Symptoms of parasites may always be obvious. However, such symptoms may mimic anemia or a hormone deficiency. Some of the symptoms caused by several worm infestations can include itching affecting the anus or the vaginal area, abdominal pain, weight loss, increased appetite, bowel obstructions, diarrhea, and vomiting eventually leading to dehydration, sleeping problems, worms present in the vomit or stools, anemia, aching muscles or joints, general malaise, allergies, fatigue, and nervousness. Symptoms may also be confused with pneumonia or food poisoning. The effects caused by<unk> s range from mild discomfort to death. The nematode parasites Necator americanus and Ancylostoma duodenale cause human hookworm infection, which leads to anaemia, protein malnutrition and, in severely malnourished people, shortness of breath and weakness. This infection affects an estimated 440 million people. Ascaris lumbricoides and trichuris trichiura, which are two other soil-transmitted helminths (STH), affect approximately 480 million and 460 million people as well, with 70% of these three STHs occurring in Asia. Other prevalent areas including South America, Central America, Sub-Saharan Africa, Southeast Asia. Chronic hookworm in children leads to impaired physical and intellectual development, school performance and attendance are reduced. Pregnant women affected by a hookworm infection can also develop anemia, which results in negative outcomes both for the mother and the infant. Some of them are: low birth weight, impaired milk production, as well as increased risk of death for the mother and the baby.
