The smallpox vaccine is used to prevent smallpox infection caused by the variola virus. [10] It is the first vaccine to have been developed against a contagious disease. In 1796, British physician Edward Jenner demonstrated that an infection with the relatively mild cowpox virus conferred immunity against the deadly smallpox virus.
Smallpox was an infectious disease caused by variola virus (often called smallpox virus), which belongs to the genus Orthopoxvirus. [7] [11] 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, [10] making smallpox the only human disease to have been eradicated to date.
Boy with smallpox (1969). The last natural smallpox case was of Ali Maow Maalin, in Merca, Somalia, on 26 October 1977. [8] [9] Smallpox is the first disease, and so far the only infectious disease of humans, to be eradicated by deliberate intervention. [6]
The clearest description of smallpox from pre-modern times was given in the 9th century by the Persian physician, Muhammad ibn Zakariya ar-Razi, known in the West as "Rhazes", who was the first to differentiate smallpox from measles and chickenpox in his Kitab fi al-jadari wa-al-hasbah (The Book of Smallpox and Measles). [27]
Smallpox is more dangerous than variolation and cowpox less dangerous than variolation. Hypothesis: If target is infected with cowpox, then target is immune to smallpox. Test: If variolation after infection with cowpox fails to produce a smallpox infection, immunity to smallpox has been achieved. Consequence:
The FDA approved a drug that could be used to treat smallpox, a disease that was officially eradicated in 1980 -- but that doesn't mean it's gone for good.
(Reuters) -The U.S. Food and Drug Administration granted expanded approval to Emergent BioSolutions' smallpox vaccine for use in people at high risk of mpox infection. The FDA clearance, announced ...
The most common type of smallpox, ordinary, historically has devastated populations with a 30% death rate. The smallpox virus is transmittable through bodily fluids and materials contaminated with infected materials. Generally, face-to-face contact is required for an individual to contract smallpox as a result of an interaction with another human.
