Schistosoma is a genus of parasitic flatworms responsible for schistosomiasis, a significant tropical disease affecting millions worldwide. These parasites have a complex life cycle involving freshwater snails as intermediate hosts and humans as definitive hosts, causing chronic illness and organ damage in severe cases.

Schistosoma

Parasitic flatworms, belonging to the phylum Platyhelminthes, are a diverse group of organisms that live off a host, often causing diseases in humans and animals. They exhibit complex life cycles involving multiple hosts and have developed sophisticated mechanisms to evade the host's immune system.

Parasitic Flatworms

Schistosomiasis is a parasitic disease caused by trematode flatworms of the genus Schistosoma, transmitted through contact with contaminated freshwater where specific snail hosts reside. It primarily affects populations in tropical and subtropical regions, leading to chronic illness and significant socio-economic impact if left untreated.

Chronic illness refers to a long-lasting health condition that typically persists for more than three months, often requiring ongoing medical attention and limiting daily activities. These conditions can significantly impact quality of life and may involve complex interactions between biological, psychological, and social factors.

Chronic Illness

Organ damage refers to the impairment or destruction of an organ's function due to injury, disease, or exposure to harmful substances. It can lead to significant health complications, depending on the organ affected and the extent of the damage, necessitating timely diagnosis and intervention to prevent further deterioration.
