Jaundice is a common summer disease mainly caused due to the consumption of contaminated water. Here's how you can stay protected against it this season.

Jaundice is one of the diseases that are more common in summers. It is a condition in which the skin, sclera (whites of the eyes) and mucous membranes turn yellow. The yellow colour is because of the high levels of bilirubin, a waste material found in the bloodstream.

Normally, jaundice is a sign of other underlying conditions associated with the liver, gallbladder, or pancreas. It may result from an inflamed liver, obstructed bile duct or other underlying conditions that cause overproduction of bilirubin or prevent the liver from getting rid of it. When there is too much bilirubin, it can leak into the surrounding tissues and cause the yellow colour in the skin and eyes.

Infections of the liver by viruses (hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E) can also cause jaundice. Of these, hepatitis A and hepatitis E viruses are commonly acquired through consumption of contaminated water. These viruses are transmitted by the faeces-oral route. You may get them if you ingest food or water contaminated with the faeces of an infected person. The viral infection may impair the ability of the liver to secrete bilirubin, and lead to jaundice. Waterborne jaundice is commonly called as acute viral hepatitis.
