Some parasites, such as mosquitoes, fleas, ticks and tsetse flies, attack the external part of the body, while others, such as tapeworms, attack the internal parts of the body. Both sets of parasites can cause adverse effects.

Parasitic infections may cause mood and anxiety issues, including nervousness, depression, unclear thinking, slow reflexes and restlessness. Sleep disorders may include grinding of the teeth during sleep, insomnia, drooling while asleep and bed wetting.

Skin disorders brought about by parasitic infections may include hair loss, dry skin, hives, itchy anus, papular lesions, swelling and sores. Fatigue symptoms include lethargy and a lack of motivation to work. Other symptoms include nausea, bloating, bloody stools and abdominal pain.
