Recognizing the Indicators of Human Body Worms

8. Acute Coughing and Lung Congestion

Some worms can trigger lung symptoms, including shortness of breath, coughing, and congestion. Eating undercooked crab contaminated with flatworms can lead to paragonimiasis, a worm infection of the lungs. The infection starts in the intestinal tract, but the worms can move to the lungs where they cause cough, shortness of breath, and chest discomfort. Paragonimiasis is not common in the United States, although it still occurs in other countries. Most of the parasites that cause lung symptoms are found in tropical and sub-tropical climates.
