Person to person: No insects or animals for this disease. Only contact with infectious material from a contageous person will pass this germ. Viral particles from sores inside the mouth or blisters on the skin are the source.

Inhaling the virus: Smallpox is highly contagious. In most cases, people get smallpox by inhaling droplets of saliva, which are full of virus, during face-to-face contact with an infected person.
