Informative Aspects Of Smallpox

Smallpox is a contagious, disfiguring and often deadly disease.

Samples of smallpox virus have been kept for research purposes. This has led to concerns that smallpox could someday be used as a biological warfare agent.

If an outbreak of smallpox were to occur today, it's likely that most doctors wouldn't realize what it was in its early stages, which would allow the disease to spread.
