Which of the following diseases is NOT associated with bacilli?

Measles is not associated with bacilli because it is caused by a virus, specifically the measles virus (Morbillivirus). Bacilli are rod-shaped bacteria, and the diseases associated with bacilli are typically bacterial infections, such as tuberculosis caused by Mycobacterium tuberculosis, lockjaw (tetanus) caused by Clostridium tetani, and diphtheria caused by Corynebacterium diphtheriae. In contrast, measles is a viral infection characterized by a distinct rash and respiratory symptoms, making it fundamentally different from diseases caused by bacilli. Understanding the distinction between viral and bacterial infections is crucial in sanitation, disinfection, and safety practices, as each category requires different approaches for prevention and control.
