus reappeared and today
At no time was a search for the cure for influenza more frantic than after the devastating effects of the pandemic of 1918. The pandemic killed somewhere between twenty and a hundred million people, making it twenty five times more deadly than the ordinary cough and sneeze flu. The symptoms of this flu
Known as "Spanish Flu" or "La Grippe" the influenza of 1918-1919 was a global disaster.” ("The 1918 Influenza Pandemic." The 1918 Influenza Pandemic. N.p., n.d. Web. 11 Feb. 2017.)
In 1918, at the end of World War I, the Spanish flu struck the US. Research says that the estimated amount of deaths are somewhere between 20-40 million people worldwide. The Spanish flu was one of the most devastating pandemics in modern history. The Spanish flu was something the medical world had never seen and affected the people living in California greatly.
This influenza occurred at the latter point of “World War 1” coming at a vulnerable time for the world. Many people have already died due to the war, and many resources and money has already been consumed. So when the pandemic hit, it hit with a charge that left a great wound in the economy and health of the people not just in the U.S. but the world. People responded by taking more precautions in health and safety, and took radical response in the exterminating of animal populations.
The book “The Great Influenza: The Story of the Deadliest Pandemic in History, written by John M. Barry, covers the progression of the Spanish influenza, especially in the United States. Barry focuses not only on the influenza itself, though, but also on the social influences that allowed the virus to flourish. The book covers how medical practices in the United States had risen up just in time to combat the virus, but, due to societal issues and the war, the doctors struggled in areas where they should have been successful.
Infectious epidemics and pandemics have happened all through mankind's history. “They remain the prime cause of death worldwide and will not be conquered during our lifetimes.” The flu of 1918 was one of the deadliest epidemics in history. “It infected an estimated 500 million people worldwide–about one-third of the planet’s population at the time–and killed an estimated 20 million to 50 million victims. More than 25 percent of the U.S. population became sick, and some 675,000 Americans died during the pandemic.” No one knew how the virus spread, there were no antibiotics to fight it, and no flu shots to prevent it. In the final year of World War I, it struck terror in the hearts of people all across Europe and left more death in its wake than the combined military actions of the combatants. “It killed more Americans in a few months than World War I, World War II, the Korean War, and the
There have been about 20 million reported deaths due to the influenza of 1918. The doctors were too overwhelmed by the many cases they had to care for, which brought about many unreported cases, causing this minuscule number. One fateful day in October 759 people died in Philadelphia (Kolata 19-20). The epidemic spread so far so fast that public officials became frantic looking for ways to fend off the virus. Arrests were made for spitting and coughing, public meetings were prohibited, and a series of medical procedures were all attempts to prevent the virus from entering victims’ lungs (Persico 83).
The 1918 flu pandemic was an unusually deadly influenza pandemic, the first of the two pandemics involving H1N1 influenza virus. It infected 500 million people across the world, including remote Pacific islands and the Arctic, and killed 50 to 100 million of them—three to five percent of the world’s population—making it one of the deadliest natural disasters in human history.
Many historians call the Great Influenza Pandemic of 1918 the deadliest disease outbreak of all time. As many as 100 million people were killed as a direct result of this disease (Taubenberger 1). The Great Pandemic affected everyone, the prosperous and the poor, developed and underdeveloped nations. Entire villages in Alaska were wiped out because of the viral disease (Public Health Service). The Influenza Pandemic of 1918 was caused by World War One, a high volume of immigration, and poor sanitary conditions.
Influenza, an innocent little virus that annually comes and goes, has always been a part of people’s lives. Knowing this, one would not believe that it has caused not one, not two, but three pandemics and is on its way to causing a fourth! The Spanish flu of 1918, the Asian flu of 1957, and the Hong Kong
Avian influenza is a disease that has been wreaking havoc on human populations since the 16th century. With the recent outbreak in 1997 of a new H5N1 avian flu subtype, the world has begun preparing for a pandemic by looking upon its past affects. In the 20th Century, the world witnessed three pandemics in the years of 1918, 1957, and 1968. In 1918 no vaccine, antibiotic, or clear recognition of the disease was known. Killing over 40 million in less than a year, the H1N1 strain ingrained a deep and lasting fear of the virus throughout the world. Though 1957 and 1968 brought on milder pandemics, they still killed an estimated 3 million people and presented a new
One of the most virulent strains of influenza in history ravaged the world and decimated the populations around the world. Present during World War I, the 1918 strain of pandemic influenza found many opportunities to spread through the war. At the time, science wasn’t advanced enough to study the virus, much less find a cure; medical personnel were helpless when it came to fighting the disease, and so the flu went on to infect millions and kill at a rate 25 times higher than the standard.
In two years between 1918 and 1919, A pandemic of influenza swept mercilessly over the planet, killing millions which stood in its path. Miraculously, the exact origin of the pandemic is unclear. What is exceedingly clear, however, is that often the actions of man aided in the spread of the virus, whether due to inadvertent endangerment, close quarters, religious principles, or failure to recognize the true threat that influenza posed.
The website Flu.gov says that “historically, the 20th century saw 3 pandemics of influenza, and the 21st has experienced 1 flu pandemic.”
Influenza, normally called “the flu”, the influenza virus causes an infection in the respiration tract. Even though the influenza virus can sometimes be compared with the common cold. It also can cause a more severe illness or death. During this past century, pandemics took place in 1918, 1957, and 1968, in all of these cases there where unfortunately many deaths. The “Spanish flu” in 1918, killed approximately half a million people in the United States alone. It killed around 20 million worldwide. The “Asian flu” in 1957, in the United States their 70,000 people died. In 1968 the “Hong-Kong flu” There where 34,000 deaths in the United
