Shiff et al. [5] found that the proportion of egg-positive individuals falls progressively with age and is a feature in populations with lifelong exposure to the parasite. [hindawi.com]
As prevalence falls, diagnostics can identify high transmission areas, monitor disease trends, and guide evidence-based control strategies. [mmj.mw]
Of the 16 species of schistosomes known to infest man or animals, the 5 principal ones that infect man fall into three groups that are characterized by the type of egg produced: (a) eggs with a lateral spine, e.g., S. mansoni; (b) eggs with a terminal [community.vanguardngr.com]

Complications (for example, hepatomegaly or enlarged liver and bladder cancer) related to the disease are thought to occur due to long-term exposure to the highly antigenic eggs. [medicinenet.com]
In addition, hepatomegaly is a common symptom in the early stages of the disease and is often accompanied by a fluid accumulation in the peritoneal cavity and an increase of pressure in the intestinal vessels. [dovepress.com]

Symptoms and signs include dysuria, urgency, terminal microscopic and gross hematuria, secondary urinary tract infections, and nonspecific pelvic pain. Chronic urinary carriage and bacteremia with salmonella can occur. [meddean.luc.edu]
The common presenting symptoms of carcinoma ol the bladder were haematuria, pyuria, hypogastric pain, dysuria and frequency. More than a third of the patients had palpable suprapubic masses on admission. The tumours were often large and sessile. [erepository.uonbi.ac.ke]

Treatment
Control is reliant on annual mass-treatment programmes, with little prospect of an anti-infection vaccine. [findaphd.com]
Each cohort will be examined before treatment and 2, 6 and 18 months after treatment. The study will be carried out in 4 primary schools; two from Machava J area and two from Costa do Sol area. [clinicaltrials.gov]

The prognosis of schistosomiasisassociated PAH is not well understood and is likely very similar to that of idiopathic PAH. [phassociation.org]
What is the prognosis (outcome) for schistosomiasis? Early antiparasitic treatment, especially with acute schistosomiasis, may allow people to recover completely without developing chronic disease. [medicinenet.com]
If someone is also infected with malaria, HIV, or hepatitis, there is a worse prognosis. Can schistosomiasis be prevented? People who travel to areas affected by schistosomiasis should avoid exposure to fresh water that is likely to be contaminated. [patient.info]
