Smallpox virus

In 1993, the last research samples of the smallpox virus were scheduled to be destroyed. Smallpox was the world's most dreaded plagues until 1977, when it was declared eradicated. However, some scientists who wanted to continue research on the virus stopped the destruction plan. The remaining frozen samples are in Moscow, Russia, and the Centers for Disease Control and Prevention, Atlanta, U.S., ready to make vaccine should it ever again be necessary. The virus is extremely stable and has not changed in hundreds or even thousands of years. Smallpox (variola) is caused by a poxvirus and was spread from person to person by contact with skin lesions or via the respiratory tract. Its name comes from the pockmarks on the skin that it caused.
