Parasites are creatures that invade a host, attach themselves externally and internally (to tissues and organs), and suck the nutrients from the host. Some parasites, such as certain worms, finally weaken and cause disease in the hosts.
Worms (nematodes) are long, naked, and boneless creatures that pass their young from eggs or cyst to larval (newly hatched worms) stage, maturing into worms in the tissues they infect, such as skin, muscle, lungs, or intestine (gut or digestive tract).
Based on the place of stay of the worms, the symptoms are produced
No symptoms or very few
Symptoms may occur immediately or take more than 20 years.
At times worms can be passed whole or in segments in the stool.
Digestive tract (stomach, intestine, liver, colon, and rectum) with intestinal worms causes abdominal pain, weakness, Diarrhea, loss of appetite, weight loss, vomiting, anemia, Malnutrition with deficiencies of vitamins (B 12) minerals (iron), fats, and protein. Itching around anus and vagina, inability to sleep, urinating in bed, and abdominal pain seen in pinworm infections.
Skin - Eruptions, Fluid-filled sacs called vesicles, Intense facial swelling, especially around the eyes.
Allergic reactions- Skin rash , Skin itchiness and itchiness around the anus
Lymphatic involvement - Swollen elephant-like legs or testicles
Tissue Nematodes or roundworms
Ascariasis (round worm) -- the eggs are found in the feces of the worm Ascaris and humans accidentally ingest them through contaminated soil/vegetbales. The worms can grow in the intestine and migrate through the blood to other sites, such as the lungs. They can grow up to 40cm. in length.
Tapeworms: These worms have many segments. They often invade the digestive tract, where they get their nutrition from their host.
Filariasis: A varied group of worms that invade the skin and lymphatic tissue.
