Overview

Cholera infection can cause a severe diarrheal disease with acute and substantial loss of water and electrolytes.[1] The incubation period is very short (2 hours to 5 days), which allows the number of cases in an area to rise extremely quickly. Delayed initiation of oral rehydration therapy or inadequate rehydration may lead to hypotension and electrolyte imbalance (mostly hypokalemia). If dehydration is left untreated, it may lead to hypotension, which can result in renal failure, hypovolemic shock, coma, and death. If hypokalemia is left untreated, it can lead to nephropathy and focal myocardial necrosis. Among the children, hypoglycemia is common and can lead to seizures.[2] If patients with cholera are treated quickly and properly, the mortality rate is less than 1%. However, when cholera is left untreated, the mortality rate rises to 50–60%.[3][4]

Natural history, complications, and prognosis

Natural history

Cholera infection can cause a severe diarrheal disease with acute and substantial loss of water and electrolytes.[1] The incubation period is very short (2 hours to 5 days), which allows the number of cases in an area to rise extremely quickly. Delayed initiation of oral rehydration therapy or inadequate rehydration may lead to hypotension and electrolyte imbalance (mostly hypokalemia). If dehydration is left untreated, it may lead to hypotension, which can result in renal failure, hypovolemic shock, coma, and death. If hypokalemia is left untreated, it can lead to nephropathy and focal myocardial necrosis. Among the children, hypoglycemia is common and can lead to seizures.[2] If patients with cholera are treated quickly and properly, the mortality rate is less than 1%. However, when cholera is left untreated, the mortality rate rises to 50–60%.[3][5]

Complications

Major complications of cholera include:[6][2]

Prognosis

If people with cholera are treated quickly and adequately, the mortality rate is less than 1%. However, if cholera is left untreated, the mortality rate rises to 50–60%.[3][7]
