Which statement is false regarding shigellosis?

The statement asserting that a large number of organisms are needed to produce infection is false regarding shigellosis. In fact, Shigella is highly infectious, and only a small number of organisms (as few as 10 to 100) can cause illness. This high infectivity underscores why shigellosis is a significant concern, especially in areas where sanitation is poor.

Transmission of shigellosis occurs through the fecal-oral route, meaning individuals can become infected by ingesting food or water contaminated with feces from an infected person. This highlights the importance of proper hygiene practices to control the spread of the disease.

Acute bloody diarrhea is indeed a clinical sign of shigellosis, reflecting the pathogenic nature of Shigella, which can cause severe intestinal inflammation and ulceration. Recognizing this symptom is crucial for diagnosis and treatment.

Regarding reservoirs, while humans are the primary reservoir for Shigella, it is not accurate to state that only nonhuman primates are significant reservoirs. While nonhuman primates can harbor Shigella, they are not the only animals associated with the transmission of the disease. Thus, the focus is predominantly on human transmission, emphasizing the importance of understanding human behavior in the spread of shig
