Which disease is commonly caused by bacteria?

• A. Strep throat
• B. Chicken pox
• C. Measles
• D. Mumps

Answer: (A)

Understanding what causes a disease is key. Strep throat is caused by a type of bacteria called Streptococcus, so this condition is a bacterial infection. That stands in contrast to the other options, which are caused by viruses—the chickenpox virus, the measles virus, and the mumps virus. Because bacteria are the culprit here, antibiotics can be effective, whereas for these viral illnesses antibiotics typically don’t help. So among these, the disease most commonly caused by bacteria is the one linked to a bacterial pathogen.
