It reveals an allergic skin reaction (Kolářová et al. 1985 Blankespoor and Reimink 1988 Loken et al. 1949 Jarcho and van Burkalow 1952 Macy 1952 Hoeffler 1974 Leedom and Short 1981 Eklu–Natey et al. In view of the real risk of people using the waters, tests on presence of the parasites in snail hosts should be included to the standard procedure of security control in bathing places.Ĭercarial dermatitis called swimmers’ itch has been listed for several years in human populations around the world (Cort 1936 Hunter et al. As indicated by the example presented, anthropogenic reservoirs create excellent conditions for Digenea species including bird schistosomes. It is worth underlining that despite the low prevalence of bird schistosomes, the high number of released cercariae was sufficient to create a real threat of swimmers’ itch in bathers.
Laboratory tests have shown that at 19 ☌ the number of bird schistosome cercariae released from snail hosts significantly exceeded the number of cercariae of other identified Digenea species. The prevalence of bird schistosomes reached 2.9 % in Planorbarius corneus, 2.8 % in Radix auricularia, and 5.9 % in Radix balthica/labiata. The larvae of bird schistosomes were recorded in both localities in 1.8 % of collected snails.
Higher prevalence of Digenea was observed in snail populations living in Water Valley (29.8 %) compared to Dzierżęcinka River (21.3 %). Snails belonging to Lymnaeidae and Planorbidae were collected at two sites: (i) part of anthropogenic reservoir (192 individuals) and (ii) the river part (37 individuals). If properly timed, these applications may prevent the annual migration of infested snails into swimming areas.After numerous reports the local press about the “stinging water” in created on the Dzierżęcinka River-Water Valley reservoir and recognizing in bathers the symptoms of swimmers’ itch, environmental study on the presence of bird schistosome larvae in snail hosts was conducted. Copper sulfate or copper carbonate materials can be applied by boat around popular bathing areas. Toweling off after swimming or wading in infested water can be very helpful in preventing rash development. What can be done to prevent the spread of swimmer's itch? While all cases do not require treatment, some people may seek relief by applying specific skin lotions or creams to minimize the itching. What is the treatment for swimmer's itch? Symptoms may appear within one to two hours of exposure. Repeated exposure increases a person's sensitivity to the parasite and increases the likelihood of rash development. This itching stage usually disappears within a week.Ī victim's first exposure to infested water may not result in the itchy rash. The itching will subside for 10-15 hours and may then become extremely intense. Whenever infested water is allowed to evaporate off the skin, an initial tingling sensation may be felt associated with the penetration of the parasite into the skin.
The victim may get the infection by swimming or wading in infested water and then allowing water to evaporate off the skin rather than regularly drying the skin with a towel. All age groups and both sexes can be involved, but children are most infected due to their habits of swimming or wading in the water and playing on the beach as the water evaporates from the skin. People who swim or wade in infected water may experience this itching rash.
These parasites are released from infected snails and migrate through waters including those used for recreational swimming. Swimmers itch is a skin rash caused by certain parasites of birds and mammals. Health care provider concerning appropriate care, treatment or other medical advice.
