The 1918 Pandemic: An Infectious Disease

A pandemic is an outbreak of an infectious disease that spreads through human populations across a large region, whether that be multiple continents or worldwide. In order to be considered a pandemic, a disease must cross international boundaries and be contagious or infectious. Pandemics are usually caused by a new virus strain that humans have either very little or no immunity against. This contagious virus spreads easily from person to person, through direct contact or coughing and sneezing. A serious illness is caused worldwide from the virus, wiping out entire populations. Some of the deadliest pandemics include the Black Death, the Spanish influenza, and the second cholera pandemic. The Bubonic Plague, known as The Black Death, originated

Although it’s still unknown exactly where the specific strain of influenza that caused the pandemic came from, the 1918 flu was first observed in Europe, the U.S., and parts of Asia before spreading around the world in a matter of months. Spain was one of the earliest countries to be hit by the disease, giving it the name the Spanish Flu, despite the fact that it wasn’t isolated in one place. An estimated 20 million to 50 million victims were killed by the flu, though other estimates run as high as 100 million. It’s impossible to know exact numbers due to the lack of medical records kept at the time. Surprisingly, many of these victims were previously healthy, young adults that were normally resistant to that type of contagious disease. Like many other illnesses during this time, doctors had no idea what caused the flu or how to treat it because there were no effective vaccines or drugs to treat the flu. Making matters worse, World War l had left most of America with a shortage of physicians, and many of those available came down with the flu themselves. Schools and homes had to be used as makeshift hospitals run by medical students because hospitals in some areas were so crammed with patients. The public health departments imposed quarantines and ordinances in an attempt to confine the spread of the disease. Citizens were ordered to wear

Unlike the first cholera pandemic in 1817, the second one also affected countries in Europe and North America in addition to Asia. Of the seven total cholera pandemics, many consider this one the greatest of the 19th century. Cholera caused more deaths, more quickly than any other epidemic disease of the 1800s. It is an infectious disease that causes severe diarrhea that can lead to dehydration and death if untreated. Eating food or drinking water contaminated with a bacterium called Vibrio cholerae causes cholera. After the first pandemic had diminished throughout Asia by1824, the disease began spreading again from Bengal in 1826. It began with outbreaks in the Ganges River of Bengal and quickly spread throughout most of India. It had moved into Afghanistan and Persia by 1829 and surfaced in Russia in August of that year. From Russia, the disease travelled to Poland and eventually Hungary, Germany, Berlin, England, Scotland, and Wales. While the disease was penetrating most of Europe, it had also reached areas in Mesopotamia and the Arabian Peninsula by 1831. Thousands of Muslim pilgrims from Mecca died from the disease and carried it into Palestine, Syria, and Egypt that year. Mecca continued to be infected by cholera until about 1912. The disease also reached Portugal in 1833, from an English ship that docked in Portugal. Cholera’s path east of India remains
