How Do Water-Borne Diseases Affect Health?
Water-borne infections can range from mild stomach upsets to life-threatening conditions. They often cause:
Severe dehydration (due to diarrhea/vomiting)
Malnutrition (due to poor nutrient absorption)
Long-term organ damage (in cases like Hepatitis A or Leptospirosis)
Weakened immunity, making the body more prone to other infections
Children, the elderly, and those with weak immune systems are at higher risk.
How to Prevent Water-Borne Diseases
Below are the ways to prevent water-borne diseases,
1. Drink Safe Water
Boil water for at least 1 minute before drinking.
Use water purifiers (RO/UV filters).
If unsure, drink bottled water from trusted brands.
2. Maintain Hygiene
Wash hands with soap before eating and after using the toilet.
Avoid touching your face with unwashed hands.
3. Eat Clean Food
Wash fruits and vegetables thoroughly.
Avoid raw or undercooked seafood.
Eat freshly cooked food.
4. Avoid Contaminated Water Sources
Do not swim in or drink from stagnant water (ponds, lakes).
Ensure swimming pools are properly chlorinated.
5. Get Vaccinated (Where Available)
Typhoid vaccine (recommended for travelers)
Hepatitis A vaccine (especially for children)
6. Keep Surroundings Clean
Dispose of waste properly to prevent water contamination.
Ensure proper sewage systems to avoid waterlogging.
When to See a Doctor?
Seek medical help if you experience:
Persistent diarrhea or vomiting (more than 2 days)
Blood in stool
High fever with dehydration
Severe weakness or confusion
Early treatment can prevent complications. If you suspect a water-borne infection, consult a doctor immediately.
