Is smallpox still around today?

Currently, there is no evidence of naturally occurring smallpox transmission anywhere in the world. Although a worldwide immunization program eradicated smallpox disease decades ago, small quantities of smallpox virus officially still exist in two research laboratories in Atlanta, Georgia, and in Russia.
A.

When was the smallpox vaccine discontinued in the United States?

Because of vaccination programs and quarantine regulations, the risk of importation of smallpox into the United States was reduced by the 1960s. As a result, routine vaccinia vaccination was discontinued in 1971 (2).

Although smallpox is a vaccine preventable disease, immunization programs were stopped in Canada in 1972 for infants, in 1977 for health care workers and in 1988 for Canadian Forces. Smallpox is caused by the variola virus.
  • Is smallpox eradicated from the world?

    Smallpox is unique in that it's the only infectious disease to have ever been eradicated. The disease is caused by the variola virus, which is closely related to the cowpox virus. Until its eradication in 1979, smallpox was "one of the world's most feared diseases," and rightly so.
  • What is the cause of small pox?

    The variola virus causes it. There are two forms of the virus. The more dangerous form, variola major, led to smallpox disease that killed about 30% of people who were infected. Variola minor caused a less deadly type that killed about 1% of those who got it.
  • What are the side effects of the smallpox vaccine?

    Variola (the virus that causes smallpox) is a member of the orthopoxvirus genus, which also includes viruses that cause cowpox, monkeypox, orf, and molluscum contagiosum. Poxviruses are the largest animal viruses, visible with a light microscope. They are larger than some bacteria and contain double-stranded DNA.
  • Is chicken pox and smallpox the same thing?

    Thanks to the success of vaccination, the last natural outbreak of smallpox in the United States occurred in 1949. In 1980, the World Health Assembly declared smallpox eradicated (eliminated), and no cases of naturally occurring smallpox have happened since.
