Can pus cells ( 30-40 hpf) mean hiv infection?

Not HIV. Other STD?: You mean in urine, right? HIV doesn't do this. White blood cells (WBC, "pus cells") in urine usually means bacterial infection. In males, this usually is an STD like gonorrhea or chlamydia, especially if discharge of mucus or pus from the penis, maybe with painful urination. You need medical attention ASAP. Since you're concerned about HIV, include HIV test. But it's not the cause of pus cells.
