“…Diagnosis for TSS is usually based on the United States Centers for Disease Control and Prevention (CDC) clinical criteria which include fever, hypotension, diffuse erythroderma, and involvement of at least three organ systems, in addition to negative cultures for alternative pathogens and negative serologic tests for other conditions [ 5 ].
