Infection people happens during the swallowing invasive larvae to the contaminated food and water. During the parasitizing of singamus at people the tracheobronchitis which is followed by fits of coughing with a phlegm, sometimes a pneumorrhagia, an asthmatic syndrome is observed.
Diagnosis put at detection of eggs of singamus in a phlegm, excrements, sometimes adult singamusa are thrown out with a phlegm at cough or find them at a bronkhoskopiya.
