The document discusses three conditions: HIV, polycythemia vera, and mononucleosis. HIV attacks T-cells, weakening the immune system and potentially leading to AIDS if untreated. While antiretroviral therapy can suppress HIV, there is no cure. Polycythemia vera causes overproduction of red blood cells, thickening blood and increasing clot risks, and is managed through aspirin, phlebotomy, and medications. Mononucleosis, commonly known as "the kissing disease," is caused by the Epstein-Barr virus and presents with lymphocyte abnormalities and potential liver/spleen issues, being treated through rest and relief of secondary infections.

2. HIV: Definition
 Human Immunodeficiency Virus
 Human can only infect humans
 Immunodeficiency weakens the immune system
 Virus reproduces itself, taking over the cells of the host
body
 Retrovirus
 Immune system can not get rid of this virus

3. HIV: What does it do?
 HIV attacks T-cells, the cells responsible for activating
an immune response for the body
 Without T-cells, the body can not fight infection and
disease
 When the body can no longer fight disease, the HIV
infection leads to its final stage; AIDS

4. HIV: Treatment
 Not all patients acquire AIDS
 Drugs can keep HIV at bay, and today, patients can live
a normal life
 Drug category: Antiretroviral therapy
 Abbreviation: ART
 May cause side effects
 No actual cure
 Alternative medicine is heavily turned to because of
side effects from ART

6. Polycythemia Vera: Broken
Down
 poly- = many
 cyt-/o = cell
 hem/o = blood
 -ia = condition
 Abbreviation: PV

7. Polycythemia Vera: Definition
 Rare blood disease where the bone marrow makes too
many red blood cells (RBCs)
 Blood becomes thicker and clots more than usual
 Easily made blood clots can cause heart attack or
stroke
 Slows the flow of oxygenated blood to the body

8. Polycythemia Vera: Treatment
 Can not be cured, however, treatments can still prevent
any complications from PV
 These options include
 Aspirin
 Drawing blood out of the veins (phlebotomy)
 Medications to suppress bone marrows ability to produce
RBCs

10. Mononucleosis: Broken Down
 mono- = one
 nucle/o = nucleus
 -osis = abnormal condition

11. Mononucleosis: Definition
 “The kissing disease”
 Acute infectious disease with large number of
mononuclear lymphocytes
 Caused by Epstein-Barr virus
 Accompanied by abnormal liver function or enlarged
spleen
 No medication to specifically treat this, only its
secondary infections

12. Mononucleosis: Treatment
 No medication to specifically treat this, only its
secondary infections
 Acetominophen or Ibuprofin help with pain and fever
 Getting plenty of rest and staying hydrated are the keys
to getting better
