Cholera

With good or adequate fluid replacement (oral or intravenous), mortality from cholera can be reduced from 40% to about 1%.[3]

Recurrence

Recurrent disease is unlikely for several years after an outbreak unless a new strain of Vibrio cholerae is introduced, due to the quality of the mucosal immune response.

HIV infection

Patients may have more serious disease and can excrete V cholerae for months after recovery. Bacteraemia has been described.[109]

Pregnant women

Risk of premature labour and miscarriage is high when untreated but falls significantly once adequate fluid resuscitation is given.
