Answer
Measles, hepatitis B and norovirus
Explanation
This question is testing your knowledge on different types of infectious agents. Viruses are microscopic parasites, generally much smaller than bacteria and contagious in nature. The measles, hepatitis B, and norovirus stand as correct examples of viruses, since they all have viral etiology. Thrush (caused by Candida fungus), ringworm (caused by fungi), and athlete’s foot (also caused by fungi), are all fungal diseases. MRSA (Methicillin-resistant Staphylococcus aureus), Legionella, and Clostridium difficile are bacterial diseases. Finally, lice, scabies and bed bugs are ectoparasites, thus are excluded from the category of viruses.
