Disease in Imperial Rome
During the imperial period of Rome, disease was a devastating aspect of life. As the borders of the empire continuously expanded and the population steadily grew, cities in the Roman Empire were exposed to a multitude of diseases. There were a variety of potential causes of these diseases present in the highly dense and quickly growing society's way of living. The sewage systems, the public bathing houses, and the diet of citizens in Imperial Rome all contributed to the spread of disease.
Environmental problems also played a part. For instance, deforestation led to a higher rate of transmission due to a chain reaction in the marshes from the rising water table that stemmed from deforestation. The diseases ranged in severity, some being catastrophic and others being not quite as deadly. One of the most prominent plagues during this period was the Antonine Plague. The people of Imperial Rome often had a very small amount of insight regarding the diseases that were overtaking their society. All of the information was known by a few prominent physicians that came up with the treatments, which were usually not very effective.

Hygiene
Roman sewage and aqueduct systems
The Roman Empire has garnered itself a mostly positive reputation for the complicated sewer systems that ran underneath many of its cities. Roman engineering brought water to the city from the Alban Hills using an aqueduct system implemented in 312 BC Although primitive forms of sewage systems have existed in Rome since pre-imperial times, these were mostly primitive drains that led to the nearby rivers and streams. Another source of water that proved to be dangerous was the Tiber River, which the Roman Army drank from, contributing to their vulnerability to many diseases. As the skills of engineers continued to grow, the complexity of the sewers did as well. For example, the Cloaca Maxima was one of the first complex and expansive sewer systems that ran under Rome. The aqueduct systems had an extremely complex design and for the most part succeeded in providing Romans with adequate amounts of relatively clean water for consumption and bathing.While the sewage systems of Imperial Rome may have been engineering marvels and set precedents, there were still major flaws in Roman sewer systems. The population of Rome and other cities in the empire steadily grew, increasing the strain on the waste systems. However, due to the public health laws concerning street disposal of public waste, most of the large outbreaks and public health crises cannot be directly attributed to the sewer systems of Rome. There were many other more serious factors that added to the catastrophe of the major public health crises of Imperial Rome. Since most sewer systems were privately owned, they were privately maintained, and in turn neglected. Instead, citizens would turn to their latrines; if they lived on anything but the ground floor they would even throw their excrement onto the street. This led to sewage being exposed to flies, dogs, and bacteria, all of which helped spread disease among Romans. Although it is unclear what specific diseases were caused by the toilets in Imperial Rome due to the lack of clarification in ancient texts during that time period, it is likely that a multitude of intestinal diseases would have been caused through the lack of sanitation. Some examples of waterborne diseases include dysentery, typhoid fever, and other types of diarrheas. Another infamous hazard to health was the lead piping used to transport water throughout the city. Modern science has proven the deleterious effects of lead, especially in regard to fertility. Some experts believe this may have been a leading factor in the population decline in the latter Imperial period. In fact, a study by Dr. Arthur Aufderheide of the University of Minnesota revealed that "Imperial age populations demonstrated up to ten-fold more bone lead than their predecessors or successors."
Alcohol consumption
Studies indicate that lead was very prominent in Roman beverages. This is mostly due to the lead-based storage containers that were popular during the time. Some scholars speculate that the levels of alcohol consumed on a daily basis were more to blame for the health ailments of the aristocrats of Rome, with the average consumption rate being approximately 3 bottles of wine a day. It is important to note that the practice of diluting wine was common as the source mentions, and that undiluted wine was considered barbaric. In fact, the Romans would typically mix one part wine to two parts of water. It was also common practice to warm wine or reduce its sweetness through the use of sea water.Litter pollution
The city of Rome also faced a major problem with street garbage and the build up of trash. Poets and satirists often made the Roman litter problem the subject of jokes and writings, with descriptions of trash being everywhere, including in Roman households and on the floor. The lack of sanitation on the streets and households of Rome contributed to disease and sickness. Trash items ranged from discarded household items to actual human waste, meaning contamination chances were very high. The Romans realized this was becoming a problem, and a series of laws and other measures were taken to limit garbage build up in the streets. Most of these measures were implemented in order to prevent pedestrian casualties from waste falling on them, however these measure also increased the public health by eliminating the waste from the immediate city. There is evidence to suggest that they allowed waste carriages to go throughout the city and collect waste during hours in which other modes of transportation were banned. This strategy did not completely solve the problem, as most of the waste was just moved outside the city limits meaning the risk for contamination and odor was still present.Bathing
Public and private bath houses were common in Rome during the Imperial period of Rome. Commonly referred to as Thermae, these bath houses varied widely, but most had similar bathing processes. Occupants would exercise, use a variety of saunas and cooling rooms, and sometimes swim in a pool. Even an imperial-version sauna was created for cleansing the body of toxins. The hours typically started at lunchtime and closed at dusk and was open to everyone, with only a small fee required to enter. Bath houses were typically located near the forum of Roman towns. Due to the high poverty rate in Rome, it was uncommon for the middle class citizens to own a private bath, according to journalist Jay Stuller. The heated bath water was not always chemically cleansed or filtered with chemicals such as chlorine, causing bacteria to thrive and spread. When Christianity came to Rome, it viewed the public nudity of the bathing system as debauchery and therefore it became frowned upon. While the bathing system may not have been pristine, abstaining from cleanliness altogether brought upon many more potentially fatal diseases, especially in infants.Environment
Population density
Rome's population was unprecedentedly large in the ancient world, reaching 1 million during the high point of the Empire. This was much larger than the other major cultures that co-existed and predated the Romans. Paired with the poor living conditions that many Romans experienced, the city was a perfect breeding ground for disease. In the poorer boroughs of Rome, tight living conditions and filth increased the spread of disease. The Antonine and Cyprian plagues were transmitted through touch, which only added to the severity of the plagues, especially in areas of poverty.Rome had an extremely high population, and remnants of buildings suggest the average living space was very small. Many people crammed into small spaces led to very high rates of infection for transmittable diseases. As the Antonine and Cyprian plagues were transmitted through touch, a dense population rate would contribute highly to their spread.
Deforestation
Deforestation of Rome's cities, particularly near the Tiber River, led to higher disease rates. The causality is as follows: deforestation lead to a rising water table, which increased marshes. This increased the larva in Rome, and in turn increased disease borne from blood-sucking insects. Mosquitoes and other vectors were carriers of various diseases, such as malaria.Air pollution
The air in Rome was undoubtedly polluted, with many sources remarking on the odours that could be found walking around the city. There were multiple sources of Rome's air pollution, open fires and human waste just being some of it. This degree of waste also attracted rodents and pests of all natures, only adding to the number of concerns for public health. It wasn't until the rule of Emperor Domitian that air pollution was attempted to be taken care of within the city. Laws were passed with the threat of fines and regulations that helped to attempt and clean the air.Diseases
In Imperial Rome, influenza, colds, and other ailments were just as apparent, if not more, compared to ailments in modern day Rome. Imperial Rome had many noteworthy diseases, ranging from sexually transmitted diseases to catastrophic plagues. This range indicates significant differences in the severity of the ailments present in Imperial Rome. As said by the Roman physician Galen, "This populous city, where daily ten thousand people can be discovered suffering from jaundice, and ten thousand from dropsy."Plagues
The Antonine Plague
The Antonine Plague was the first known pandemic impacting the Roman Empire. The plague, generally believed to be smallpox, was possibly brought by soldiers returning from the campaign in Western Asia, leading to catastrophic results for the Roman populace, whom had likely never been exposed to the disease before. The main symptoms included diarrhea, skin sores and irritations and sore throats. Symptoms lasted for around two weeks before they either died, or recovered and in turn developed immunity from further infection. Emperor Marcus Aurelius implemented several changes which suggest the dire status of the Empire. This included loosening the regulations for membership of higher councils in multiple important settlements throughout the empire, including Athens. Egypt was another region that saw catastrophic loss in the populations of their cities. This was demonstrated in the papyrus scripts documenting the loss in revenue from the massive decrease in population. The entire empire was facing hardship from the plague. Public building projects ceased in many of the provinces' major cities, including London. This all simultaneously happened while the empire faced attacks from the Sarmatians in the east. It is estimated that up to 15% of the Roman population was wiped out during the ten year plague, including Emperor Marcus Aurelius in 180 CE. It is widely believed that the plague was what is now known as smallpox. This can be determined largely due to the notes and commentary from famed Greek physician Galen. It is estimated that the Antonine Plague's impact on the Roman Empire was devastating and the effects lasted for centuries after the fact, some historians arguing that it permanently impaired the Empire and assisted in its downfall.The Antonine Plague was named after the emperor whose reign it originated in, Aurelius Antoninus, according to Louise Cilliers and Francis Retief. Historical sources suggest that Roman soldiers returning from campaign in Mesopotamia spread the disease, which lasted from 165 to 180 AD. Based on the written observations of fever, diarrhea, and boils by the Greek physician Galen, historians infer that smallpox caused the plague. Including substantial army deaths, the outbreaks decimated an estimated two thirds of the Roman population, killing roughly 2000 people per day.
