Gnathostomiasis

 

Is a worm infection caused after eating raw fresh water fish contaminated with worm larval.

Usually in Thailand and Japan.After being eaten the larval migrate outside the intestine.

In the skin they cause itching but also can affect the lung (causing coughing), bladder (causing blood in urine) and brain (causing meningitis).

Blood tests help but sometimes-surgical removal of the worms helps identification. Treatment may require both medical and surgical.
