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 seeks out and destroys CCR5 expressing CD4 + cells during acute infection. A vigorous immune response eventually controls the infection and initiates the clinically latent phase. However, CD4 + T cells in mucosal tissues remain depleted throughout the infection, although enough remain to initially ward off life-threatening infections.
The CDC expanded the definition of HIV to include symptoms experienced by people of color and women in HIV trials and treatment recurrent pneumonia, pulmonary tuberculosis, stage III cervical cancer and recurrent vaginal candidiasis (yeast infections) [21] [34] The International Community of Women Living with HIV/AIDS (ICW) was founded. [11] 1993
HIV-1 infection causes chronic inflammation and production of reactive oxygen species. [86] Thus, the HIV genome may be vulnerable to oxidative damage, including breaks in the single-stranded RNA. For HIV, as well as for viruses in general, successful infection depends on overcoming host defense strategies that often include production of ...
Main symptoms of acute HIV infection. The initial period following infection with HIV is called acute HIV, primary HIV or acute retroviral syndrome. [29] [30] Many individuals develop an illness like influenza, mononucleosis or glandular fever 2–4 weeks after exposure while others have no significant symptoms.
HIV infections in adults typically follow a 3-stage course, as described below: Maculopapular Rash, note: this image shows a nonspecific rash that is not necessarily associated with an acute HIV infection Early Symptoms of HIV Diagram. Early, acute stage The early stage of an HIV infection involves rapid viral replication and infection. [9]
HIV encephalopathy; The presumptive criteria are designed for use where access to confirmatory diagnostic testing for HIV infection by means of virological testing (usually nucleic acid testing, NAT) or P24 antigen testing for infants and children aged under 18 months is not readily available.
WHO Disease Staging System for HIV Infection and Disease was first produced in 1990 by the World Health Organization [1] and updated in 2007. [2] It is an approach for use in resource limited settings and is widely used in Africa and Asia and has been a useful research tool in studies of progression to symptomatic HIV disease .
