The Massachusetts smallpox epidemic or colonial epidemic was a smallpox outbreak that hit Massachusetts in 1633. [1] Smallpox outbreaks were not confined to 1633 however, and occurred nearly every ten years. [2] Smallpox was caused by two different types of variola viruses: variola major and variola minor. [3] The disease was hypothesized to be transmitted due to an increase in the immigration of European settlers to the region who brought Old World smallpox aboard their ships. [4]
Smallpox, is known under scientific nomenclature as Variola virus. There are two strains of Variola virus, Variola major and Variola minor. The Variola major strain is the most common and is the strain that most likely wiped out indigenous and colonist populations during the 1633 epidemic. Variola major’s weaker sister, Variola minor, was less common and only results in approximately less than 1% of deaths related to smallpox. [5] Smallpox is thought to be ancient, and it is not native to North America. [6]
The virus is spread by airborne salivae, like from a cough or saliva on a bed sheet, and can only be spread from human to human. The first stage of infection is the incubation period. The incubation period is the preliminary stage of infection where there is no knowledge of someone having smallpox, there are no physical manifestations of illness during this period. The length of the incubation period is typically 10-14 days. Following the incubation period, initial symptoms start to appear, such as a fever. Within the next few days, they start to form a rash on their skin, and tongue, and can even be found in their mouth and throat. The rash sores then form into pustules which eventually scab over and fall off. Once all of the scabs have fallen off, the person is no longer contagious. [7]
Smallpox was not present in indigenous populations before the arrival of European settlers to the New World. Settlers likely brought smallpox and introduced the disease to the New World when coming on their ships. [4] Indigenous populations had no previous encounters with smallpox, so the disease was considered an unexpected and severe killer of their peoples compared to the predominant nature and consistent presence of the disease within Europe and Asia. [8]
There are no statistics on the number of cases of smallpox in the 1633 epidemic. Though there are rough estimates that after Europeans arrived to the New World, approximately 20 million people died. [4]
Europeans brought smallpox to North America when they first began colonizing. Most Europeans were at least partially immune to the disease due to high levels of exposure from living conditions which were often in close contact with Iivestock and in areas with large human populations. [9] However, 20 settlers on the Mayflower were infected including their only physician Samuel Fuller.
While the European settlers remained mostly unaffected by smallpox in 1630, they witnessed their Native American neighbors fall victim to it rapidly. A New England colonist in 1630 said the Native Americans "fell down so generally of this disease as they were in the end not able to help one another, not to make a fire, nor to fetch a little water to drink, nor any to bury the dead...". Yet despite the destruction wrought by smallpox, it was seen as a gift from God by some Puritans. This included Increase Mather, a clergyman and one of Harvard College's first presidents, who stated that the smallpox epidemic was God's solution to the Native American and Puritan land disputes.
Some Christian settlers in Boston thought that they caught smallpox from being religiously sinful. [10]
Nearby Native Americans were not immune to smallpox and by 1618, a year after the first epidemic swept through Massachusetts, more than two-thirds of the Massachusetts Native Americans including the Mohawks, native people in the Lake Ontario area and the Iroquois were killed from infection.[ citation needed ] The epidemic continued and by 1633, smallpox infected entire tribes and left the people unable to care for each other or bury their dead. [1] There is a hypothesis that Native populations might have had a higher concentration of deaths compared to European settlers due to "protein-calorie malnutrition" from 1500-1800 in the New World. The symptoms of protein-calorie malnutrition influence the immune system and also persisting weight loss, anemia, slow wound healing, and in some cases muscular dystrophy. This hypothesis is supported by skeletal evidence of Native populations. [8]
The indigenous tribe most populous in the Massachusetts Bay region during the 17th century was the Wampanoag tribe. The Wampanoag people were the first indigenous population to have contact with the European settlers arriving in Plymouth off the Mayflower. The estimates of the original Wampanoag population were approximately 12,000, though after the introduction of colonization and disease their populations were decimated to a mere 400. Due to the lack of immunity within indigenous communities, the disease ravaged their populations and caused a direct demographic shift on the populations of early American colonies. Other factors that contributed to the decimation of indigenous populations would be the dispersed nature of indigenous tribes. [11] Due to the presence of English colonists spreading disease such as smallpox, there was a definitive demographic shift of the region from a dominant indigenous Wampanoag population to a growing English settler population. [12]
European settlers believed that the smallpox disease was the result of their religious sinfulness. As a means of treating their conditions, people began to pray to their Christian God and participate in fasting as well as repenting for their sins. Some individuals also responded by leaving the area to avoid the disease. [10]
Variolation was known as inoculation in Massachusetts during this time period. This is a procedure that can be performed a few different ways. They all included taking scabs or pus from someone who had natural smallpox. People would then take the scab or pus and inject it into their skin, or rub the matter on themselves. This would allow them to have a mild form of smallpox, which had a low mortality rate. Once someone has been infected with smallpox, they would never get the virus again. This operation allowed people to be immune for the rest of their lives. [13] This is what a man named Cotton Mather proposed during the Boston smallpox epidemic of 1721. He sought out many doctors to perform this procedure, but the only one who was willing to try was Dr. Zabdiel Boylston. This doctor had a history of performing risky procedures, and when it was time to try inoculation he tested his hypothesis on his six-year-old son. [10] The smallpox inoculation was deemed successful after much deliberation between government officials and other doctors. This procedure was then spread throughout the city in hopes to get the virus under control. [14]
After the events of the 1633 Massachusetts smallpox epidemic there were subsequent outbreaks of smallpox in the region. Most notably in 1721, there was a significant outbreak of smallpox in Massachusetts. [10] According to a historical account in 1884 of the 1721 smallpox outbreak, more than one sixth of people would die from smallpox naturally if not treated by inoculation. Dr. Boylston was threatened to be hanged by townsfolk because they believed that the smallpox disease was an act of God and the doctor should not interfere. In 1722, there was a religious sermon that compared Dr. Boylston to Job in the Bible by saying, "the Devil was the first inoculator and Job his first patient." [15] The last smallpox case in Massachusetts, specifically Boston, was in 1932. [16]
Cotton Mather was a Puritan clergyman and author in colonial New England, who wrote extensively on theological, historical, and scientific subjects. After being educated at Harvard College, he joined his father Increase as minister of the Congregationalist Old North Meeting House in Boston, Massachusetts, where he preached for the rest of his life. He has been referred to as the "first American Evangelical".
Cowpox is an infectious disease caused by the cowpox virus (CPXV). It presents with large blisters in the skin, a fever and swollen glands, historically typically following contact with an infected cow, though in the last several decades more often from infected cats. The hands and face are most frequently affected and the spots are generally very painful.
The Wampanoag, also rendered Wôpanâak, are a Native American people of the Northeastern Woodlands currently based in southeastern Massachusetts and formerly parts of eastern Rhode Island. Their historical territory includes the islands of Martha's Vineyard and Nantucket.
The first European contact in 1492 started an influx of communicable diseases into the Caribbean. Diseases originating in the Old World (Afro-Eurasia) came to the New World for the first time, resulting in demographic and sociopolitical changes due to the Columbian Exchange from the late 15th century onwards. The Indigenous peoples of the Americas had little immunity to the predominantly Old World diseases, resulting in significant loss of life and contributing to their enslavement and exploitation perpetrated by the European colonists. Waves of enslaved Africans were brought to replace the dwindling Indigenous populations, solidifying the position of disease in triangular trade.
The Massachusett were a Native American tribe from the region in and around present-day Greater Boston in the Commonwealth of Massachusetts. The name comes from the Massachusett language term for "At the Great Hill," referring to the Blue Hills overlooking Boston Harbor from the south.
The New World of the Western Hemisphere was devastated by the 1775–1782 North American smallpox epidemic. Estimates based on remnant settlements say at least 130,000 people were estimated to have died in the epidemic that started in 1775.
Artificial induction of immunity is immunization achieved by human efforts in preventive healthcare, as opposed to natural immunity as produced by organisms' immune systems. It makes people immune to specific diseases by means other than waiting for them to catch the disease. The purpose is to reduce the risk of death and suffering, that is, the disease burden, even when eradication of the disease is not possible. Vaccination is the chief type of such immunization, greatly reducing the burden of vaccine-preventable diseases.
Globalization, the flow of information, goods, capital, and people across political and geographic boundaries, allows infectious diseases to rapidly spread around the world, while also allowing the alleviation of factors such as hunger and poverty, which are key determinants of global health. The spread of diseases across wide geographic scales has increased through history. Early diseases that spread from Asia to Europe were bubonic plague, influenza of various types, and similar infectious diseases.
The 1837 Great Plains smallpox epidemic spanned 1836 through 1840 but reached its height after the spring of 1837, when an American Fur Company steamboat, the SS St. Peter, carried infected people and supplies up the Missouri River in the Midwestern United States. The disease spread rapidly to indigenous populations with no natural immunity, causing widespread illness and death across the Great Plains, especially in the Upper Missouri River watershed. More than 17,000 Indigenous people died along the Missouri River alone, with some bands becoming nearly extinct.
Smallpox was an infectious disease caused by variola virus, which belongs to the genus Orthopoxvirus. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making smallpox the only human disease to have been eradicated to date.
The Patuxet were a Native American band of the Wampanoag tribal confederation. They lived primarily in and around modern-day Plymouth, Massachusetts, and were among the first Native Americans encountered by European settlers in the region in the early 17th century. Most of the population subsequently died of epidemic infectious diseases. The last of the Patuxet – an individual named Tisquantum, who played an important role in the survival of the Pilgrim colony at Plymouth – died in 1622.
Disease in colonial America that afflicted the early immigrant settlers was a dangerous threat to life. Some of the diseases were new and treatments were ineffective. Malaria was deadly to many new arrivals, especially in the Southern colonies. Of newly arrived able-bodied young men, over one-fourth of the Anglican missionaries died within five years of their arrival in the Carolinas. Mortality was high for infants and small children, especially for diphtheria, smallpox, yellow fever, and malaria. Most sick people turned to local healers, and used folk remedies. Others relied upon the minister-physicians, barber-surgeons, apothecaries, midwives, and ministers; a few used colonial physicians trained either in Britain, or an apprenticeship in the colonies. One common treatment was blood letting. The method was crude due to a lack of knowledge about infection and disease among medical practitioners. There was little government control, regulation of medical care, or attention to public health. By the 18th century, Colonial physicians, following the models in England and Scotland, introduced modern medicine to the cities in the 18th century, and made some advances in vaccination, pathology, anatomy and pharmacology.
The history of smallpox extends into pre-history. Genetic evidence suggests that the smallpox virus emerged 3,000 to 4,000 years ago. Prior to that, similar ancestral viruses circulated, but possibly only in other mammals, and possibly with different symptoms. Only a few written reports dating from about 500 AD to 1000 AD are considered reliable historical descriptions of smallpox, so understanding of the disease prior to that has relied on genetics and archaeology. However, during the 2nd millennium AD, especially starting in the 16th century, reliable written reports become more common. The earliest physical evidence of smallpox is found in the Egyptian mummies of people who died some 3,000 years ago. Smallpox has had a major impact on world history, not least because indigenous populations of regions where smallpox was non-native, such as the Americas and Australia, were rapidly and greatly reduced by smallpox during periods of initial foreign contact, which helped pave the way for conquest and colonization. During the 18th century the disease killed an estimated 400,000 Europeans each year, including five reigning monarchs, and was responsible for a third of all blindness. Between 20 and 60% of all those infected—and over 80% of infected children—died from the disease.
Although a variety of infectious diseases existed in the Americas in pre-Columbian times, the limited size of the populations, smaller number of domesticated animals with zoonotic diseases, and limited interactions between those populations hampered the transmission of communicable diseases. One notable infectious disease that may be of American origin is syphilis. Aside from that, most of the major infectious diseases known today originated in the Old World. The American era of limited infectious disease ended with the arrival of Europeans in the Americas and the Columbian exchange of microorganisms, including those that cause human diseases. Afro-Eurasian infections and epidemics had major effects on Native American life in the colonial period and nineteenth century, especially.
In epidemiology, a virgin soil epidemic is an epidemic in which populations that previously were in isolation from a pathogen are immunologically unprepared upon contact with the novel pathogen. Virgin soil epidemics have occurred with European settlement, particularly when European explorers and colonists brought diseases to lands they settled in the Americas, Australia and Pacific Islands.
Variolation was the method of inoculation first used to immunize individuals against smallpox (Variola) with material taken from a patient or a recently variolated individual, in the hope that a mild, but protective, infection would result. Only 1–2% of those variolated died from the intentional infection compared to 30% who contracted smallpox naturally. Variolation is no longer used today. It was replaced by the smallpox vaccine, a safer alternative. This in turn led to the development of the many vaccines now available against other diseases.
Inoculation is the act of implanting a pathogen or other microbe or virus into a person or other organism. It is a method of artificially inducing immunity against various infectious diseases. The term "inoculation" is also used more generally to refer to intentionally depositing microbes into any growth medium, as into a Petri dish used to culture the microbe, or into food ingredients for making cultured foods such as yoghurt and fermented beverages such as beer and wine. This article is primarily about the use of inoculation for producing immunity against infection. Inoculation has been used to eradicate smallpox and to markedly reduce other infectious diseases such as polio. Although the terms "inoculation", "vaccination", and "immunization" are often used interchangeably, there are important differences. Inoculation is the act of implanting a pathogen or microbe into a person or other recipient; vaccination is the act of implanting or giving someone a vaccine specifically; and immunization is the development of disease resistance that results from the immune system's response to a vaccine or natural infection.
Onesimus was an African man who was instrumental in the mitigation of the impact of a smallpox outbreak in Boston, Massachusetts. His birth name is unknown. He was enslaved and, in 1706, was given to the New England Puritan minister Cotton Mather, who renamed him. Onesimus introduced Mather to the principle and procedure of the variolation method of inoculation to prevent the disease, which laid the foundation for the development of vaccines. After a smallpox outbreak began in Boston in 1721, Mather used this knowledge to advocate for inoculation in the population. This practice eventually spread to other colonies. In a 2016 Boston magazine survey, Onesimus was declared one of the "Best Bostonians of All Time".
In 1721, Boston experienced its worst outbreak of smallpox. 5,759 people out of around 10,600 in Boston were infected and 844 were recorded to have died between April 1721 and February 1722. The outbreak motivated Puritan minister Cotton Mather and physician Zabdiel Boylston to variolate hundreds of Bostonians as part of the Thirteen Colonies' earliest experiment with public inoculation. Their efforts would inspire further research for immunizing people from smallpox, placing the Massachusetts Bay Colony at the epicenter of the Colonies' first inoculation debate and changing Western society's medical treatment of the disease. The outbreak also altered social and religious public discourse about disease, as Boston's newspapers published various pamphlets opposing and supporting the inoculation efforts.
European colonisation of Australia was accompanied by epidemic diseases to which the original inhabitants had little resistance. Colds, influenzas, tuberculosis (TB), and measles were major killers. Such diseases devastated Aboriginal populations, weakened their cultures, and often left them in no position to resist the newcomers. Within perhaps as little as six months of the arrival of the First Fleet, venereal disease was already a serious problem for local Aboriginal peoples; but the first disease to produce a major fall in the Aboriginal population around Sydney was the 1789 outbreak, some 16 months after the Fleet arrived, of what Governor Phillip and others referred to as "smallpox". Watkin Tench, a captain in the Marines, wrote that,
pustules, similar to those occasioned in the smallpox, were thickly spread on the bodies; but how a disease to which our former observations had led us to suppose them strangers could at once have introduced itself, and spread so widely, seemed inexplicable.
