Diagnostic basis

There is often a history of purulent conjunctivitis. After the conjunctivitis subsides, there is a sudden onset of high fever, vomiting, abdominal pain, diarrhea, purpuric rash, and shock. The diagnosis is confirmed by positive bacterial cultures of blood, cerebrospinal fluid, and purpura. However, positive bacterial culture of eye secretion and nasopharynx requires bacterial identification test to confirm the diagnosis.
