Trichomoniasis is caused by the vaginal parasite Trichomonas vaginalis and is primarily transmitted through sexual contact, though it can also spread indirectly. The main symptoms include abnormal vaginal discharge and itching of the vulva. The discharge may be thin and purulent or frothy and malodorous. On the other hand, HIV requires blood tests to detect HIV antibodies to determine if one has the disease. The examination processes for these two are distinct. Therefore, it is not possible to determine HIV status from a trichomoniasis test; trichomoniasis is diagnosed through vaginal discharge, whereas HIV is diagnosed through blood tests.
