Disease-Cause (Medium)

Disease-Cause problems require matching diseases with their causative agents (bacteria, viruses, protozoa, fungi, or nutritional deficiencies). These problems test knowledge of medical science and disease pathology. Common pairs include Malaria-Protozoa, Tuberculosis-Bacteria, Common Cold-Virus, and Rickets-Vitamin D Deficiency.

Introduction to Disease-Cause (Medium)

Disease-Cause problems require matching diseases with their causative agents (bacteria, viruses, protozoa, fungi, or nutritional deficiencies). These problems test knowledge of medical science and disease pathology. Common pairs include Malaria-Protozoa, Tuberculosis-Bacteria, Common Cold-Virus, and Rickets-Vitamin D Deficiency.

Prerequisites

Knowledge of common diseases Familiarity with pathogens (bacteria, virus, protozoa, fungus) Understanding of deficiency diseases Awareness of disease transmission
Why This Matters: Disease-Cause problems appear in 1-2 questions in SSC CGL and Banking PO exams. They test basic medical knowledge.

How to Solve Disease-Cause (Medium) Problems

1

Step 1: Identify the disease in the first part of the analogy

2

Step 2: Recall the causative agent or cause of that disease

3

Step 3: Identify the second disease in the analogy

4

Step 4: Recall the cause of the second disease

5

Step 5: Verify that both pairs follow disease → cause relationship

6

Step 6: Answer with the correct causative agent

Pro Strategy: Group diseases by causative agent type: Bacterial (TB, Typhoid, Cholera, Pneumonia, Tetanus), Viral (Common Cold, COVID-19, Dengue, Polio, Measles, Rabies), Protozoan (Malaria, Amoebiasis, Sleeping sickness), Fungal (Ringworm, Candidiasis), Nutritional deficiency (Rickets, Scurvy, Beriberi, Anemia).

Example Problem

Example: Malaria : Protozoa :: Tuberculosis : ? Solution: Step 1: First disease = Malaria Step 2: Malaria is caused by Plasmodium (Protozoa) Step 3: Second disease = Tuberculosis Step 4: Tuberculosis is caused by Mycobacterium tuberculosis (Bacteria) Answer: Bacteria

Pro Tips & Tricks

  • Malaria → Protozoa (Plasmodium)
  • Tuberculosis → Bacteria (Mycobacterium tuberculosis)
  • Common Cold → Virus (Rhinovirus, Coronavirus)
  • COVID-19 → Virus (SARS-CoV-2)
  • Dengue → Virus (Dengue virus)
  • Cholera → Bacteria (Vibrio cholerae)

Shortcut Methods to Solve Faster

Malaria → Protozoa
TB → Bacteria
Common Cold → Virus
COVID-19 → Virus
Dengue → Virus
Cholera → Bacteria
Typhoid → Bacteria
Rickets → Vitamin D Deficiency
Scurvy → Vitamin C Deficiency

Common Mistakes to Avoid

Confusing viral diseases with bacterial ones
Thinking all respiratory infections are viral (some are bacterial)
Forgetting that rickets is caused by Vitamin D deficiency (not calcium deficiency directly)
Assuming all diseases have a single causative agent (some have multiple)
