What is the prognosis for Staph infections?

The prognosis or outcome of Staph infections depends upon the type of infection that is present as well as other factors such as the extent to which the infection has spread and the underlying medical condition of the patient. Skin infections and superficial infections, in general, are readily cured with antibiotics. In rare cases, these infections may spread and cause complications, including sepsis (spread of infection to the bloodstream). It is important to remember that even after taking antibiotics for a Staph infection you can still develop a repeat infection.

Widespread infections such as sepsis have a more guarded prognosis; mortality (death) rates range from 20%-40% in cases of Staph aureus infection of the bloodstream. Before antibiotics were available, about 80% of people with Staph aureus sepsis died from complications of the condition. People with suppressed immune systems (those taking immune-suppressing medications or with immune deficiencies) are at increased risk for developing more serious infections.

Staphylococcal food poisoning typically resolves on its own without long-term complications.
