What Made The 1918 Flu So Deadly

The first phase the least deadly. A number of factors all came together at once.

Scientists Discover Why The 1918 Flu Pandemic Was So Deadly Time

The flu virus comes in several varieties based.

What made the 1918 flu so deadly. In the tail end of WWI people were moving all over. The 1918 flu killed at least 50 million people more than died from battle in World War I. One of the first registered cases was Albert.

A group of three genes enabled the virus to weaken a victims bronchial tubes and lungs. However the second wave showed a markedly elevated mortality rate which accounted for the majority of the death toll. Soldiers were coming home or being re-stationed reliefrepair crews were mobilizing etc.

Then suddenly something big happened. The flu had plenty of chances to spread. Several dozen soldiers died there.

MILWAUKEE Since the Spanish flu swept across the globe in 1918 killing millions of healthy young adults researchers have wondered what it was about this particular strain of flu. WASHINGTON Reuters - Researchers have found out what made the 1918 flu pandemic so deadly -- a group of three genes that lets the virus invade the lungs and cause pneumonia. Bible Locust Swarms What made the 1918 flu so deadly-----The purpose of our channel is to create informational videos.

Most deaths in the 1918 influenza pandemic were due not to the virus alone but to common bacterial infections that took advantage of victims weakened immune systems according to two new. According to the PBS documentary Influenza 1918 more than 100 soldiers had reported to the infirmary by noon. In 1918 flu patients pneumonia often quickly developed and killed people by the second day.

However even it is the case it just means the flu strain has the potential to become deadly. When the Spanish flu first appeared in early March 1918 it had all the hallmarks of a seasonal flu albeit a highly contagious and virulent strain. Within a week that number had quintupled.

Genetic material from bird flu virus picked up just before 1918 They found that a human H1 virus that had been circulating among humans since around. Influenza A also has an RNA-based genome which allows it to frequently mutate similar to the rapid changes that made HIV difficult to treat. Almost 90 years later in 2008 researchers announced theyd discovered what made the 1918 flu so deadly.

Efforts for the First World War had taken over so rampant spread was facilitated by troop movements. With this video our goal is t. But to explain the 1918 pandemics unusual virulence many scientists had come to believe the virus killed by provoking an overzealous destroy-the-village-to-save-it immune response especially in young adults with robust immune systems.

The world was more interconnected than it ever had been. Antibiotics like penicillin discovered in. It is thought that another key mutation occurred between the first and second wave which helped the virus better.

So there was a whole generation of Spanish flu orphans The flu raged in three waves beginning in 1918 with the last ebbing around the summer of 1919. It has long been recognized that most flu deaths are due to pneumonia caused by secondary bacterial infections. These are the H and the N that appear respectively in the taxonomy of flu strains such as the 2009 H1N1 swine flu pandemic the 1918 pandemic was likewise caused by an H1N1 virus.

Why was the 1918 Spanish flu so deadly. It was a new type of flu. Many flu deaths are also caused by secondary bacterial infections that take root in the weakened body leading to pneumonia.

A major study from 2014 led by Professor Michael Worobey found that the H1 flu virus had entered the human population just 10 or 15 years prior to 1918. In its first wave the 1918 flu was just a little more lethal than seasonal flu.
