There are three periods after the infection, namely the acute phase, the asymptomatic phase and the AIDS phase. The acute phase occurs about 2-4 weeks after the initial infection. Some infected patients may experience fever, general malaise, headache, nausea, vomiting, diarrhea, joint pain, swollen lymph nodes, etc., but not frequent or urgent urination. In the asymptomatic phase often patients do not have obvious symptoms and can last about 6-8 years. Eventually the patient will enter the AIDS stage, in which the main manifestations are fever, night sweats, diarrhea lasting for more than one month, accompanied by weight loss of more than 10%, and can be followed by various infections, only when the inflammation of the urinary tract may appear the performance of frequent and urgent urination.
