In the 1300s a disease called the plague killed about 25 million people in Europe. The plague became known as the Black Death because of the black patches that appeared on a victim’s skin. Today people commonly use the word plague in two ways. They use it to refer to the disease itself. They also use it to mean a large outbreak of any dangerous disease. In the second case “plague” has the same meaning as the word epidemic.

There are two clinical forms of smallpox. Variola major is the severe and most common form of smallpox, with a more extensive rash and higher fever. There are four types of variola major smallpox: ordinary (the most frequent type, accounting for 90% or more of cases); modified (mild and occurring in previously vaccinated persons); flat; and hemorrhagic (both rare and very severe). Historically, variola major has an overall fatality rate of about 30%; however, flat and hemorrhagic smallpox usually are fatal. Variola minor is a less common presentation of smallpox, and a much less severe disease, with death rates historically of 1% or less.

Smallpox is spread by inhaling saliva or mucus droplets from an infected individual. After about 7 to 17 days, flulike symptoms begin; these include high fever, body aches, and fatigue. Within a few days a body rash develops that quickly evolves into pus-filled blisters, or pustules. By the second week the pustules form crusts, which dry out and turn into scabs. After a week or so the scabs fall off, leaving deep and often disfiguring scars. The mortality rate of smallpox is very high—up to 30 percent of its victims die from the disease. Those who do not die may suffer from complications of the disease, which include blindness, pneumonia, and kidney damage. No adequate treatment is available to fight the virus, though antibiotics may be prescribed to hinder secondary bacterial infections. The virus is remarkably stable and can exist in the environment and on bedding and clothing for extended periods of time.

Large outbreaks of smallpox have occurred throughout history, affecting individuals from all walks of life. Smallpox was responsible for the deaths of Queen Mary II of England, Emperor Joseph I of Austria, King Luis I of Spain, Tsar Peter II of Russia, Queen Ulrika Elenora of Sweden, and King Louis XV of France. Although the vaccine discovered by Jenner in 1796 was effective, it was not used consistently; by the 1950s, roughly 50 million cases of smallpox still occurred worldwide each year.

In the summer of 1793 Philadelphia was unusually hot, and dry, and congested. By June, a thousand refugees fleeing from revolution on the island of Santo Domingo had poured into the city. Their tales of slave revolt and of a fever epidemic engendered some support, and $15,000 dollars in relief money was quickly raised.

In August of 1793, several prominent Philadelphia physicians gathered to discuss a worrying trend: an increasing number of patients with symptoms of nausea, black vomit, lethargy, and yellow skin coloration. Among those present was Dr. Benjamin Rush, the city's most prominent doctor, signer of the Declaration of Independence, and supporter of the state and national constitutions. He quickly concluded that the culprit was the dreaded yellow fever.
