The deadly infectious disease smallpox was eradicated over 30 years ago by the World Health Organization, but the virus isn’t quite dead -- samples of variations of pathogens that cause smallpox are still held under high security at the CDC in the U.S. and in Russia.
The WHO is currently revisiting a topic that has divided scientists and epidemiologists for decades -- should the remaining samples be destroyed? The immunology and biosecurity communities are split on the issue.
Those who think the virus should be destroyed argue that in the wrong hands, smallpox poses an immense threat as a weapon of bioterror. Since smallpox was eradicated in 1980, vaccinations for the disease have stopped, leaving large populations vulnerable. Those who want the samples preserved argue that more research could help develop increasingly effective treatments and vaccines, and could aid in eradicating any future strains of smallpox that may emerge.
Should the smallpox virus be preserved for research, or is it too dangerous? How should the WHO decide the best course of action?
