Smallpox virus may be transmitted from contaminated surfaces or aerosolized particles. It is capable of inducing harm by evading the host's immune system and replicating inside host's cells. The virus may cause 3 forms of the disease: 1) ordinary; 2) flat-type; or 3) hemorrhagic smallpox. It infects different cells of the body, being known by it's propensity to cause characteristic pock like lesions on the skin.
