Clinical Findings and Results of Treatment in an Outbreak of Acute Hemorrhagic Conjunctivitis in Southern Florida

An epidemic of acute hemorrhagic conjunctivitis in Miami, Florida, involved approximately 800 documented cases and more than 2,500 suspected cases. This epidemic was caused by an enterovirus 70 infection affecting primarily young black people residing within a high-risk area. Acute hemorrhagic conjunctivitis is characterized by the rapid onset of swollen eyelids, foreign-body sensation, burning, watery discharge, and, usually, bilateral ocular involvement. Signs include distinctive bulbar conjunctival hemorrhages and a follicular conjunctival reaction with only mild and infrequent corneal involvement. This infection is short in duration, self-limited, and free of significant ocular sequelae. Symptomatic treatment appears to be as effective as various topical medical regimens for relief of symptoms. Secondary bacterial infections (occurring in individuals who used urine as an eyewash) and one case of a transient acute Bell's palsy were the only complications associated with this acute hemorrhagic conjunctivitis epidemic
