    Figure 1. Early Symptoms of HIV. The stages of HIV infection are acute infection (also known as primary infection), latency, and AIDS. Acute infection lasts for several weeks and may include symptoms such as fever, swollen lymph nodes, inflammation of the throat, rash, muscle pain, malaise, and mouth and esophageal sores. The latency stage ...

    In the tonsils and adenoids of HIV-infected patients, macrophages fuse into multinucleated giant cells that produce huge amounts of virus. T-tropic strains of HIV-1, or syncytia-inducing strains (SI; now called X4 viruses [45]) replicate in primary CD4 + T cells as well as in macrophages and use the α-chemokine receptor, CXCR4, for entry. [46 ...

    HIV is a retrovirus that primarily infects components of the human immune system such as CD4 + T cells, macrophages and dendritic cells. It directly and indirectly destroys CD4 + T cells.

    This acute viremia is associated in virtually all people with the activation of CD8 + T cells, which kill HIV-infected cells, and subsequently with antibody production, or seroconversion. The CD8 + T cell response is thought to be important in controlling virus levels, which peak and then decline, as the CD4 + T cell counts rebound.

    After a spiked replication of HIV, the viral load and CD4 T cell count drops back down. Symptoms of acute HIV infection include fever, chills, rash, night sweats, muscle aches, and swollen lymph nodes. Acute symptoms occur usually 2–4 weeks after initial HIV infection and can last between a few days and several weeks [3]
