Most people who get smallpox survive. However, there are a few rare varieties of smallpox that are almost always fatal. These more severe forms of smallpox most commonly affect pregnant women and people with impaired immune systems.
People who recover from smallpox usually have severe scars, especially on the face, arms and legs. In some cases, smallpox may cause blindness.
