Medication
Treatment of smallpox patients generally involves supportive care. Vaccination with replication-competent smallpox vaccines (i.e., ACAM2000 and APSV) can prevent or lessen the severity of disease if given within 2 to 3 days of the initial exposure. They may decrease symptoms if given within the first week of exposure.

When was smallpox first inoculated?
The first clear reference to smallpox inoculation was made by the Chinese author Wan Quan (1499–1582) in his Dòuzhěn xīnfǎ (痘疹心法) published in 1549, with earliest hints of the practice in China during the 10th century. In China, powdered smallpox scabs were blown up the noses of the healthy. People would then develop a mild case of the disease and from then on were immune to it. The technique did have a 0.5–2.0% mortality rate, but that was considerably less than the 20–30% mortality rate of the disease itself. Two reports on the Chinese practice of inoculation were received by the Royal Society in London in 1700; one by Dr. Martin Lister who received a report by an employee of the East India Company stationed in China and another by Clopton Havers. Voltaire (1742) reports that the Chinese had practiced smallpox inoculation "these hundred years". Variolation had also been witnessed in Turkey by Lady Mary Wortley Montagu, who later introduced it in the UK.
How long ago did smallpox first appear?
The date of the appearance of smallpox is not settled. It most probably evolved from a terrestrial African rodent virus between 68,000 and 16,000 years ago . The wide range of dates is due to the different records used to calibrate the molecular clock. One clade was the Variola major strains (the more clinically severe form of smallpox) which spread from Asia between 400 and 1,600 years ago. A second clade included both Alastrim minor (a phenotypically mild smallpox) described from the American continents and isolates from West Africa which diverged from an ancestral strain between 1,400 and 6,300 years before present. This clade further diverged into two subclades at least 800 years ago.
What is the name of the disease that causes black pox?
Hemorrhagic smallpox is a severe form accompanied by extensive bleeding into the skin, mucous membranes, gastrointestinal tract, and viscera. This form develops in approximately 2 percent of infections and occurs mostly in adults. Pustules do not typically form in hemorrhagic smallpox. Instead, bleeding occurs under the skin, making it look charred and black, hence this form of the disease is also referred to as variola nigra or "black pox." Hemorrhagic smallpox has very rarely been caused by Variola minor. While bleeding may occur in mild cases and not affect outcomes, hemorrhagic smallpox is typically fatal.

What is tecovirimat used for?
Tecovirimat has been used in the treatment of severe adverse events to vaccinia vaccination ; however, there are limited efficacy data in humans. Tecovirimat’s effectiveness against smallpox was established with in vitro studies using related orthopoxviruses as well as variola. Efficacy of tecovirimat treatment has also been demonstrated within multiple animal model studies measuring survival in animals infected with either variola virus or other closely related orthopoxviruses. Furthermore, treatment with tecovirimat minimized signs of morbidity as well as protected from mortality within prairie dogs challenged with monkeypox virus. The safety of tecovirimat was evaluated in 359 healthy human volunteers.
