How many waterborne disease illnesses are estimated to occur worldwide each year?

The estimate of 250 million waterborne disease illnesses occurring worldwide each year highlights the significant public health challenge posed by contaminated water sources. Waterborne diseases, which can include illnesses such as cholera, giardiasis, and other gastrointestinal infections, have severe implications for health systems, particularly in areas with inadequate sanitation and limited access to clean drinking water.

This figure underscores the need for effective water treatment, sanitation measures, and public health education to reduce the incidence of these diseases. By recognizing the magnitude of the issue, public health officials and policymakers can prioritize interventions and resources to tackle waterborne disease prevention and improve water quality on a global scale.
