The news is rife with reports of the ever increasing cases of cholera in the city this year. With the numbers increasing alarmingly state health authorities are flummoxed with the sudden trend. So how is cholera caused? How does it spread? Can it be prevented? How is it treated? Cholera is an acute infectious disease caused due to a bacteria called Vibrio cholerae. The bacteria has the ability to produce toxins within the human body which leads to painless watery diarrhoea also called ‘rice water stools’ because of its appearance. In some cases patients might also have vomiting associated with the disease.
