Opisthorchiasis is a parasitic infection of the bile ducts by a type of liver fluke. It is acquired by eating un- or undercooked fresh water fish from certain Asian and east European countries.
The diagnosis needs to be confirmed by laboratory testing. This involves microscopic identification of eggs in stool specimens or from duodenal aspirate. An enzyme-linked immunosorbent assay (ELISA) method for detecting antigen in the stool may also be used.
Additional diagnoses covered by SOP
* another SOP applies
Most infections are asymptomatic. In mild cases, manifestations include dyspepsia, abdominal pain, diarrhea or constipation. With infections of longer duration, the symptoms can be more severe, and hepatomegaly (enlarged liver) and malnutrition may be present. The usual incubation period is 3 to 4 weeks. Clinical onset can be based on the time of diagnosis, or backdated if relevant symptoms consistent with clinical infection have been present.
The only worsening factor is for inability to obtain appropriate clinical management.

Opisthorchiasis - Inability to obtain appropriate clinical management for opisthorchiasis Factor
Last reviewed for CCPS 13 April 1995.
Investigative Documents
Medical Report - Inability to Obtain Appropriate Clinical Management - [GQACM] Preliminary questions [8305]
8326 [6] the clinical onset of the veteran's opisthorchiasis occurred after the end of the veteran's last period of VEA service. the veteran's opisthorchiasis permanently worsened. the veteran was unable to obtain appropriate clinical management for opisthorchiasis at some time.
8329 [9] the inability to obtain appropriate clinical management for opisthorchiasis contributed to the clinical worsening of the veteran's opisthorchiasis. 8331 — the veteran has established the causal connection between the inability to obtain appropriate clinical management for opisthorchiasis and VEA service for the clinical worsening of opisthorchiasis. 8332 — the veteran has established the causal connection between the inability to obtain appropriate clinical management for opisthorchiasis and operational service for the clinical worsening of opisthorchiasis. or 8333 — the veteran has established the causal connection between the inability to obtain appropriate clinical management for opisthorchiasis and eligible service for the clinical worsening of opisthorchiasis. Clinical worsening and operational service [8332] or 8340 — the identified illness or injury which prevented the veteran from obtaining appropriate clinical management for opisthorchiasis is causally related to operational service. [14] [15] Clinical worsening and eligible service [8333] or 8341 — the identified illness or injury which prevented the veteran from obtaining appropriate clinical management for opisthorchiasis is causally related to eligible service.

Opisthorchiasis - Ingestion of fish from area endemic with Opisthorcis Felineus or Viverrini Factor
Last reviewed for CCPS 13 April 1995.
Preliminary questions [8304]
8311 — the veteran ingested raw, undercooked, pickled or smoked fish from an area in which the trematode Opisthorcis viverrini or Opisthorcis felineus was endemic, at some time.
8312 — the veteran ingested raw, undercooked, pickled or smoked fish from an area in which the trematode Opisthorcis viverrini or Opisthorcis felineus was endemic, prior to the clinical onset of opisthorchiasis. [Default true]
8306 — the veteran has established the causal connection between the ingesting of fish and VEA service for the clinical onset of opisthorchiasis.
8309 — the veteran has established the causal connection between the ingesting of fish and operational service for the clinical onset of opisthorchiasis.
or
8310 — the veteran has established the causal connection between the ingesting of fish and eligible service for the clinical onset of opisthorchiasis.
Clinical onset and operational service [8309]
8313 [22] the veteran ingested raw, undercooked, pickled or smoked fish from an area in which the trematode Opisthorcis viverrini or Opisthorcis felineus was endemic, prior to the clinical onset of opisthorchiasis, on operational service. the ingestion of raw, undercooked, pickled or smoked fish from an area in which the trematode Opisthorcis viverrini or Opisthorcis felineus was endemic, prior to the clinical onset of opisthorchiasis, on operational service, was due to the veteran's serious default, wilful act or serious breach of discipline. Clinical onset and eligible service [8310]
