Verified step by step guidance1
Step 1: Understand the nature of each disease listed. Influenza is caused by viruses, Malaria is caused by protozoan parasites, and Tuberculosis is caused by bacteria.
Step 2: Recognize that Pneumonia is a condition characterized by inflammation of the lungs and can be caused by multiple types of pathogens, including bacteria, viruses, and sometimes fungi.
Step 3: Identify that the question asks which disease can be caused by either bacterial or viral infections, so focus on diseases with multiple possible infectious agents.
Step 4: Compare the causative agents of each disease: Influenza (viral only), Malaria (protozoan only), Tuberculosis (bacterial only), and Pneumonia (both bacterial and viral).
Step 5: Conclude that Pneumonia fits the criteria because it can be caused by both bacterial and viral pathogens, unlike the other diseases listed.
