Waterborne diseases are caused by micro-organisms that make their way into our body when contaminated water or food is consumed. They are the leading cause of diarrhoea and complications arising out of this, in third world countries. Diarrhoea is a condition in which watery faeces is discharged frequently and sometimes it contains blood or mucous.

Natural calamities like earthquakes, floods, and cyclones cause changes in pathogenic patterns which bring newer strains of microbes and trigger these diseases. Also, poor maintenance of municipal water lines can lead to contamination of drinking water from raw sewage. Finally, these diseases can spread from water or food contaminated by animal waste.

Prevention

The best part about water-borne diseases, as any gastroenterologist or gastrointestinal surgeon will tell you, is that they are completely preventable. By exercising care and caution, you can safeguard yourself and your family from the consequences of these diseases. Here are some tips. For more information, contact a gastroenterologist at a reputed hospital.

• If you do not have access to safe drinking water, please install a water purifier at home. If this is not possible, boil the water used for drinking and cooking.
• Keep the house in general and the toilets clean. Flush properly and use disinfectants regularly.
• At a personal level, one must follow sanitary hygiene with discipline. Wash your hands with soap after using the toilet and before touching any food items.
• Educate friends and family on the dangers of water-borne diseases.
• Infants should be exclusively breastfed for the first six months of life to prevent diarrhoea in them.
• Parents and caretakers of children should wash their hands with soap after changing diapers and as often as possible in a day.
• Caretakers of elders with incontinence issues should wash their hands with soap as often as possible in a day.
• If water stays stagnant near your house after rains, contact your municipal authorities to rectify the problem.
• Avoid eating street food whenever there is an outbreak of cholera, typhoid, dysentery or diarrhoea.
• Vegetables and fruits must be washed with a dilute vinegar solution at home and refrigerated before cooking.
• Purchase meat from hygienically maintained stalls and refrigerate them after bringing home. Do not consume items made of raw meat (example – sushi).
• While eating street food, consume items that are hot or heated and avoid those at ambient temperature. Also, such hot items should not be kept outside, open to the air. They must be covered always or prepared in front of you.
