A similar life cycle occurs with Opisthorchis viverrini, which is found in South East Asia and can infect the liver of humans, causing Cholangiocarcinoma (bile duct cancer). Schistosomes, which cause the devastating tropical disease bilharzia, also belong to this group. [27] Adults range between 0.2 mm (0.0079 in) and 6 mm (0.24 in) in length.
The rash can occur between the first few hours and a week after exposure, and they normally resolve on their own in around 7–10 days. [21] [19] For human schistosomiasis, a similar type of dermatitis called "swimmer's itch" can also be caused by cercariae from animal trematodes that often infect birds.
Infection on the skin of the feet may cause athlete's foot and in the groin, jock itch. Involvement of the nails is termed onychomycosis. Animals including dogs and cats can also be affected by ringworm, and the disease can be transmitted between animals and humans, making it a zoonotic disease. Specific signs can be:
What it looks like: The most recognizable reaction on this list is the bullseye rash—a large, red, target-like rash that signals the early stages of Lyme disease from the bite of an infected ...
Lupus is an autoimmune disease that causes a red scaly rash on the cheeks and nose, says Dr. Parikh. In particular, the rash is characterized as looking like a butterfly across the face, she explains.
Schistosoma mansoni is a water-borne parasite of humans, and belongs to the group of blood flukes (Schistosoma). The adult lives in the blood vessels (mesenteric veins) near the human intestine. It causes intestinal schistosomiasis (similar to S. japonicum, S. mekongi, S. guineensis, and S. intercalatum). Clinical symptoms are caused by the eggs.
A venomous spider bite (like this brown recluse bite) can cause a red or purplish rash radiating from the site of the bite. There are only a few species of spiders in the U.S. that can bite humans.
Swimmer's itch was known to exist as early as the 19th century, but it was not until 1928 that a biologist found that the dermatitis was caused by the larval stage of a group of flatworm parasites in the family Schistosomatidae. [7] The genera most commonly associated with swimmer's itch in humans are Trichobilharzia [4] and Gigantobilharzia.
