DEFINITION
3
Acquired Immunodeficiency Syndrome (AIDS) is a
chronic, potentially life-threatening condition
caused by the Human Immunodeficiency Virus
(HIV). It weakens the immune system, making
individuals vulnerable to infections and other
illnesses.
HIV(HUMAN IMMUNODEFICIENCYVIRUS)
4
HIV targets the body’s white blood cells, weakening the
immune system. This makes it easier to get sick with diseases
like tuberculosis, infections and some cancers. HIV is spread
from the body fluids of an infected person, including blood,
breast milk, semen and vaginal fluids. It can also spread from a
mother to her baby.

SYMPTOMS
8
STAGES OF HIV
• Stage one: Acute HIV
• Stage two: Chronic HIV
• Stage three:AIDS
9
DIAGNOSIS
➢HIV Antibody Test
➢HIV Antigen Test
➢Nucleic acidTest
➢CD4 Cell Count
10
TREATMENT
• The treatment of AIDS primarily involves antiretroviral therapy
(ART), which aims to suppress the replication of the HIV virus,
improve immune function, and prevent the progression of HIV
infection to AIDS.This involves a combination of medications,
usually three or more drugs from different classes of antiretroviral
drugs.ART effectively controls HIV replication, reduces the viral
load in the body, and helps restore the immune system's function.
11
PREVENTION
12
➢ Get regular HIV testing
➢ Provide harm reduction services for injecting drug
users
➢ Ensure access to antiretroviral therapy
➢ Combat stigma and discrimination associated with
HIV/AIDS
➢ Promote comprehensive education and awareness
about HIV transmission and prevention
FUTURE DIRECTION
13
➢ Therapeutic HIVVaccines
➢ Broadly Neutralizing Antibodies
➢ Long-Acting Drugs
