Here's what's covered in the notes (with full explanations):
MALARIA — Complete Notes Summary
1. Introduction
- Protozoal infection caused by Plasmodium spp., transmitted by female Anopheles mosquito
- Destroys hepatocytes + RBCs → fever, anemia, jaundice
5 Plasmodium species table with RBC preference for each
2. Life Cycle (5 Stages)
| Stage | What Happens |
|---|---|
| Stage 1 | Mosquito injects sporozoites → liver within 30 min |
| Stage 2 | Liver stage — hepatic schizogony → thousands of merozoites released (1–2 weeks) |
| Stage 3 | Blood stage — merozoites enter RBCs → Ring → Trophozoite → Schizont |
| Stage 4 | RBC rupture → hemozoin + toxins → fever (48h vivax, 72h malariae, continuous falciparum) |
| Stage 5 | Gametocyte formation → mosquito picks them up → sexual cycle |
Hypnozoites (P. vivax + P. ovale only) — dormant liver forms causing relapses
3. Signs & Symptoms
- Classic Paroxysm: Chills → High Fever → Sweating (matches RBC rupture)
- Other: headache, body pain, fatigue, splenomegaly, jaundice
Severe malaria (P. falciparum) — 7 complications explained (cerebral malaria via PfEMP-1, blackwater fever, hypoglycemia, shock, multi-organ failure)
4. Diagnosis
| Test | Purpose |
|---|---|
| Thick smear | Detects parasite |
| Thin smear | Identifies species |
| RDT (HRP2) | Quick falciparum detection |
| RDT (pLDH) | Other species |
| CBC / LFT / RFT | Anemia, complications |
5. Treatment (Fully Explained)
- P. falciparum → ACT (Artemether-Lumefantrine, Artesunate+SP, DHP) x 3 days — why ACT explained
- P. vivax / ovale → Chloroquine + Primaquine 14 days (kills hypnozoites) — G6PD warning explained
- P. malariae / knowlesi → Chloroquine first-line
- Severe malaria → IV Artesunate → oral ACT once stable
6. Prevention
- Personal: mosquito nets, repellents, long sleeves, no stagnant water
- Community: fogging, larvicidal sprays, IRS
- Chemoprophylaxis: Chloroquine / Mefloquine / Malarone depending on region

Typhoid Fever Notes
PDF Document · PDF
Here's what the PDF contains across 8 sections:
1. Introduction
- S. Typhi vs Salmonellosis — key difference explained
- Endemic regions, paratyphoid comparison
2. Cause & Transmission
- Fecal-oral/urine-oral routes in a color table
- Chronic Carrier concept explained (Typhoid Mary, gallbladder reservoir)
3. Pathology — 8-Step Flowchart (box → arrow → box)
| Step | What Happens |
|---|---|
| 1 | Ingestion of S. Typhi (survives stomach acid) |
| 2 | Invades ileum via M cells over Peyer's patches |
| 3 | Replicates in lymphoid tissue → mesenteric lymphadenopathy |
| 4 | Primary bacteremia (Week 1) → liver, spleen, bone marrow |
| 5 | Intracellular multiplication in Kupffer cells → secondary bacteremia |
| 6 | Bacteria re-enter gut via bile → re-infect Peyer's patches → necrosis |
| 7 | Ulcers form → hemorrhage or perforation → rose spots |
| 8 | Resolution (with Rx) OR sepsis/carrier state (without Rx) |
4. Signs & Symptoms
- Stepladder fever pattern explained
- Rose spots explained
- Complications side-by-side table
5. Diagnostic Tests
- Blood culture (gold standard, Week 1)
- Widal test limitations fully explained
- IgM Typhidot, PCR, Stool culture
6. Treatment — Antibiotics Explained
| Drug | Mechanism | Use |
|---|---|---|
| Fluoroquinolones (Cipro) | Inhibit DNA gyrase | 1st choice |
| Ceftriaxone | Block cell wall synthesis | MDR typhoid |
| Azithromycin | Inhibit protein synthesis | Resistant cases |
| Carbapenems | Cell wall (beta-lactamase resistant) | XDR typhoid |
7. Prevention — Vaccines Table
- Inactivated (Vi-PS), Live oral (Ty21a), Tybar-TCV (from 6 months) fully explained

Here's what's inside across 9 sections:
1. Introduction
- ssRNA virus, family Orthomyxoviridae
- Types A/B/C/D with key differences in a color table
- H (Hemagglutinin) and N (Neuraminidase) proteins explained
- Antigenic Drift vs Antigenic Shift — why annual vaccine is needed
2. Mode of Transmission
- Droplets, direct contact, fomites, airborne — full table with range/details
- Infectious 1 day BEFORE symptoms (explains rapid spread)
3. Pathophysiology — 7-Step Flowchart
| Step | What Happens |
|---|---|
| 1 | Virus enters via respiratory tract |
| 2 | Hemagglutinin (H) attaches to sialic acid receptors |
| 3 | Viral replication inside epithelial cells |
| 4 | Neuraminidase (N) releases new virions — drug target |
| 5 | Cytokine storm → sudden fever, myalgia, fatigue |
| 6 | Epithelial death + cilia destroyed → mucociliary clearance lost |
| 7 | Secondary bacterial infection (Staph/Strep) → pneumonia |
4. High Risk Groups
- Elderly, children <5, pregnant, COPD/asthma/diabetes, immunocompromised, HCWs — all explained with reasoning
5. Signs & Symptoms
- Adult vs children symptoms side-by-side
6. Complications
- Viral/bacterial pneumonia, otitis media, COPD exacerbation, myocarditis, encephalitis — all explained
7. Diagnosis
- RIDT (rapid, low sensitivity), RT-PCR (gold standard), clinical diagnosis
8. Treatment & Prevention
- Oseltamivir (mechanism explained), Zanamivir, Baloxavir (different mechanism - RNA polymerase)
- Aspirin avoided in children — Reye's syndrome explained
- Supportive care + full prevention table including annual vaccine
9. Quick Revision — 15 Key Facts Table
