Acute hemorrhagic conjunctivitis.

Acute hemorrhagic conjunctivitis, an infection caused by enterovirus 70 and a variant of coxsackievirus A24, is characterized by the rapid onset of severely painful conjunctivitis and subconjunctival hemorrhage. The condition is usually benign and resolves in five to seven days; however, a polio-like paralysis (radiculomyelitis) develops in approximately one in 10,000 patients infected with enterovirus 70. No treatment is available. Information about acute hemorrhagic conjunctivitis should be provided to patients and the community in order to prevent undue alarm, discourage home remedies and control the spread of this highly contagious disease.
