what were the symptoms of cholera

Symptoms

Cholera is a well-known disease caused by intestinal infection with the toxin-producing bacteria Vibrio cholerae. This potentially fatal diarrheal disease results in large volumes of watery stool, causing rapid dehydration that can progress to hypovolemic shock and metabolic acidosis. The case-fatality ratio is up to half in vulnerable groups during outbreaks but can be under 1% if properly ...

Causes

When untreated, Cholera can be very destructive, killing in practically no time. Intense diarrhoeal disease is brought about by eating or drinking food or water that is debased with the bacterium “Vibrio cholera” and is perhaps the most lethal illness in emerging nations.

Prevention

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

In 1831, most physicians believed cholera to be a nonspecific, noncontagious miasmatic condition that favored the morally and physically predisposed. By the end of the 19th century, although the miasmatic interpretation still had influence, cholera was primarily understood to be a specific contagious disease caused by a particular microscopic organism.
