What type of disease is Giardiasis classified as?

Giardiasis is classified as a waterborne disease because it is caused by the parasite Giardia lamblia, which is typically spread through contaminated water sources. This disease often occurs in areas where proper sanitation practices are lacking, or among individuals who consume untreated water from natural bodies such as lakes and streams. Giardiasis affects the intestinal system, leading to symptoms such as diarrhea, abdominal cramps, and nausea.

Understanding this classification is important for recognizing the prevention methods, which primarily involve ensuring access to clean drinking water and proper sanitation to eliminate the risk of contamination. The emphasis on waterborne transmission underscores the public health efforts required to control such diseases, particularly in communities prone to these risks.
