Which of the following is NOT a common viral disease?

• A. Adenovirus
• B. Mumps
• C. Cholera
• D. Herpes simplex

Answer: (C)

Cholera is a bacterial disease caused by the bacterium Vibrio cholerae, leading to severe diarrhea and dehydration. It is not viral in nature, which is why it is the correct choice for the question asking which is NOT a common viral disease. In contrast, adenovirus, mumps, and herpes simplex are all caused by viruses. Adenoviruses can cause a range of illnesses, including respiratory infections and conjunctivitis. Mumps is a viral infection characterized by swelling of the salivary glands, and herpes simplex refers to the viruses that cause oral and genital herpes. Understanding the difference between viral and bacterial infections is crucial for accurately identifying diseases and implementing effective treatment protocols.
