This article presents basic information on the clinical features of HIV infection, most of which are related to the profound immune deficiency associated with HIV/AIDS. Primary HIV infection is associated with clinical symptoms, primarily a mononucleosis syndrome, in about 50% of cases. In the ensuing 10 years, more than 50% of HIV-infected individuals develop the opportunistic infections (OIs) indicative of the onset of AIDS. Common presentations of AIDS include pneumonia, dysphagia, diarrhea, neurologic symptoms, fever, wasting, anemia, and vision loss. Monitoring of peripheral blood CD4 T-lymphocytes provides a measure of the current risk of OIs and a guide for antiretroviral therapy. Protease inhibitors, used in combination with other antiretrovirals, allow long-term control of HIV disease, but the substantial cost of these drugs has prohibited their widespread use in developing countries. Treatment of HIV-related infections must be followed by a maintenance regimen intended to prevent relapse.

Primary HIV infection can occur in 40-90% of individuals recently infected with HIV. Variable symptoms usually suggestive of a flu-like illness as well as high-level HIV viraemia and steep decline in CD4 cell count are often noted. We report a case of a previously healthy homosexual man who presented with symptoms suspicious of primary HIV infection as well as non-productive cough associated with chest CT finding of diffuse ground glass appearance in lungs. Recent HIV seroconversion was confirmed. Diagnosis of Pneumocystis jirovecii pneumonia was made on transbronchial lung biopsy. The symptoms improved rapidly after initiation of treatment with trimethoprim-sulfamethoxazole. It is important to recognise that although Pneumocystis pneumonia is generally seen in the setting of AIDS, it can occasionally also occur during primary HIV infection.
