Which parasitic infection can lead to a "winter's itch"?

Winter's itch, often characterized by pruritic (itchy) skin conditions, is primarily associated with schistosomiasis, especially in areas where the schistosome parasites infect the skin. Schistosoma species, particularly Schistosoma mansoni and Schistosoma haematobium, can cause swimmer's itch, a similar type of dermatitis, when cercariae penetrate the skin. This phenomenon is most common in stagnant waters where these parasites are present.

In cases of exposure to contaminated water, individuals may experience rashes and itchy skin, resembling what is commonly referred to as winter's itch. While the other parasitic infections listed may have their own distinct symptoms and complications, they do not typically result in the pruritic skin conditions associated with schistosomiasis. Understanding the relationship between schistosomiasis and skin manifestations can aid in diagnosis and management of this parasitic infection.
