<unk>  virus <unk> V or VV) is a large, complex, enveloped virus belonging to the poxvirus family. It has a linear, double-stranded DNA genome approximately 190 kbp in length, and which encodes for approximately 250 genes. The dimensions of the virion are roughly 360 × 270 × 250 nm.<unk>  virus is well-known for its role as a<unk> cine that eradicated the smallpox disease, making it the first human disease to be successfully eradicated by mankind. This endeavour was carried out by the World Health Organization under the Smallpox Eradication Program. Post eradication of smallpox, scientists study<unk>  virus to use as a tool for delivering genes into biological tissues (gene therapy and genetic engineering). Moreover, due to recent concerns about smallpox resurfacing as a possible agent for bioterrorism, scientists have renewed their interests in studying<unk>  virus.
