Study Notes
Giardiasis Introduction
- Giardia duodenalis is a protozoan parasite causing diarrhea, potentially in sporadic or epidemic forms.
- Giardiasis is a significant cause of waterborne/foodborne illness, daycare outbreaks, and traveler's illness.
Giardiasis Epidemiology
- Globally Present: Giardia duodenalis infection occurs worldwide.
- High-Risk Groups: Infants, young children, internationally adopted children, travelers, immunocompromised individuals, and cystic fibrosis patients are at higher risk.
-
Sporadic Giardiasis Risk Factors (US Study):
- Male-male sexual behavior (aOR 45.7)
- International travel (aOR 13.9)
- Drinking water from rivers, lakes, streams, or springs (aOR 6.5)
- Swimming in natural water bodies (aOR 3.3)
- Contact with children in diapers (aOR 1.6)
- Antibiotic use (aOR 2.5)
- Presence of a chronic gastrointestinal condition (aOR 1.8)
- High Incidence: Giardiasis is more prevalent in regions with poor sanitation and inadequate water treatment.
