Giardiasis, Giardiasis

Giardiasis occurs worldwide with a prevalence of 2030% in developing countries. Additionally, Giardia has a wide range of human and other mammalian hosts, thus making it very difficult to eliminate. The Centers for Disease Control and Prevention reports that in the US Giardia infects over 2.5 million people annually.

There are multiple modes of transmission including person-to-person, water-borne, and venereal. Person-to-person transmission accounts for a majority of Giardia infections and is usually associated with poor hygiene and sanitation. Water-borne transmission is common in United States Giardia epidemics, which are often associated with the ingestion of unfiltered water (contaminated). Venereal transmission happens through fecal-oral contamination. Additionally, diaper changing and inadequate hand washing are risk factors for transmission from infected children. Lastly, food-borne epidemics of Giardia have developed through the contamination of food by infected food-handlers. Pennardt, MD, Andre. "Giardiasis." EMedicine. 4 Feb. 2004. 20 Feb. 2009.

Giardiasis occurs worldwide with increased prevalence in areas with poor water treatment facilities and unsanitary conditions. The area of highest prevalence is the tropics and subtropics. Despite this, giardiasis does affect a large number of individuals living in highly developed nations with strong infrastructure and water systems. In the United States, giardiasis is the most commonly reported pathogenic protozoan disease. "Giardiasis." Giardiasis.org.

Furthermore, giardiasis is common in tourists and business travelers to developing countries, especially Mexico, Southeast Asia, western South America and Russia and the CIS. Brodsky R.E., Spencer H.C. Jr, Schultz M.G. Giardiasis in American travelers to the Soviet Union.

Using only bottled water and avoiding raw fruits and vegetables decreases risk of infection dramatically. Schrader, MD, Betsy. "Giardiasis Prevention." EMedicine Health. 10 Aug. 2005. 26 Feb. 2009 . Third, wash hands frequently, especially before eating and after using the bathroom, with soap and water for at least 20 seconds.
