Smallpox, caused by variola major, was eradicated globally but remaining virus stockpiles pose a bioterrorism risk. Genetic engineering could potentially restore smallpox

Area of Science:

  • Infectious Diseases
  • Virology
  • Public Health

Background:

  • Variola major, the virus causing smallpox, historically represented a significant global health threat.
  • Smallpox was successfully eradicated worldwide through extensive immunization campaigns.
  • Humans are the sole known reservoir for the variola major virus.

Purpose of the Study:

  • To highlight the continued risk posed by remaining variola major virus stockpiles.
  • To discuss the potential threat of genetically engineered variola major.
  • To emphasize the importance of vigilance regarding smallpox virus containment.

Main Methods:

  • Review of historical smallpox eradication efforts.
  • Analysis of current variola major virus containment status.

Related Experiment Videos

  • Discussion of potential biosecurity risks associated with viral stockpiles.

    • Main Results:

    • Naturally occurring smallpox has been eradicated globally.
    • Stockpiles of variola major virus exist in the United States and the former Soviet Union.
    • The possibility of unknown or unreported variola major stocks remains a concern.

    Conclusions:

    • Despite eradication, variola major virus stockpiles present a potential bioterrorism threat.
    • Genetic engineering could theoretically re-create a virulent smallpox strain.
    • Continued monitoring and stringent control of remaining variola virus are crucial for global security.
