Answers
Cholera is an infectious disease that leads to watery diarrhoea, which further causes dehydration and even death if not treated on time. It happens when you eat or drink water contaminated with a bacterium called Vibrio cholera.Over the last 5 years in India, Dengue cases have gone up by eight times and cholera cases, seven times. A recent report stated that every year, approximately 1,18,093 people suffer from diarrhoea. The disease is highly common in places with poor sanitation, crowds, famine and war. Common locations include parts of Africa, South Asia and Latin America. So if you are travelling to any of these areas with your family, being aware of the following information is important.Causes of Cholera:
Vibrio cholera, the bacterium that is solely responsible for cholera, is generally found in food or water contaminated by feces from a person who has the infection.Common sources are:
Municipal water supplies
Ice made of municipal water
Food and drinks sold at street stalls
Vegetables grown in water contaminated with human waste
Raw or uncooked fish or seafood caught from waters that are polluted with sewageWhen a person eats that contaminated food or drinks the water, the bacteria tend to release a toxin in the intestines that cause severe diarrhoea.
There are fewer chances of you getting affected by cholera simply from casual contact with an infected person.Symptoms of cholera:
Symptoms of cholera can start within a few hours or even after 5 days after the infection. Most of the time symptoms are mild. However, sometimes they are very serious. About one in 20 infected people experience severe watery diarrhoea accompanied with vomiting, which can instantly cause dehydration. Although, majority of people have minimal to no symptoms, they still can spread the infection.
