My brother has a low platelet count and he often gets sick, bronchitis, pneumonia, chicken pox (x2), shingles. She seems in pretty good health except for her yearly pneumonia or bronchitis. She was adopted as a child and is now 22 years old and not sexually active. Recently a blood test came back saying she was hiv+. Is it possible that hiv can appear after 22 years? could this be cvid?
