Roundworms are a type of parasite that can infect and reside within the human body. The most common type of roundworm infection in humans is called ascariasis, which affects up to one billion people throughout the world, according to medical experts at the University of Maryland Medical Center. The symptoms of a human roundworm infection can vary based upon the type of parasite responsible for the infection. People who develop roundworm infection symptoms should seek treatment from a medical provider as soon as possible.
Stomach Upset
Patients infected with only a few roundworms may not experience any noticeable symptoms. Large numbers of roundworms within the intestines can cause stomach upset symptoms in affected patients, explain medical professionals at the Cleveland Clinic. These stomach upset symptoms can include abdominal pain, nausea or vomiting. Certain patients can also experience diarrhea or may observe blood within their stools, reports the UMMC. Affected patients may notice the presence of a worm within their vomit or stools. These stomach upset symptoms can be uncomfortable and may contribute to loss of appetite in affected patients.
Flulike Symptoms
Flu-like symptoms can emerge as roundworm infection symptoms in humans. These symptoms can include fatigue or fever, report medical experts with Patient UK, a comprehensive health information website supported by general practitioners in the United Kingdom. Fevers can be high and may occur in conjunction with headache, chills or sweating. Patients who develop persistent flu-like symptoms should consult a doctor for further evaluation and care.
Skin Rash
Roundworms that infect the skin can cause skin rash symptoms in affected patients, warn medical professionals at the UMMC. The affected skin can appear red, swollen and irritated and may begin to itch. Certain patients may also develop blisters across affected skin, which can burst and ooze fluid. These skin lesions can be painful or uncomfortable and may require antiparasitic medication to resolve symptoms.
Breathing Difficulties
If roundworms infect a human's lungs, the affected patient can experience breathing difficulties as a symptom of infection, report health officials with the Centers for Disease Control and Prevention. Patients can begin to wheeze or cough and can experience sensations of pain within the chest due to roundworm infection. These symptoms can be serious and affected patients should contact a doctor for further treatment and care.
