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.

HIV is a retrovirus that primarily infects components of the human immune system such as CD4 + T cells, macrophages and dendritic cells .
A good CD8 + T cell response has been linked to slower disease progression and a better prognosis, though it does not eliminate the virus. [3] During the acute phase, HIV-induced cell lysis and killing of infected cells by cytotoxic T cells accounts for CD4 + T cell depletion, although apoptosis may also be a factor.

Two types of HIV have been characterized: HIV-1 and HIV-2. HIV-1 is the virus that was initially discovered and termed both lymphadenopathy associated virus (LAV) and human T-lymphotropic virus 3 (HTLV-III). HIV-1 is more virulent and more infective than HIV-2, [20] and is the cause of the majority of HIV infections globally. The lower ...
SARS-CoV-2 and HIV-1 have similarities—notably both are RNA viruses—but there are important differences. As a retrovirus, HIV-1 can insert a copy of its RNA genome into the host's DNA, making total eradication more difficult. [156] The virus is also highly mutable making it a challenge for the adaptive immune system to develop a response.
The immune system does not have the ability to generate new T cells. Opportunistic infections, that a robust immune system could fight off, now are capable of causing severe symptoms and illnesses. Without a comprehensive anti-HIV drug therapy, an individual diagnosed with AIDS is expected to have less than three years to live.
