Stages of HIV infection
There are four stages of HIV infection: 1) Primary infection lasts a few weeks and causes flu-like symptoms; 2) Asymptomatic stage lasts around 10 years without symptoms but HIV is still active; 3) Symptomatic infection where the immune system is damaged over time causing worsening symptoms and opportunistic infections; 4) Progression to AIDS where the T cell count drops below 200 and opportunistic infections worsen.

Introduction to HIV infection stages, highlighting effects on lymphatic and CNS.
Details on Stage One: symptoms include flu-like illness, often missed diagnosis, lasts weeks.
In Stage Two, lasts about ten years; individuals remain asymptomatic but still infectious.
Stage Three shows immune system damage, increased mutations of HIV, and opportunistic infections.
Stage Four defined by severe drop in T cell count, leading to worsening opportunistic infections.
Impact on various body systems: respiratory, gastrointestinal, CNS, and integumentary with specific diseases.
Stages of HIV infection
- 1. Stages of HIVInfection HIV infect cells in the Lymphatic and Central Nervous System
- 2. STAGES OF HIVINFECTION
- 3. Stages of Infection Stage One: Primary HIV Infection Lasts for a few weeks Infectious Flu like illness (fever, diarrhea, wt loss, swollen glands) 20% of people with symptoms are serious enough to go to a physician (diagnosis is often missed)
- 4. Stage Two: ClinicallyAsymptomatic Stage Lasts for an average of ten years Free from major symptoms (swollen glands) Infectious Very active in Lymph nodes Viral lode test
- 5. Stage Three: SymptomaticHIV Infection Over time immune system (lymphatic) becomes severely damaged HIV mutates and becomes stronger and destroys more T cells Lymphatic system deteriorated and symptoms worsen Opportunistic Infections
- 6. Stage Four: Progressionfrom HIV to AIDS T cell count drops to 200 Opportunistic Infections worsen
- 7. Effects on BodySystems Respiratory System: Tuberculosis Pneumonia Kaposi Sarcoma
- 8. Gastrointestinal System (Digestive) Candida (fungus) Isosporiasis Cryptomegolavirus Kaposi Sarcoma
- 9. CNS (Central NervousSystem) HIV Toxoplasmosis Non Hodgkin Lymphoma Zoster Herpes Simplex AIDS Dementia Complex
- 10. Integumentary System Fungalnail infections Herpes Simplex Zoster Kaposi Sarcoma
