Early symptoms of HIV infection in both men and women as fever, headache, tiredness and enlarged lymph nodes in the neck and groin, according to The National Institute of Allergy and Infectious Diseases (NIAID). Many patients mistake the symptoms as flu-like, which usually disappear in less than one month.
Not all men demonstrate symptoms during the early stages of HIV infection, according to the NIAID. Flu-like symptoms may occur within one to two months of infection, but do not appear in all men. During this period, men are very infectious, as there are large quantities of HIV in the semen and blood.
Symptoms of the later stages of infection, include rapid weight loss, recurring fever, severe fatigue, swollen lymph glands and diarrhea. Men suffering from late-stage HIV infection might also be prone to pneumonia, memory loss, sores in and around the mouth, anus and genitals and pink, red, brown or purple blotches that appear on the skin.
It is possible for some men with HIV to exhibit no symptoms for up to 12 years or more. Men engaging in sexual activity that places them at an increased risk for HIV are advised to be tested regularly, recommends the National Institute of Health.
