Staphylococcal enterotoxin B morbidity and incapacitation rates high; fatality not necessarily high.

• A. False
• B. Not sure
• C. True
• D. Unknown

Answer: (C)

Staphylococcal enterotoxin B causes a rapid, severe illness that leads to significant impairment and inability to function, which means high morbidity and incapacitation. Yet this condition is not typically fatal; with supportive care and treatment, most cases recover, so fatalities are not necessarily high. The toxin acts as a superantigen, triggering a strong immune response that drives the acute symptoms, but deaths are relatively uncommon compared to the level of illness produced. That combination—substantial illness and incapacitation but not typically high mortality—fits the statement, making it true.
