Study Notes

HIV Stages

Acute HIV Infection: Occurs shortly after transmission, with flu-like symptoms, highly contagious.
Chronic HIV Infection: Virus remains active, gradually weakening the immune system, often without symptoms for years.
Symptomatic: Immune system weakens further, leading to frequent infections and illnesses.
AIDS: Final and most severe stage, resulting in life-threatening infections and cancers.

HIV Prevention

Rapid diagnostic tests and self-testing are available.
Prevention methods include condoms, regular testing, and antiretroviral drugs (PrEP, ART).

Rubella

Transmission: Spread through respiratory droplets when an infected person coughs or sneezes.
Symptoms: Fever, mild conjunctivitis, rash, swollen lymph glands, and occasionally joint pain in adults.
Risk: Congenital rubella syndrome (CRS) can lead to severe birth defects, including heart problems, deafness, and developmental delays.

Rubella Prevention

Immunization with the MMR (measles, mumps, and rubella) vaccine has significantly reduced rubella cases.

Herpes

Has three stages:
- Primary infection: HSV infects nearby nerve cells and replicates.
- Latency: Virus remains dormant in nerve cells.
- Reactivation: Infected cells wake up and trigger an immune response.

Herpes Prevention

Patients should refrain from oral contact or sexual activity with others to stop the spread.

Herpes Treatment

Medications for pain management include benzocaine, lidocaine, ibuprofen, naproxen, and paracetamol.
The frequency of breakouts can be decreased by taking medications at a lower daily dose.

Dengue

Caused by the Dengue virus (DENV).
Primarily transmitted by Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus.

Dengue Symptoms

High fever, nausea, body aches, joint pain.

Dengue Treatment

Hydration, rest, paracetamol (for fever and pain relief).

Dengue Prevention

Vector control: making the public aware, fogging, encouraging the use of mosquito repellents.
Vaccination: Dengvaxia is the first dengue vaccine developed, but only recommended for ages 9-24 with a prior dengue infection.

Meningitis

Inflammation of the leptomeninges (arachnoid and pia mater).

Meningitis Transmission

Viral meningitis: Spread through direct contact with respiratory secretions.

Hepatitis

Hepatitis A and E: Transmitted through the fecal-oral route (infected food or drink).
Hepatitis B, C, and D: Spread via blood transfusions, sex interactions, and perinatal transmission (mother to child).

Arthropod-Borne Viral Disease

Infections transmitted by ticks and mosquitoes.
Frequently encountered in Jamaica/Caribbean: dengue, chikungunya, and Zika virus.

Dengue (Arthropod-Borne Viral Disease)

Carried by Aedes Aegypti mosquitoes.
Symptoms: High temperature, excruciating headache, aches in the joints and muscles, and in extreme situations, shock or bleeding.

Chikungunya (Arthropod-Borne Viral Disease)

Spread by Aedes aegypti and Aedes albopictus mosquitoes.
Symptoms: Rash, fever, and discomfort in the muscles and joints.
Belongs to the family Togaviridae.

Zika (Arthropod-Borne Viral Disease)

Transmitted by Aedes mosquitoes.
Can cause fever, rash, joint discomfort, and conjunctivitis.
Belongs to the family Flaviviridae.

Zika Diagnosis and Treatment

Suspected based on symptoms, confirmation through blood or urine laboratory tests.
Currently, no targeted treatment for Zika virus infection. Individuals should seek medical attention.

Zika Prevention

Control mosquito populations by eliminating breeding sites, applying insect repellent, and wearing protective clothing (light colors).
No vaccine available for Zika virus infection.

Encephalitis

Inflammatory disorder of the brain, usually resulting from an infection or autoimmune reaction.

Encephalitis Transmission

Airborne viruses released by coughing or sneezing infected individuals.
Bites from infected insects (mosquitoes or ticks) and animals.
Contact with an infected individual.

Encephalitis Symptoms

Headache, fever, seizure, stiffness in the neck, loss of consciousness.

Encephalitis Treatment

Antiviral medications to address viral infections affecting the brain.
Breathing tube, urinary catheter, or feeding tube if the patient has lost consciousness due to encephalitis.

Encephalitis Diagnosis

Diagnosis established by exhibiting a combination of symptoms, including fever, seizures, or changes in behaviour and movement.
Confirmation through tests such as a brain MRI or CT scan, medical examination, and assessing the patient's medical history.
Blood, urine test, and stool test to detect antibodies associated with the infection.

Encephalitis Complications

Low blood pressure.
Decreased oxygen levels in the blood.
Bleeding within the brain.
Permanent brain damage.
Mortality.

Encephalitis Prevention

Maintain good hygiene and wash hands regularly.
Take precautions to avoid exposure to mosquitoes and ticks.
