Here on Roosevelt Island in New York City, the Smallpox Hospital, a historic ruin, is an icon. It’s lit at night and stands out like a ghost to anyone passing along the East River. Its main section was designed by legendary architect James Renwick.
But trailing out behind this decaying structure is a story that makes it more than it appears on an autumn afternoon with vines of rust-red curled along its facade.

The Smallpox Epidemic in America was a devastating pandemic that killed thousands of people. The disease was highly contagious, and there was no cure. The epidemic began in 1775 and returned in waves of death until 1882.
There were several outbreaks of Smallpox throughout the years, with the most deadly one happening in 1857. The Smallpox Epidemic in America was finally brought to an end thanks to the development of a vaccine by Dr. Edward Jenner. Today, there are no known cases of Smallpox anywhere in the world.
The Smallpox Epidemic in America was a devastating pandemic that killed thousands of people
The smallpox epidemic was one of the most devastating pandemics to ever hit America. Smallpox is caused by the variola virus. The virus is spread through direct contact with an infected person or through contact with contaminated objects.
Symptoms of smallpox include fever, headache, muscle pain, and a rash. The rash starts as small red bumps and eventually turns into pus-filled blisters. In severe cases, smallpox can lead to death.
The smallpox epidemic began in America in the 1600s and quickly spread across the country, killing many and scarring many more for life. It had a profound impact on American society and played a role in shaping the country that we know today.
An estimated 60,000 Americans died in the first wave, which was especially deadly to young children and pregnant women.
The epidemic began in the New England colonies and quickly spread throughout the country, hitting Philadelphia particularly hard. In response to the crisis, communities set up quarantine stations and hospitals, and vaccination programs were established to try to control the spread of the disease.
However, these measures were largely unsuccessful in stemming the tide of death. The smallpox epidemic had a profound impact on American society, causing widespread panic and leading to a decline in population growth. It also had a lasting impact on public health policy, spurred by the realization that more needs to be done to prevent and control deadly diseases.
The disease was highly contagious and there was no cure
Smallpox was a highly contagious disease that killed millions of people around the world. There was no cure for smallpox, and the only way to prevent it was to vaccinate people.
However, even with vaccination, smallpox was still a major problem. In the early 1800s, smallpox epidemics killed hundreds of thousands of people in Europe and Asia.
In the United States, smallpox outbreaks occurred every few years, and vaccination was not mandatory. As a result, many people died from smallpox.
In 1803, President Thomas Jefferson ordered that all American citizens be vaccinated against smallpox. His library catalog indicates that he followed the work of the British physicians Edward Jenner and John Lettsom in their experiments with the use of milder cowpox as an effective immunization against smallpox.
This decree helped to reduce the number of smallpox deaths in the United States. However, smallpox continued to be a problem in other parts of the world.
In 1967, the World Health Organization declared that smallpox had been eradicated from the human population. This was a major achievement in public health, and it showed that it is possible to eradicate a disease from the world.
How Do Vaccines Work in Preventing Infections?
Vaccines work by protecting people from diseases. They do this by injecting a person with a “dead” or “modified” form of the virus. As that person’s immune system fights off the “dead” virus, the immune system is also preparing to fight the live, or actual, virus.
If you are ever exposed to the disease, your immune system is primed and ready to fight it off, because it has done so before. Vaccines have been responsible for the eradication of diseases like smallpox and polio, and have greatly reduced the incidence of others, like measles, mumps, rubella, and chickenpox.
The Worst of the American Epidemic Began in 1775 and Lasted Until 1882
Most Americans have never heard of the smallpox epidemic that began in 1775 and lasted until 1882. Yet, this was the worst American epidemic in terms of both mortality and morbidity.
The smallpox epidemic began in the American colonies and quickly spread throughout the country. Despite its devastating effects, the smallpox epidemic eventually ended on its own.
But this was not due to any medical intervention; rather, it is thought that the smallpox virus simply mutated into a less deadly form.
As a result of this epidemic, many Americans became distrustful of government officials and medical professionals. Unfortunately, this distrust would later lead to other epidemics, such as the influenza pandemic of 1918 and the coronavirus pandemic in 2020.
Why Did the Smallpox Vaccine Take So Long to End the Disease?
The smallpox vaccine was not immediately effective in ending the disease. In fact, it took many years for the vaccine to be perfected.
The first smallpox vaccine was developed in 1796 by Edward Jenner. However, it was not very effective and often caused side effects, such as fever and nausea. As a result, many people were reluctant to be vaccinated.
It wasn’t until the late 1800s that a more effective smallpox vaccine was developed. By this time, however, the smallpox epidemic had already begun to wane on its own.
It is thought that the disease simply mutated into a less deadly form. As a result, the vaccination campaign was not as successful as it could have been. Nevertheless, the smallpox vaccine did eventually help to eradicate the disease from the human population in the mid-20th Century.
There were several outbreaks of Smallpox throughout the years, with the most deadly one happening in 1857
The smallpox virus was one of the most feared diseases of the medieval world. Highly contagious and with no known cure, smallpox often resulted in a painful death.
The disease was responsible for numerous outbreaks throughout history, with the most deadly occurring in 1857. That year, smallpox killed over a million people worldwide.
The outbreak was so severe that it prompted the development of vaccines to protect against the disease. Today, smallpox is gone from the world, thanks to the vaccine. But the memory of this deadly disease still looms large in our collective history.
Today, there are no known cases of Smallpox anywhere in the world
In the early days of human history, smallpox was one of the most feared diseases. The virus caused high fevers and excruciating body aches, and it often resulted in disfiguring scars or death.
For centuries, smallpox ravaged communities all over the world, killing millions of people. However, in the late 18th century, a doctor named Edward Jenner discovered that vaccinating people with the smallpox virus could protect them from the disease.
This breakthrough led to a global vaccination campaign, and by 1979 smallpox had been completely eradicated. Today, there are no known cases of smallpox anywhere in the world. Thanks to vaccines, this deadly disease is now nothing more than a historical footnote.
About the Smallpox Hospital on Roosevelt Island in New York City
The Smallpox Hospital was a hospital on Roosevelt Island in New York City that was used to treat patients with smallpox. The hospital was built in 1856 and operated until 1896.
In 1858, a new wing was added to the hospital to accommodate an influx of patients during a smallpox epidemic. The hospital treated over two thousand patients during the epidemic.
The Smallpox Hospital is now a national historic site and one of the most popular tourist attractions on Roosevelt Island. Visitors can explore the hospital’s dark history, as well as its beautiful architecture.
