Causes
HIV, or Human Immunodeficiency Virus, remains a persistent global health challenge, affecting millions of individuals worldwide. The transmission of HIV primarily occurs through certain bodily fluids, including blood, semen, vaginal fluids, and breast milk. Unprotected sexual intercourse with an infected individual constitutes the most common mode of transmission, accounting for a significant proportion of new HIV infections globally. Additionally, sharing needles contaminated with HIV-infected blood, often associated with intravenous drug use, poses a significant risk of HIV transmission. Furthermore, perinatal transmission from an HIV-positive mother to her child during pregnancy, childbirth, or breastfeeding can occur if appropriate preventive measures are not implemented.
Understanding the diverse ways in which HIV can be transmitted is essential for effective prevention strategies. Health education initiatives play a crucial role in raising awareness about HIV transmission routes, encouraging safer sexual practices, promoting the use of sterile injection equipment, and advocating for prenatal HIV testing and interventions to prevent mother-to-child transmission. Efforts to combat HIV transmission also encompass initiatives aimed at reducing stigma and discrimination, addressing socio-economic factors contributing to vulnerability, and promoting access to comprehensive healthcare services, including HIV testing, counseling, and treatment.
Despite significant progress in HIV prevention and control efforts, challenges persist in achieving universal access to prevention measures and treatment services, particularly in resource-limited settings. Continued investment in research, healthcare infrastructure, and community-based interventions is essential to accelerate progress towards the global goal of ending the HIV/AIDS epidemic. By addressing the underlying determinants of HIV transmission and implementing evidence-based interventions, we can work towards a future where HIV/AIDS no longer poses a significant public health threat.

Signs and Symptoms
Early HIV infection often presents with nonspecific symptoms that can be mistaken for other common illnesses. These symptoms typically manifest within a few weeks to months after initial infection and may include fever, fatigue, sore throat, swollen lymph nodes, and rash. However, it’s important to note that not everyone with HIV will experience these early symptoms, and some individuals may remain asymptomatic for years.
As the virus progresses, it targets and destroys CD4 cells, weakening the immune system and making the body more susceptible to opportunistic infections and other complications. Consequently, the signs and symptoms of HIV can vary widely depending on the stage of the infection and the presence of associated conditions.
Common complications of advanced HIV infection include recurrent respiratory infections, chronic diarrhea, weight loss, oral thrush, and skin lesions. Additionally, HIV-related neurocognitive disorders, such as HIV-associated neurocognitive impairment and HIV-associated dementia, can manifest with cognitive deficits, motor dysfunction, and behavioral changes.
Furthermore, HIV increases the risk of developing certain cancers, particularly those associated with viral infections such as Kaposi’s sarcoma, non-Hodgkin lymphoma, and cervical cancer. These malignancies may present with specific signs and symptoms depending on their location and extent of spread.
It’s essential for individuals at risk of HIV infection to undergo regular HIV testing, even in the absence of symptoms, as early detection and intervention can significantly improve treatment outcomes. Additionally, healthcare providers should maintain a high index of suspicion for HIV in patients presenting with symptoms suggestive of acute retroviral syndrome or opportunistic infections, particularly in populations with known risk factors for HIV transmission. By recognizing and promptly addressing the signs and symptoms of HIV, healthcare professionals can facilitate timely diagnosis, treatment initiation, and supportive care for individuals living with HIV/AIDS.

Etiology
HIV is a retrovirus belonging to the family of Lentiviridae, known for their ability to cause chronic and progressive diseases in their hosts. The virus primarily targets CD4-positive T cells, a type of white blood cell crucial for orchestrating the immune response against pathogens. Upon entry into the bloodstream, HIV binds to CD4 receptors on the surface of T cells, facilitating viral entry and subsequent infection.
The entry of HIV into target cells is mediated by viral envelope glycoproteins, particularly the gp120 protein, which interacts with CD4 receptors and co-receptors such as CCR5 and CXCR4. This interaction triggers a cascade of events leading to viral fusion with the host cell membrane and the release of viral genetic material into the cell.
Once inside the host cell, HIV undergoes reverse transcription, a process where viral RNA is converted into DNA by the enzyme reverse transcriptase. The viral DNA is then integrated into the host cell genome by the viral integrase enzyme, allowing the virus to hijack the host cell’s machinery for its replication.
The integrated viral DNA, known as provirus, can remain latent within the host cell, escaping immune detection and antiretroviral therapy. Periodically, the provirus can become activated, leading to the production of new viral particles and the spread of infection to other cells.
The progressive depletion of CD4 T cells by HIV ultimately results in immune system dysfunction, rendering the host susceptible to opportunistic infections and malignancies characteristic of AIDS. The pathogenesis of HIV/AIDS is complex and multifactorial, involving interactions between viral and host factors, immune responses, and environmental influences.
Understanding the etiology of HIV/AIDS is essential for developing targeted interventions aimed at preventing viral transmission, preserving immune function, and improving clinical outcomes for individuals living with HIV/AIDS. By elucidating the molecular mechanisms underlying HIV infection and pathogenesis, researchers can identify new therapeutic targets and strategies for controlling the spread of the virus.

Pathophysiology
The pathophysiology of HIV infection involves a complex interplay between the virus and the host immune system, leading to progressive immune dysfunction and the development of AIDS. Upon entry into the bloodstream, HIV targets CD4-positive T cells, which play a central role in coordinating the immune response against pathogens.
The initial interaction between HIV and CD4 receptors on T cells triggers viral entry and subsequent infection. The virus utilizes co-receptors such as CCR5 and CXCR4 to facilitate fusion with the host cell membrane, allowing the release of viral genetic material into the cell.
Once inside the host cell, HIV undergoes reverse transcription, where viral RNA is converted into DNA by the enzyme reverse transcriptase. The viral DNA is then integrated into the host cell genome by the viral integrase enzyme, establishing a reservoir of latent viral DNA within infected cells.
The integrated viral DNA can remain dormant or latent within the host cell, evading immune detection and antiretroviral therapy. Periodically, factors such as immune activation or cytokine signaling can trigger the activation of latent provirus, leading to viral replication and the production of new viral particles.
The progressive depletion of CD4 T cells by HIV undermines the host immune response, impairing the body’s ability to mount an effective defense against opportunistic infections and malignancies. Additionally, chronic immune activation and inflammation contribute to tissue damage and systemic complications associated with HIV/AIDS.
The pathophysiology of HIV/AIDS is characterized by dynamic interactions between viral and host factors, immune responses, and environmental influences. Understanding these complex mechanisms is essential for developing targeted therapeutic interventions aimed at suppressing viral replication, preserving immune function, and improving clinical outcomes for individuals living with HIV/AIDS. By elucidating the underlying pathophysiological processes, researchers can identify new strategies for controlling HIV infection and preventing the progression to AIDS.

DSM-5 Diagnosis
While HIV infection itself is not classified as a mental disorder, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), includes criteria for diagnosing neurocognitive disorders associated with HIV. These disorders, previously known as HIV-associated neurocognitive disorders (HAND), encompass a spectrum of cognitive impairments resulting from HIV-induced central nervous system damage.
The DSM-5 outlines criteria for two main categories of neurocognitive disorders: major neurocognitive disorder and mild neurocognitive disorder. Major neurocognitive disorder is characterized by significant cognitive decline from a previous level of performance in one or more cognitive domains, such as memory, attention, executive function, language, or visuospatial ability. In contrast, mild neurocognitive disorder involves modest cognitive decline that does not interfere significantly with daily functioning.
To meet the criteria for a diagnosis of HIV-associated neurocognitive disorder, the individual must demonstrate evidence of cognitive impairment that is attributable to HIV infection, as evidenced by neuroimaging studies, cerebrospinal fluid analysis, or neuropsychological testing. The cognitive deficits must significantly impair the individual’s ability to perform everyday activities and represent a decline from a previous level of functioning.
Common cognitive impairments associated with HIV include deficits in attention, concentration, memory, executive function, processing speed, and motor skills. These cognitive deficits can manifest with difficulties in maintaining attention, organizing tasks, problem-solving, remembering information, and executing complex motor tasks.
Diagnosing HIV-associated neurocognitive disorders requires a comprehensive assessment that includes a thorough medical history, physical examination, neuropsychological testing, and ancillary investigations to rule out other potential causes of cognitive impairment. Early detection and intervention are crucial for optimizing treatment outcomes and improving the quality of life for individuals living with HIV-associated neurocognitive disorders.

Treatment Regimens and Patient Education
Antiretroviral therapy (ART) forms the cornerstone of HIV treatment, aiming to suppress viral replication, preserve immune function, and improve quality of life for individuals living with HIV/AIDS. Modern ART regimens typically consist of a combination of antiretroviral drugs from different classes, targeting various stages of the HIV life cycle.
The goal of ART is to achieve and maintain viral suppression, defined as reducing the viral load to undetectable levels, usually below 50 copies of HIV RNA per milliliter of blood. Viral suppression not only benefits the individual’s health but also reduces the risk of transmitting HIV to others through sexual contact or needle sharing.
ART regimens may include nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), integrase strand transfer inhibitors (INSTIs), and entry inhibitors. These drugs work by inhibiting viral replication at different stages of the HIV life cycle, thereby slowing disease progression and reducing the risk of developing opportunistic infections and AIDS-related complications.
Adherence to ART is crucial for treatment success and long-term viral suppression. Patients must take their medications as prescribed, following the recommended dosing schedule and avoiding interruptions in treatment. Poor adherence can lead to virologic failure, drug resistance, and disease progression.
Patient education plays a vital role in promoting adherence to ART and optimizing treatment outcomes. Healthcare providers should educate patients about the importance of medication adherence, potential side effects of antiretroviral drugs, and strategies for managing adverse reactions. Patients should also be informed about the significance of regular follow-up appointments and monitoring tests to assess treatment efficacy and detect any complications early.
Additionally, patient education should address preventive measures to reduce the risk of HIV transmission to others. This includes practicing safer sex by using condoms consistently and correctly, avoiding sharing needles or other injection equipment, and discussing HIV status openly with sexual partners.
Furthermore, patients living with HIV/AIDS may benefit from comprehensive support services, including mental health counseling, peer support groups, and assistance with accessing social services and community resources. By empowering patients with knowledge, skills, and support, healthcare providers can enhance treatment adherence, improve health outcomes, and promote overall well-being for individuals living with HIV/AIDS.
