Epidemics throughout history
1.With new health threats on the ri, James Madison looks at epidemics throughout history.
Bacteria and virus have been around since the beginning of life on Earth and many of today’s dias have been existed as long as humans have. It’ s important to look at the spread of dias throughout history to discover the caus and effects of epidemics.
2.----
Scientists now think that Justinian’s Plague was actually a dia called bubonic plague. They estimate that between 25% and 50% of the area’s population died from the dia and think that the epidemic was one of the key caus of the fall of the Roman Empire.

5. In highly populated areas all over Europe, Asia, Africa and the Middle East, one half to on
e third of the population was lost to the Black Death. Less populated areas, mostly in northern Europe, were less verely affected. json
6. Another epidemic that started and spread in similar conditions was the Great Flu Epidemic of 1918( also called the Spanish Flu). It struck near the end of the first World War and continued after the war was finished.
7.-----
8. One epidemic that we haven’t forgotten yet is the SARS epidemic of 2002/2003. it began with an abnormal lung dia in Guangdong Province and spread worldwide after Dr Liu Jianjun came to Hong Kong. He stayed at a hotel where the dia spread to four more people. When the people left the hotel and returned home, they spread the dia to Canada, Hong Kong, Vietnam and Singapore.

10.No one really knew much about SARS as it was completely new to physicians. Doctor
s weren’t sure how to treat it or prevent it and since most people had no natural defences against the dia. It was also harmful to the doctors and purs treating the SARS patients. Hospital staff, especially nurs, made up 21% of the cas.

A Having killed between 25 and 50 million people in 18 months. It is believed to be the most acute worldwide epidemic in history. More people died of the flu than died in the war. Yet, somehow, it has been forgotten by history.
B. Although aspects of modern life, such as widespread air travel, allowed the SARS epidemic to quickly expand across the globe, other aspects, such as improved communication technology and improved medical rearch techniques, allowed health experts the world over to share knowledge and work together to stop the virus in its tracks.
C In the 1330’s, the bubonic plague returned , this time in Asia. It would spread rapidly an
d come to be known as “ The Black Death”. The conditions in much of Asia and Europe –war, climate change, a lack of adequate food, crowded cities and a lack of basic health routines---provided the perfect conditions for the dia to spread worldwide.
D Over nine months, the number of global cas pasd 8,000 and 774 people died. Although the numbers are much smaller than the number for other dias such as TB or flu, which kill millions every year, the outbreak was still very alarming for a few key reasons.
F. Epidemics are described in historical accounts as early as 430 BC and one of the earliest on record is Justinian’s Plague. It happened about 500-550 AD as Roman Emperor Justinian was attempting to rebuild and acquire more land for the Roman Empire. It swept through North Africa, the Middle East and Europe.
