Trematodiases that infects the lung, liver and intestine are classified as neglected tropical diseases by the World Health Organisation.
Neglected tropical diseases are made up of bacterial, parasitic and viral infections that negatively impact the development of children, pregnancy and economic outcomes of developing countries.

Changes in population numbers, food distribution channels, poverty and health education programs contribute to the fluctuating epidemiological patterns.
Social, ecological and economical factors also change distribution patterns globally.
Factors such as rainfall, pollution, climate, vegetation, water temperature and quality change the interactions between trematodes and their hosts.
The expansion of aquaculture production and irrigation systems has also changed the spread of the disease.
In areas where water is not sufficiently sanitised, infection rates have increased.

The World Health Organisation declares that there are approximately 200000 cases per year, leading to over 7000 deaths.
The highest number of foodborne trematodiases cases and the highest disease burden was recorded in East and Southeast Asia in 2019.
In northeast Thailand, O. viverrini which is carcinogenic is present in high numbers, where over 20000 lives are lost a year due to cholangiocarcinoma caused by the trematode.

Clonorchis sinensis and Opisthorchis viverrini are two species which can cause trematodiases that infects the liver.
These are more prevalent in males than females, and more common in adults than children.
F. hepatica, a species of liver flukes, have a higher incidence rate in children and females, with a higher number of cases of lung fluke and intestinal trematodiases in children.
Cases of liver and lung fluke trematodiases are high in numbers due to the amount of time the trematode can live in host organisms and increased chances of reinfection.

Increase in travel and increase in popularity of traditional dishes such as raw oysters, crab meat, pickled seafood and other undercooked aquatic plants has also contributed to the rise in cases of trematodiases.
The Global Burden of Disease Study carried out in 2016 estimated that approximately 75 million people were impacted by trematodiases and that there were around 2 million disability-adjusted life years that were affected and lost to the disease, due to damage that was caused by the infection.
