Public Health Faculty Publishes Article about Giardia

Brenden Bedard, MPH, Adjunct Lecturer, Department of Public Health and Health Education, published an article about Giardia in volume 3 of the International Journal of Migration, Health and Social Care

Objective: The objective of this analysis was to determine the morbidity of Giardia in Monroe County, New York attributed to refugees, foreign adoptees and immigrants, and to examine factors related to asymptomatic Giardia infection.


A retrospective epidemiological analysis was conducted of Giardia case investigations submitted to the New York State Department of Health (NYSDOH) on the Communicable Disease Electronic Surveillance System (CDESS), between January 1, 2003 and December 31, 2013 from Monroe County Department of Public Health. Univariate and multivariate logistic regression models were used to assess odds for asymptomatic Giardia.


Of the 1,221 Giardia cases reported in Monroe County during that time, 38% (N = 467) were refugees, 6% (N=77) were foreign adoptees, and 1.4% (N=17) were immigrants. Ninety-five percent (95%) of the refugees and 89% of the adoptees/immigrants were asymptomatic, compared to 15% of the non-refugee/adoptee/immigrant cases. Unadjusted odds for asymptomatic infection were 113.4 (95% CI: 70.6-183.7) for refugees, and 45.6 (95%CI: 22.9-91) for adoptees/immigrants.


This study demonstrates the importance of routine screening for Giardia during refugees’ initial health assessment.
