When someone is infected with HIV, they do not have to progress to AIDS to develop symptoms. There is a known Acute Retroviral Syndrome that presents with many of the symptoms you are describing (fever, malaise, sore throat, nausea/vomiting). This is found in 50-70% of HIV infected individuals, and generally occurs 3-6 weeks after infection. The symptoms generally last anywhere from 1 week - 3 months. If you are a known to have been exposed to Hepatitis B, many of the same symptoms can be associated with an acute flare of the disease. In any event, seeing a doctor is critical, as early intervention with medication can prevent or delay many of the long-term effects of these diseases. Seriously I would suggest everyone(married & unmarried) should get tested on HIV/STDS every other year....but too bad that people think they dont need it...
