Typhoid fever is correctly identified as a disease commonly caused by bacilli. Bacilli are rod-shaped bacteria, and the causative agent of typhoid fever is Salmonella enterica serotype Typhi, which belongs to this group. This bacterial infection is primarily transmitted through contaminated food and water, leading to a systemic illness characterized by prolonged fever, abdominal pain, and gastrointestinal symptoms.

In contrast, malaria is caused by protozoan parasites of the genus Plasmodium, not by bacilli. Herpes is caused by viruses, specifically the herpes simplex virus. Chickenpox is also a viral infection caused by the varicella-zoster virus. These distinctions help clarify why typhoid fever is appropriately associated with bacilli, while the other diseases arise from different pathogens. Understanding these classifications is essential in the field of infectious diseases and impacts treatment and prevention strategies.
