Myositis is caused by infection/inflammation.

• A. True
• B. False
• C. Not stated
• D. It depends

Answer: (A)

Myositis means inflammation of muscle. That inflammation can be triggered by infections (infectious myositis) as well as by non-infectious inflammatory processes, such as autoimmune inflammatory myopathies. So the statement captures the essential idea that the disease is an inflammatory muscle condition and that infection can be one cause among others. While some cases are autoimmune without an infectious trigger, the inflammatory nature of myositis and the role of infection as a possible cause make the answer true.
