Eliminating or reducing the waterbird population from recreational areas is difficult. This requires capturing, treating, and releasing the birds individually. It’s possible to treat waterfowl with an anti-worm drug to reduce the parasite population. The authors also suggest that a warming climate may tend to increase the incidence of swimmer’s rash.Ĭontrol efforts are not easy. Knowledge of the particular species involved, for example, will help target control efforts. The 2015 review article in Clinical Microbial Reviews suggests that more research is needed to help in control measures. Temperature and sunlight also play a role in the parasite’s life cycle.The parasite’s life cycle depends on having both infected birds or animals and snails present.Waterfowl are migratory and may pick up the parasite around the world.There are also different species of the parasite itself, each with specific attributes.
There are almost 100 species that can carry the parasite.How long the water remains infective depends on many factors: After the rash is gone, you may have a pigmented spot where the pimple was for a few weeks. Most of the time, the rash clears up on its own without complications. Based on reports in the last decade, a 2015 review article calls swimmer’s itch an emerging disease, responsible for the majority of dermatitis outbreaks worldwide. There are few statistics kept on its occurrence. Swimmer’s itch is a common summer ailment around the world. What’s the outlook for cercarial dermatitis? If you swim or wade in infested water, some of these parasitic worms may mistakenly land on your skin. These larvae live only for about 24 hours and hunt for a proper host to continue their life cycle. These tiny larvae, known as cercariae, swim around looking for waterfowl or water animals to begin the cycle again. After the parasite infects the snail and develops in it, the snail excretes a second form of parasitic larvae into the water. When the parasite’s eggs hatch in the water, the larvae swim around trying to find their second host, a species of snail. The birds or animals then pass the eggs of the parasite into the water through their feces. In its life cycle, the parasitic worm infects the blood of waterfowl and some animals that live near the water. You just happen to be there swimming or wading when the parasite, in its infective stage, is searching for its natural host. Its normal life cycle is from waterfowl or water animal to snail and back again. It accidently attaches to you and other humans while it’s looking for a water bird or another animal host. Cercarial dermatitis is caused by a parasitic worm that burrows into your skin.
