简要总结
The objective of this clinical trial is to determine whether long-term oral dosage of ribavirin delays development of symptomatic HIV disease in HIV antibody positive subjects who are completely asymptomatic (CDC classification group II), who have only the lymphadenopathy syndrome (CDC classification group III), or who have clinical symptoms but not severe HIV disease as defined by CDC classification, and whether the dosage regimen is safe and tolerable in these subjects.
