Blood in the stool has nothing to do with the acute phase of hiv, HIV infection can lead to AIDS, in the acute phase of AIDS, patients often show fever, sore throat, nausea, vomiting and other symptoms, not blood in the stool, and then enter the asymptomatic period of up to 8~9 years, and ultimately enter the AIDS stage. HIV, also known as human immunodeficiency virus, is a virus that can lead to AIDS. During the initial 2-4 weeks of HIV infection, which is also known as the acute phase of AIDS, patients may experience fever, sore throat, nausea, vomiting, muscle aches and pains, skin rashes, arthralgia, and enlarged lymph nodes, but will not experience blood in their stools. After the acute phase of AIDS, patients can enter an asymptomatic phase of up to 8 to 9 years, during which patients have no symptoms and do not have blood in the stool. Eventually the patient will enter the AIDS stage, where the patient can experience a range of symptoms of reduced immune function, such as thrush, Pneumocystis pneumonia, Kaposi’s sarcoma, and lymphoma. If you have had high-risk sex and may be infected with HIV, go to your local regular hospital or CDC as soon as possible.
