AIDS (Acquired Immuno Deficiency Syndrome)
Comprehensive understanding of AIDS, its causative agent (HIV), mode of transmission, replication cycle, diagnosis, and prevention.
What is AIDS (Acquired Immuno Deficiency Syndrome)?
Acquired Immuno Deficiency Syndrome: The late stage of HIV infection where the immune system is severely damaged.
Key points
- Identify HIV as the causative agent of AIDS.
- Describe the mechanism of immune system damage by HIV.
- List the modes of HIV transmission.
- Explain the diagnostic methods for HIV/AIDS.
Common exam trap
Confusing HIV with AIDS (AIDS is the condition, HIV is the virus).
Definitions
- Term
AIDS
- Meaning
Acquired Immuno Deficiency Syndrome: The late stage of HIV infection where the immune system is severely damaged.
- Term
HIV
- Meaning
Human Immunodeficiency Virus: A retrovirus that attacks the immune system, primarily CD4 T-cells.
- Term
CD4 T-lymphocytes
- Meaning
A type of white blood cell that plays a central role in the immune system; targeted and destroyed by HIV.
- Term
Opportunistic Infection
- Meaning
An infection caused by pathogens that do not usually cause disease in a healthy person with a normal immune system.
- Term
Antiretroviral Therapy (ART)
- Meaning
A combination of drugs used to treat HIV infection, which suppresses the virus and allows the immune system to recover.
Learning objectives
Identify HIV as the causative agent of AIDS.
Describe the mechanism of immune system damage by HIV.
List the modes of HIV transmission.
Explain the diagnostic methods for HIV/AIDS.
Outline the principles of ART and its role in managing HIV/AIDS.
Discuss preventive measures against HIV infection.
Prerequisites
Basic understanding of the human immune system.
Knowledge of viruses and their replication.
Concepts of infectious diseases and transmission.
Common mistakes
Confusing HIV with AIDS (AIDS is the condition, HIV is the virus).
Believing HIV can be transmitted through casual contact (hugging, kissing, sharing utensils).
Underestimating the importance of early diagnosis and treatment.
Not understanding the different modes of transmission.
Assuming ART is a cure rather than a management strategy.
