Cardiac involvement is associated with a very a poor prognosis, particularly AV and left bundle-branch blocks (mortality rate 60-90%).

Bacteremic disease carries a mortality rate of 30-40%.

High mortality rate is seen with invasive disease.

High mortality rates are seen in individuals younger than 5 years and in those older than 40 years.
