Correct Option
The correct option is A-4, B-1, C-3, D-2
Explanation
Communicable diseases are caused by various pathogens, including bacteria, viruses, protozoa, and fungi. Understanding the nature of the causative agent is essential for diagnosis, treatment, and prevention strategies.
Detailed Analysis
- A. Tuberculosis (Bacteria): Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis, which is a bacterium. It primarily affects the lungs but can also affect other parts of the body. In the given list, this matches with Bacteria (Item 4).
- B. Measles (Virus): Measles is a highly contagious viral disease caused by the measles virus, a member of the paramyxovirus family. It is characterized by fever and a distinctive rash. This matches with Virus (Item 1).
- C. Malaria (Protozoa): Malaria is a life-threatening disease caused by parasites of the genus Plasmodium (e.g., P. falciparum, P. vivax). These parasites are protozoa and are transmitted to humans through the bites of infected female Anopheles mosquitoes. This matches with Protozoa (Item 3).
- D. Cholera (Bacteria): Cholera is an acute diarrheal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae. This matches with Bacteria (Item 2).
List II contains "Bacteria" at both index 2 and index 4. Since Tuberculosis and Cholera are both bacterial diseases, they correspond to these indices interchangeably based on the options provided. Option (a) correctly aligns Measles with Virus and Malaria with Protozoa, while assigning the two bacterial diseases to the available Bacteria slots.
Key Takeaway
Tuberculosis and Cholera are bacterial infections; Measles is a viral infection; and Malaria is a protozoan disease transmitted by vectors.
