Which symptom is NOT associated with cholera?

Cholera, caused by the bacterium Vibrio cholerae, is primarily characterized by the rapid onset of severe watery diarrhea and can lead to significant fluid loss, resulting in several associated symptoms. Severe dehydration, abdominal distension, and hypotension are all common manifestations of choleral infection.

Severe dehydration occurs due to the loss of large volumes of fluid in the stool, leading to a decrease in body fluid volume. Abdominal distension may occur as a result of intestinal inflammation or the large volume of watery stool and gas buildup. Hypotension can develop due to the depletion of fluids and subsequent reduction in blood volume, which can compromise perfusion to vital organs.

Acute kidney injury is not a direct symptom of choleral infection. While dehydration can lead to changes in kidney function, acute kidney injury specifically refers to a more significant and distinct condition that involves rapid loss of kidney function. In cholera, the acute change in renal function can occur due to the profound dehydration and electrolyte imbalance caused by the diarrhea but is not an inherent symptom associated with the disease itself. Thus, the correct answer highlights that acute kidney injury, while possible as a consequence of severe fluid loss, is not a classic symptom directly linked to cholera.
