Major groups of parasites include protozoans (organisms having only one cell) and parasitic worms (helminths). Of these, protozoans, including cryptosporidium, microsporidia, and isospora, are most common in HIV-infected persons. Each of these parasites can infect the digestive tract, and sometimes two or more can cause infection at the same time.
In humans, accidental infection can occur through the consumption of contaminated water or food. The symptoms of Eurytrematosis in ruminants include weight loss, diarrhea and anemia. Infected animals may also exhibit signs of liver damage such as jaundice and ascites. In humans, symptoms can include abdominal pain, diarrhea and weight loss.

3 Unusual Signs of Dehydration. Craving something sweet and/or salty can signal that your body needs more fluids. Fevers and chills: especially dangerous if the fever is over 101 F.
A determination of whether or not the person has dehydration is an important part of the assessment, with dehydration typically divided into mild (3–5%), moderate (6–9%), and severe (≥10%) cases. [1] In children, the most accurate signs of moderate or severe dehydration are a prolonged capillary refill, poor skin turgor, and abnormal ...
The term "dehydration" has sometimes been used incorrectly as a proxy for the separate, related condition of hypovolemia, which specifically refers to a decrease in volume of blood plasma. [3] The two are regulated through independent mechanisms in humans; [3] the distinction is important in guiding treatment. [25]
Signs and symptoms of hookworm infection vary by host and hookworm species. In humans, the first sign of infection is itching and skin rash. Humans with light infections may show no symptoms, but humans with heavy infections may have abdominal pain, diarrhea, loss of appetite, weight loss, fatigue and anemia.
G. duodenalis is the most widespread intestinal parasite affecting humans. The parasite Giardia duodenalis can be found all over the world, in both developing and industrialized nations. However, human infections are most common in tropical and subtropical climates.
