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.
Smallpox is the first disease, and so far the only infectious disease of humans, to be eradicated by deliberate intervention. [6] It became the first disease for which there was an effective vaccine in 1798 when Edward Jenner showed the protective effect of inoculation (vaccination) of humans with material from cowpox lesions. [10]
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.
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.
The words come from various (spotted) or varus (pimple). In England, this disease was first known as the "pox" or the "red plague". Smallpox settles itself in small blood vessels of the skin and in the mouth and throat. The symptoms of smallpox are rash on the skin and blisters filled with raised liquid. [citation needed]
Smallpox was an infectious disease caused by two strains of virus, Variola major and V. minor. V. minor was the rarer of the two strains, and causes a much less severe disease (sometimes called alastrim), with a fatality rate of around 1%. No treatment is available, and the only protection is vaccination. The virus is usually transmitted by ...
This committee was an action taken towards eradicating smallpox in Mexico through campaigning through systematic and routine work regarding the vaccine. They mainly pursued smaller and rural communities that had been harder or had less resources to combat the disease. [23] Smallpox was officially declared eradicated from Mexico in 1951.
A few days after Mumdžić's death, 140 smallpox cases erupted across Kosovo province. [10] On 16 March, the smallpox virus was isolated in Belgrade by Ana Gligić, the head of the national smallpox laboratory, which was followed by strict measures that prevented the spread of the disease in the city and thus a major disaster.
