positive enzyme-linked immunosorbent assay (ELISA) does not indicate true HIV infection.
The detection of HIV in infants is confirmed by a p24 antigen assay, virus culture of HIV, or polymerase chain
reaction. A Western blot test confirms the presence of HIV antibodies. The CD4+ cell count indicates how well the immune
system is working. A chest x-ray evaluates the presence of other manifestations of HIV infection, such as pneumonia.
AIDS is a disorder caused by the human immunodeficiency virus (HIV) and is characterized by a generalized
dysfunction of the immune system. Home care instructions include the following: frequent hand washing; monitoring for fever,
