A detailed, exam-oriented medical study diagram for MBBS 3rd year students titled "TYPES OF EPIDEMIC & EPIDEMIC CURVE" from Park's Textbook of Preventive and Social Medicine, designed for KNRUHS university exam. Clean white background, professional medical textbook style with clear sections, bold headings, color-coded boxes, and labeled graphs. LAYOUT (top to bottom): --- TOP SECTION: CLASSIFICATION --- Large bold title at top: "TYPES OF EPIDEMIC (Park's Textbook - PSM)" A central classification tree branching into THREE main types: BOX A (blue, left): "A. COMMON-SOURCE EPIDEMICS" Two sub-boxes below it: - "(a) Single Exposure / POINT-SOURCE epidemic" - Example: Food poisoning, Bhopal gas tragedy - "(b) Continuous / Multiple Exposure epidemic" - Example: Legionnaire's disease 1976 Philadelphia, contaminated well water BOX B (green, center): "B. PROPAGATED EPIDEMICS" Three sub-boxes below it: - "(a) Person-to-person" - Example: Hepatitis A, Polio - "(b) Arthropod vector" - Example: Malaria, Dengue - "(c) Animal reservoir" - Example: Rabies, Plague BOX C (orange, right): "C. SLOW (MODERN) EPIDEMICS" One sub-box: - "Non-infectious chronic diseases" - Example: Obesity, Diabetes, Cancer, CVD --- MIDDLE SECTION: EPIDEMIC CURVES (3 side-by-side graphs) --- Section title: "EPIDEMIC CURVE = Graph of time distribution of cases (No. of Cases vs. Time)" Graph 1 (left, blue-bordered): Title: "Point-Source / Common-Source Epidemic" Draw a bell-shaped curve: starts at zero, rises sharply after a vertical arrow labeled "Exposure", reaches ONE single sharp peak, then falls rapidly back to zero. Label: "X-axis = Time, Y-axis = No. of Cases" Key features list below graph: - Single sharp peak - Explosive onset - All cases within ONE incubation period - Rapid rise AND fall - No secondary waves Graph 2 (center, green-bordered): Title: "Propagated / Person-to-Person Epidemic" Draw multiple peaks: starts low, then shows a small first hump, then larger second hump, then even larger third hump, gradually tailing off slowly to the right - like a series of successively taller waves (each separated by one incubation period interval). Key features list below graph: - Gradual rise - Multiple peaks (each = one incubation period apart) - Slow tail-off over LONG period - Ends when susceptibles depleted - e.g., Hepatitis A, Measles Graph 3 (right, orange-bordered): Title: "Continuous/Prolonged Common-Source Epidemic" Draw an irregular, jagged fluctuating line that starts, rises irregularly without a single sharp peak, persists over a wide time span, with no secondary waves but extended plateau-like appearance. Key features below: - No explosive onset - Irregular or extended pattern - Continues beyond one incubation period - No person-to-person spread - e.g., Contaminated water supply, Legionnaire's disease --- BOTTOM SECTION: KEY EXAM POINTS BOX --- A highlighted yellow box titled "HIGH-YIELD EXAM FACTS (Park's)" Bullet points: - Epidemic = occurrence of disease in excess of normal expectancy - Epidemic curve = graph of time distribution of cases - Median incubation period = time for 50% of cases to occur after exposure (used in point-source) - Point-source: cases all within ONE incubation period - Propagated: spread depends on herd immunity, contact opportunities, secondary attack rate - Mixed epidemic: starts as common-source, continues as propagated (e.g., water-borne cholera) - Slow epidemics: non-communicable diseases e.g. obesity, CVD, cancer Make text large enough to read clearly, use arrows and labels on graphs, color-code each type consistently throughout.

Below the ladder, a small info box: "Public Health Cut-offs (WHO): - Night blindness > 1% - Bitot's spots > 0.5% - Corneal xerosis/ulcer > 0.01% - Corneal scar > 0.05% - Serum retinol <10 mcg/dl in > 5%" Keep it simple with clear boxes, arrows showing progression, and bold labels. Suitable for hand-drawing in a university exam.
