What is Giardia?

Giardia is a microscopic parasite that lives in the intestines of infected people or animals. It is commonly transmitted by contaminated water sources, often through fecal-oral contact. The infection it causes, known as giardiasis, is frequently characterized by diarrhea, abdominal cramps, and fatigue. Symptoms can last for up to 45 days, often leading to dehydration, malnourishment, and other health complications.

Social Effects

Limited access to clean drinking water can have a significant social impact, as it can lead to decreased productivity, heightened rates of school absenteeism, and diminished quality of life. In high-prevalence areas, members of the community may feel ashamed or stigmatized, leading to decreased social participation. In addition, many families in developing countries lack educational resources to effectively fight and prevent giardiasis, resulting in a prolonged, cyclical cycle of infection and reinfection.

Economic Impact

Giardiasis has a measurable economic impact in both high- and low-income countries. In high-income countries, costs associated with water treatment, medical care, and lost productivity are considerable, while in low-income settings, these costs may not be easily calculated. In both settings, though, the economic burden of giardiasis can be considerable, as families lack resources for medical care and water treatment, leading to even greater losses in earnings and quality of life.
