Symptoms of Schistosomiasis
Schistosomiasis, also known as bilharzia, is a parasitic disease caused by Schistosoma worms. It is a significant public health issue, particularly in tropical and subtropical regions, affecting millions of people worldwide. The disease is spread through freshwater contaminated with the larvae of the parasite, which infect humans upon contact.
Understanding the symptoms, causes, and treatment of schistosomiasis is crucial for early detection and prevention. In this article, we will explore the symptoms of schistosomiasis in a simple, easy-to-understand way.
Causes of Schistosomiasis: Symptoms of Schistosomiasis
Schistosomiasis is caused by parasitic worms called Schistosoma. People become infected when they come into contact with contaminated freshwater that contains the larvae of the parasite. These parasites are released into the water by freshwater snails, which act as intermediate hosts.
The larvae penetrate the skin when people swim, bathe, wash, or come into contact with contaminated water. Once inside the body, the larvae mature into adult worms, which live in the blood vessels. These adult worms lay eggs, and some of the eggs are passed out of the body through urine or feces, continuing the cycle when they reach water sources again.
Symptoms of Schistosomiasis
Schistosomiasis symptoms vary depending on the stage of infection—acute or chronic. The symptoms may not appear immediately after infection, but over time, the body reacts to the eggs produced by the parasites.
Early Symptoms (Acute Schistosomiasis)
In the early stages of infection, when the parasites first enter the body, some people may experience mild symptoms. These early symptoms, known as swimmer’s itch or Katayama fever, occur within days or weeks of contact with contaminated water and may include:
- Itchy rash: The first sign of infection may be an itchy, red rash where the parasites entered the skin. This is often called swimmer’s itch and usually appears within a few days of exposure.
- Fever: A mild to high fever may develop within a few weeks of infection.
- Cough: Some individuals experience a dry cough as the parasite migrates through the body.
- Muscle pain: Generalized body aches, muscle pain, or discomfort can occur as the immune system reacts to the parasite.
- Diarrhea: Some individuals may experience diarrhea or abdominal discomfort in the early stages of infection.
- Fatigue: Weakness and tiredness are common symptoms as the body tries to fight the infection.
- Swollen glands: In some cases, people may develop swollen lymph nodes due to the body’s immune response to the parasite.
These early symptoms are often mild and can be mistaken for other common illnesses. If left untreated, the infection can progress to more serious, long-term health problems.
Chronic Schistosomiasis Symptoms
If schistosomiasis is not treated in its early stages, it can progress to a chronic form. This occurs when the body starts to react to the eggs produced by the parasites. The symptoms of chronic schistosomiasis can vary depending on the organs affected, and they may develop months or even years after the initial infection.
- Blood in urine: One of the most common signs of schistosomiasis is blood in the urine, particularly in cases caused by Schistosoma haematobium, which affects the urinary system.
- Blood in stool: For individuals infected with other types of Schistosoma worms, blood may appear in the stool.
- Abdominal pain: Chronic schistosomiasis can cause ongoing pain and discomfort in the abdomen.
- Enlarged liver or spleen: In some cases, the infection may cause the liver or spleen to become enlarged.
- Anemia: Ongoing blood loss due to the infection can lead to anemia, causing symptoms like fatigue, weakness, and pale skin.
- Difficulty urinating: Some individuals may experience pain or difficulty when urinating due to damage to the urinary tract.
- Intestinal problems: Long-term infection can cause damage to the intestines, leading to chronic diarrhea, pain, or blockage.
Without treatment, schistosomiasis can cause serious complications, including liver damage, kidney failure, bladder cancer, and infertility.
When to Seek Medical Help
If you have been in contact with freshwater in regions where schistosomiasis is common and begin to experience any of the symptoms mentioned above, it’s important to seek medical attention as soon as possible. Early diagnosis and treatment can prevent the infection from progressing to more serious stages.

Treatment for Schistosomiasis
The treatment for schistosomiasis involves taking an antiparasitic medication called praziquantel. This medication is highly effective in killing the adult worms and stopping the disease from progressing. Treatment is most effective when started early, so it is crucial to seek medical attention as soon as possible.
In addition to medication, supportive care may be needed to manage any symptoms or complications caused by the infection, such as anemia or organ damage.
Preventing Schistosomiasis
The best way to prevent schistosomiasis is to avoid contact with contaminated freshwater in areas where the disease is common. Some key prevention tips include:
- Avoid swimming or wading in freshwater lakes, rivers, or ponds in endemic areas.
- Drink only safe, clean water.
- Use protective footwear and clothing if you must enter potentially contaminated water.
- Educate others about the risks of schistosomiasis and the importance of proper sanitation.
Schistosomiasis is a serious parasitic disease, but with early detection and treatment, it can be effectively managed. Knowing the symptoms and causes can help you recognize the disease early and prevent complications.
