Introduction
Retroviruses are a family of viruses characterized by their ability
to integrate their genetic material into the hostâ??s DNA. Among
them, the Human Immunodeficiency Virus (HIV) is the most wellknown
due to its association with Acquired Immunodeficiency
Syndrome (AIDS), a life-threatening condition that has affected
millions of people worldwide. This article provides an indepth
analysis of retroviruses, focusing on HIV, its structure,
mode of infection, treatment, and global impact. Retroviruses
belong to the Retroviridae family and are characterized by
their unique replication mechanism. Unlike most viruses that
use DNA as their genetic material, retroviruses contain RNA.
Upon infecting a host cell, these viruses use an enzyme called
reverse transcriptase to convert their RNA genome into DNA,
which then integrates into the hostâ??s genome. Retroviruses
typically have the following structural components. A lipid
bilayer derived from the host cell membrane, containing viral
glycoproteins essential for entry into target cells. A protein
shell that encases the viral RNA and essential enzymes. Two
identical single-stranded RNA molecules. Reverse transcriptase,
integrase, and protease, which play crucial roles in viral
replication and integration. HIV is a member of the Lentivirus
genus within the Retroviridae family. It primarily targets the
human immune system, weakening its ability to fight infections
and diseases [1,2].
Description
Without treatment, HIV can lead to AIDS, a condition in which
the immune system becomes severely compromised. HIV shares
the general structural features of retroviruses but has unique
adaptations that enable it to infect immune cells effectively,
facilitate attachment and entry into host cells. Capsid Protein
Protects the viral genome and aids in infection. RNA Genome
and Essential Enzymes allow the virus to replicate and integrate
into the host DNA. The life cycle of HIV follows a series of
well-defined steps are HIV binds to the CD4 receptors and coreceptors
(CCR5 or CXCR4) on host immune cells, primarily
T-helper cells. The viral RNA is converted into DNA by reverse
transcriptase. The viral DNA integrates into the host genome via
the enzyme integrase [3,4]. The host cell machinery produces
viral RNA and proteins. New viral particles are assembled and
released, maturing into infectious virions through the action
of protease. HIV is transmitted through contact with infected
bodily fluids, such as Blood (e.g., through needle sharing or
transfusions with contaminated blood). Semen and vaginal
fluids (e.g., through unprotected sexual intercourse). Breast
milk (e.g., from mother to child during breastfeeding). Vertical
transmission from mother to child during childbirth. HIV is not
transmitted through casual contact, hugging, sharing utensils,
or mosquito bites.
Conclusion
HIV infection progresses through several stages acute HIV
Infection (2-4 weeks post-infection) symptoms resemble flu,
including fever, swollen lymph nodes, and rash. Chronic HIV
Infection (Clinical Latency Stage) the virus remains in the body,
replicating at low levels. The person may be asymptomatic for
years. The final stage, where the immune system is severely
weakened, leading to opportunistic infections and cancers.
Without treatment, AIDS is fatal. HIV is diagnosed through
various tests, including Detect HIV antibodies in blood or
saliva. Antigen/Antibody Tests Detect both HIV antigens and
antibodies. Nucleic Acid Tests (NATs) Detect viral RNA directly
and are used for early diagnosis. Early diagnosis is crucial for
effective management and prevention of HIV transmission.
