Depending on how severe the infection at exposure is, patients usually develop symptoms at around 7 years after the entry of the virus.
Symptoms can be in the form of any single or multiple system involvement. Infection occurs which either does not respond to routine treatment because of resistant strains or, if it responds, it does so after a long time only to recur. Such repeated infections debilitate the body leading to death. The drugs too, often produce rare reactions in AIDS patients not commonly seen otherwise.
