Atopic Dermatitis Caused By Schistosomiasis (schistosomiasis)

Schistosomiasis is an acute and short-lived skin disease caused by the larvae of the parasite in the blood vessels of animals and rodents.
The development cycle of the schistosomiasis
The life cycle of schistosomiasis and the process of invading the human body
Flukes in the feces out, meet the hatchery environment into larvae and live in water clinging to aquatic plants and snail. Here they develop into spore 1, then follicle 2, caudal fin forked in two. The tail larvae split off snails and swam freely in the water. When people bathe in the river, swim in the sea, or work in contact with water, the larvae burrow through the skin and get trapped here, causing quite a special case of dermatitis

.
Areas and subjects can be infected with schistosomiasis
Schistosomiasis is ubiquitous, with about 25 types of tail larvae living in fresh water and 4 types in salt water. In the North of our country, as reported at the Conference of Parasites and Malaria in 1960, tapeworm has caused dermatitis in farmers cultivating ducks' fields by Trichobilharzia spp. The intermediate host is the Radix ovata snail In the south of the country today, ducks' farmers graze a lot in the provinces of the Mekong Delta, with a high likelihood of dermatitis
Manifestations of the body when infected with schistosomiasis
For the first few hours after the larvae enter the skin, the patient experiences intense itching, skin edema and rash. Afterwards, the red spots thicken into papules; maximum on days 2 and 3.



. This is just an allergic reaction on the skin. Prolonged itching causes severe scratching of the patient, leading to complications of scratching the skin, ulcers and skin infections.
Diagnosis of schistosomiasis
Based on your history of exposure to waters where caudal larvae have been infected
Based on the time when the doctor asks about the disease, and the actual damage on the skin
Urine test, sediment scan to find tapeworm larvae
Treatment of schistosomiasis
Using medicine to kill helminths
Combining medication to treat manifestations of dermatitis
Supportive drugs enhance resistance to the skin and body
Use antibiotics when needed
Prevention of schistosomiasis
Removal of snails around the area of beaches with copper sulfate, copper carbonate, or pentachlorphenate, combined with the clearance of aquatic plants.
Dry the body as soon as the shower is finished
