What Are Water Borne Diseases?

  • Diseases caused by drinking water or having food, that is contaminated by pathogenic microorganisms like bacteria, protozoa and viruses, parasites and the presence of toxins.
  • Waterborne disease outbreaks are the most common cause of illness in developing countries.

Disease Transmission

  • Contamination of drinking water sources from infected animal and human wastes and inadequate sanitation are the primary pathways for disease transmission.
  • Severe precipitation events, leading to flooding and causes outbursts of waterborne diseases.
  • Warm and moist weather enhance growth and spread of pathogenic bacteria.
