Giardiasis is a worldwide infection. It is the most common cause of parasitic diarrhea with a prevalence that may be as high as 20% to 40% in settings of poor sanitation. In the USA, the incidence of giardiasis is thought to be decreasing from 20 to 25 cases per 100,000 individuals between 1990 and 1998 to approximately 4 to 5 cases per 100,000 individuals in 2012. Children, particularly < 5 years of age, are more frequently affected with giardiasis than adults. There is no gender or racial predilection for the development of giardiasis. | |||

Overview
Giardiasis is a worldwide infection. It is the most common cause of parasitic diarrhea with a prevalence that may be as high as 20% to 40% in settings of poor sanitation. In the USA, the incidence of giardiasis is thought to be decreasing from 20 to 25 cases per 100,000 individuals between 1990 and 1998 to approximately 4 to 5 cases per 100,000 individuals in 2012. Children, particularly < 5 years of age, are more frequently affected with giardiasis than adults. There is no gender or racial predilection for the development of giardiasis.
Epidemiology and Demographics
Incidence and Prevalence
- Giardiasis is a worldwide infection. It is the most common cause of parasitic diarrhea.[1]
- In the USA, the incidence of giardiasis is thought to be decreaesing. In 2012, the incidence of giardiasis was approximately 4 to 5 cases per 100,000 individuals in the USA, compared with 20 to 25 cases per 100,000 individuals between 1990 and 1998.[2][3]
- The prevalence of giardiasis is highly variable. In settings with poor sanitation, the prevalence of giardiasis may be as high as 40%.[1]
Age
- Children, particularly < 5 years of age, are more frequently affected with giardiasis than adults.
Gender
- There is no gender predilection for the development of giardiasis.
Race
- There is no racial predilection for the development of giardiasis.
Developed Countries
- In developed countries, the incidence of giardiasis is decreasing.
- The decrease is attributed to improved sanitation and available resources.
Developing Countries
- The majority of cases of giardiasis occur in developing countries, where the prevalence may be as high as 20% to 40% in settings of poor sanitation.[1]
