− | |||
− | An illness with the following clinical manifestations: |

− | * '''Fever:''' temperature greater than or equal to 102.0°F (greater than or equal to 38.9°C) |
||
− | * '''Rash:''' diffuse macular erythroderma |

− | * '''Desquamation:''' 1-2 weeks after onset of rash |
||
− | * '''Hypotension:''' systolic blood pressure less than or equal to 90 mm Hg for adults or less than fifth percentile by age for children aged less than 16 years |
||
− | * '''Multisystem involvement''' (three or more of the following organ systems): |
||
− | ** '''Gastrointestinal:''' vomiting or diarrhea at onset of illness |
||
− | ** '''Muscular:''' severe myalgia or creatine phosphokinase level at least twice the upper limit of normal |
||
− | ** '''Mucous membrane:''' vaginal, oropharyngeal, or conjunctival hyperemia |
||
− | ** '''Renal:''' blood urea nitrogen or creatinine at least twice the upper limit of normal for laboratory or urinary sediment with pyuria (greater than or equal to 5 leukocytes per high-power field) in the absence of urinary tract infection |
||
− | ** '''Hepatic:''' total bilirubin, alanine aminotransferase enzyme, or asparate aminotransferase enzyme levels at least twice the upper limit of normal for laboratory |
||
− | ** '''Hematologic:''' platelets less than 100,000/mm3 |

− | * Confirmed: A case which meets the laboratory criteria and in which all five of the clinical criteria described above are present, including desquamation, unless the patient dies before desquamation occurs |
