Antiviral Drugs. In July 2018, the FDA approved tecovirimat (TPOXX) for treatment of smallpox. In laboratory tests, tecovirimat has been shown to stop the growth of the virus that causes smallpox and to be effective in treating animals that had diseases similar to smallpox.

Smallpox Vaccine
Smallpox can be prevented by the smallpox vaccine, also called vaccinia virus vaccine. The vaccine is made from a virus called vaccinia, which is a poxvirus similar to smallpox, but less harmful. There are two licensed smallpox vaccines in the United States and one investigational vaccine that may be used in a smallpox emergency.

What was the purpose of the British use of smallpox?
The British used smallpox as a biological warfare agent at the Siege of Fort Pitt during the French and Indian Wars (1754–1763) against France and its Native American allies. British officers, including the top British commanding generals, ordered, sanctioned, paid for and conducted the use of smallpox against the Native Americans. As described by historians, "there is no doubt that British military authorities approved of attempts to spread smallpox among the enemy", and "it was deliberate British policy to infect the Indians with smallpox". On 24 June 1763, William Trent, a local trader and commander of the Fort Pitt militia, wrote, "Out of our regard for them, we gave them two Blankets and an Handkerchief out of the Small Pox Hospital. I hope it will have the desired effect." The effectiveness of this effort to broadcast the disease is unknown. There are also accounts that smallpox was used as a weapon during the American Revolutionary War (1775–1783).
What is smallpox caused by?
Smallpox was an infectious disease caused by one of two virus variants, Variola major and Variola minor. The agent of variola virus (VARV) 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.
What are the symptoms of smallpox?
A child showing rash due to ordinary-type smallpox (variola major) The initial symptoms were similar to other viral diseases that are still extant, such as influenza and the common cold: fever of at least 38.3 °C (101 °F), muscle pain, malaise, headache and fatigue.
How long does it take for a smallpox rash to develop?
Smallpox virus tended to attack skin cells, causing the characteristic pimples, or macules, associated with the disease. A rash developed on the skin 24 to 48 hours after lesions on the mucous membranes appeared.
What is the prodromal phase of smallpox?
The early or fulminant form of hemorrhagic smallpox (referred to as purpura variolosa) begins with a prodromal phase characterized by a high fever, severe headache, and abdominal pain. The skin becomes dusky and erythematous, and this is rapidly followed by the development of petechiae and bleeding in the skin, conjunctiva and mucous membranes. Autopsy reveals petechiae and bleeding in the spleen, kidney, serous membranes, skeletal muscles, pericardium, liver, gonads and bladder. Death often occurs suddenly between the fifth and seventh days of illness, when only a few insignificant skin lesions are present. Some people survive a few days longer, during which time the skin detaches and fluid accumulates under it, rupturing at the slightest injury. Historically, this condition was frequently misdiagnosed, with the correct diagnosis made only at autopsy. It is more likely to occur in pregnant women than in the general population (approximately 16% of cases in unvaccinated pregnant women were early hemorrhagic smallpox, versus roughly 1% in nonpregnant women and adult males). The case fatality rate of early hemorrhagic smallpox approaches 100%.
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.
Is there a cure for smallpox?

Smallpox ravaged human populations for thousands of years, but in 1796 Edward Jenner discovered that exposure to cowpox lesions could provide immunity to smallpox. This led to the creation of the first vaccine for a disease.
Does S. purpurea inhibit replication?
The team made extracts of S. purpureaand found that it was highly effective at inhibiting the replication of the virus in rabbit kidney cells. They then looked at the replication cycle of the virus and found that the herb inhibits mRNA synthesis, halting production of proteins vital for replication.
