Frequency of geohelminths
in public squares in Pelotas, RS, Brazil.
Soil-transmitted helminths (STH), also known as geohelminths
[1, 2], are "intestinal worms infecting humans that are transmitted through contaminated soil." The main soil-transmitted helminthiases include infections with roundworm (Ascaris lumbricoides), hookworm (Ancylostoma duodenale and Necator americanus), and whipworm (Trichuris trichiura) .
Immunological studies show that the impact of geohelminths
and malaria parasites is intensified when they coexist [4, 5].

(1) The WHO further estimated that schistosome infections and geohelminths
accounts for over 40% of the world tropical disease burden with the exclusion of malaria.
Both dog and cat roundworms are mildly zoonotic geohelminths
. (19) The eggs are environmentally stable and infectious in soil contaminated by animal feces.
Keeping in view these public health problems this study was conducted with the objective to assess the frequency of intestinal geohelminths
and other intestinal parasitic infections.
