I am not sure if a cure for small pox has been found. This means that is no medicine that speeds up the process of curing small pox or reducing its permanent impact on the affected person. Once a person develops small pox, the recovery takes it's own natural course.
What has been found is a vaccination against small pox, that people from being affected by small pox. With the use of small pox vaccine, ii has been possible to wipe out almost completely cases of small pox from he face of the earth. Since the organism causing small pox thrive on small pox patients and are spread through infection, the elimination of small pox disease has almost eliminated small pox causing organism in the world.
However, it should be noted that specimen of small pox organisms may be maintained under controlled condition in some laboratories.
Small Pox has been an illness that we have been able to eradicate by the successful use of a vaccine developed to counter small pox in 1796. As a result of this, the last case of small pox was reported in 1977. Since then no cases of small pox have been reported and all virus samples of small pox on Earth have been destroyed except for two of them. One of these is kept at the Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia, and other at the State Research Center of Virology and Biotechnology in Koltsovo, Russia.
