Schistosomiasis

Overview

Schistosomiasis is a disease caused by parasitic worms that live in certain types of freshwater snails. People can get infected when they come into contact with contaminated water containing these parasites. The parasites enter the body by burrowing through the skin and then move to the blood vessels around the intestines or bladder, where they lay eggs.

Over time, these eggs can cause inflammation and damage to the organs, leading to symptoms like abdominal pain, diarrhea, and blood in the urine. In severe cases, schistosomiasis can lead to complications such as liver damage, kidney failure, and an increased risk of developing certain types of cancer. Preventing schistosomiasis involves avoiding contact with freshwater sources where the parasites are present, as well as treating infected individuals with medications to kill the worms.

People living in poverty and without proper healthcare facilities are more vulnerable to the disease, as they may not have access to preventive measures or treatment. Overall, anyone living in endemic areas or coming into contact with contaminated water sources is at risk of being affected by schistosomiasis.

Types of Schistosomiasis

Schistosomiasis is a disease caused by parasitic worms that belong to the genus Schistosoma. There are several types of schistosomiasis, namely Schistosoma mansoni, Schistosoma haematobium, and Schistosoma japonicum. Each type of the disease is transmitted through contact with contaminated freshwater sources where the parasites live.

Schistosoma mansoni primarily occurs in Africa and South America, and it causes intestinal schistosomiasis. Schistosoma haematobium is common in Africa and the Middle East, leading to urinary schistosomiasis. Lastly, Schistosoma japonicum is predominantly found in parts of Asia, causing intestinal schistosomiasis. Despite their geographical differences, all types of schistosomiasis share similar symptoms such as fever, abdominal pain, and blood in the urine or stool.

Diagnostic of Schistosomiasis

Schistosomiasis is diagnosed by examining a sample of stool or urine under a microscope to look for the eggs of the parasitic worms that cause the disease. Sometimes a blood test can also be done to check for antibodies that the body produces in response to the infection. In more advanced cases, imaging tests like ultrasound or MRI may be used to look for signs of damage in organs caused by the worms. Diagnosis of schistosomiasis is important because early detection can lead to more effective treatment and preventing complications.

Treatment of Schistosomiasis

Schistosomiasis is usually treated with medications called praziquantel. These medications work by killing the parasites that cause the disease. The treatment is typically given as a single dose, but in some cases, multiple doses may be needed.
