DOC, WHAT WOULD BE THE MAJOR DIFFERENCES BETWEEN THESE THREE STRAINS OF HIV IN REGARDS TO SYMPTOMS, METHODS OF CONTROL, ETC. THANKS FOR YOUR ALWAYS PROMPT RESPONSES. REGARDS, PB.

First type O is a subtype of HIV-1. We are just beginning to identify patients with this strain. Very few patients have been treated with subtype O, but they appear to respond to antiviral therapy like other HIV-1 strains. We don't know the natural history well to determine whether the strain is more virulent than other HIV-1 types. HIV-2 infection appears to cause less severe symptoms and slow if any progressive disease. We don't have much info on treatment with this strain. MH
