What CD4 count range characterizes HIV stage II?

Explanation:
CD4 cell count is used to grade how much the immune system is affected by HIV. When the count stays near normal, the infection is considered Stage I, meaning immune function is relatively preserved. If the count drops to a mid-range level, the immune system is moderately weakened, which is Stage II. At this stage there’s a noticeable risk of opportunistic infections and other complications, but it isn’t as severe as AIDS. Very low CD4 counts, or the presence of AIDS-defining illnesses, indicate Stage III. So Stage II represents the middle level of immune suppression—not normal, not severely depleted, but clearly reduced enough to raise the risk of infections compared with Stage I.
