The main reason that doctors forget about paragonimiasis is the lack of accurate diagnostic methods
The eggs of these worms are secreted with phlegm, and can be swallowed with saliva. This means that eggs of paragonimus can be found in sputum or feces tests. But, unfortunately, these parasites are hardly remembered and there are practically no specialists who know how their eggs look. The accuracy of this analysis is the same as the analysis of feces for worm eggs.
At present, only on the Imedis, with a good specialist, it is possible to accurately diagnose and destroy paragonimus.
