However, some general approaches that may be effective in treating flukes include:
- 1. Treating the underlying cause of the fluke infection, such as antibiotic treatment for a bacterial infection or treatment for worms if the patient is symptomatic.
- 2. Treating the symptoms of the fluke infection, such as antibiotics for fever or pain relief.
- 3. Treating the fluke itself with a prescribed antifluke medication.

How do you know if you have lung fluke?

Then they pass through the diaphragm, and invade the lungs. There, they develop into adults and produce eggs. Adults can live 20 years if not treated. The flukes may also go to the brain, liver, lymph nodes, skin, or spinal cord where they form cysts and produce eggs.
Can flukes go away?
Treatment. The first step to treat flukes is to dip the fish for five to ten minutes in freshwater.

How do humans get paragonimiasis?
Paragonimiasis is caused by lung flukes of the genus Paragonimus. Humans acquire the disease by ingesting their larvae in undercooked crustaceans. Thereafter, larvae enter the peritoneal cavity and migrate to the lungs. Further migration of the worms through the foramina of the skull base to the CNS may occur and is characterized by meningitis, granulomatous or calcified parenchymal brain lesions, and cerebral hemorrhages. The meningitic form of the disease course with focal signs related to cerebral infarcts caused by Paragonimus-induced endarteritis. Parenchymal brain lesions produce seizures, focal signs, and intracranial hypertension. Cerebral hemorrhages may occur along tracts of larvae migration or as the result of the necrotizing vasculitis that develops during early granuloma formation. Diagnosis is suggested by the presence of specific antibodies in CSF or by neuroimaging findings of confluent calcifications located in the temporal and occipital lobes that resemble ‘soap bubbles.’ Support for the diagnosis is provided by demonstration of Paragonimus eggs in the sputum. Therapy includes praziquantel and corticosteroids.
What is the respiratory fluke?
Epidemiology#N#The lung fluke , Paragonimus westermani, is found throughout eastern Asia and infects a wide variety of mammalian reservoir hosts. Numerous fresh water crustaceans such as crabs and crayfish serve as intermediate hosts and infection occurs when these are eaten raw or lightly cooked. Several other members of the Paragonimus genus routinely cause human infection, mostly in areas of eastern Asia, central and western Africa, and Latin America. A cluster of cases of North American paragonimiasis, caused by Paragonimus kellicotti, and associated with ingestion of raw crayfish has been recently described in the mid-west USA.21
How to diagnose paragonimus?
Diagnosis of human paragonimiasis is based on clinical features, as well as on laboratory tests. Definitive diagnosis is established by presentation of Paragon imus eggs in the sputa and/or faeces by microscopic examination. Supporting methods include chest X-ray ( Fig. 11.8) and immunological tests. Reliable serological tests have been applied for immunodiagnosis of human paragonimiasis; these include ELISA and immunoblotting-based methods ( Maleewong, 2003 ). Immunoblotting for the detection of IgG4 antibody to ES products of adult P. heterotremus provides a sensitive and specific test ( Wongkham et al., 2005 ). Recently, a recombinant protein of a P. westermani egg antigen was tested as an ELISA antigen ( Lee et al., 2007 ). This assay offered a highly sensitive and specific assay for serodiagnosis. A PCR for detection of DNA from Paragonimus eggs in faeces or sputa has potential in clinical epidemiological studies ( Intapan et al., 2005 ).
