Symptoms of schistosomiasis can vary based on the species and the stage of infection. Initially, individuals may experience a rash or itchy skin. Acute symptoms, known as Katayama fever, include fever, chills, muscle aches, and cough. Chronic schistosomiasis can lead to more severe health issues such as abdominal pain, diarrhea, blood in the stool or urine, and organ damage. In some cases, it can cause long-term consequences like bladder cancer or liver fibrosis.
