Cryptosporidiosis as parasitic disease

Cryptosporidiosis is known as protozoal infection caused by a parasite "Cryptosporidium parvum". Although this parasite is not new, it hasn't been recognized as a cause of human disease until 1976. The major protozoal infections symptoms include self-limiting diarrhea in the people with intact immune system. Permanent and life-threatening diarrhea can be experienced by people with weakened immune system, such as AIDS patients.

Cryptosporidiosis is a disease caused by the protozoan single-celled parasite Cryptosporidium. Nowadays, a lot of strength determining and reducing the risk of cryptosporidiosis from community and municipal water supplies.


One of the most common protozoal infections symptoms is diarrhea which is usually considered to be profuse and watery. It is often accompanied by abdominal cramping. Here are some other symptoms characterising the cryptosporidiosis: nausea, fever, headache, vomiting, loss of appetite. Rarely the Cryptosporidium parasite can cause pneumonia by infecting the lining of the respiratory tract or inflammation of the gall bladder. It's worth admitting that some people infected with Cryptosporidium may not become ill.


Who is thought to be susceptible to the cryptosporidiosis? Anyone. However, it may be more common in people with impaired immune systems as well as in children in special daycare centers. In healthy people with normal immune systems, symptoms and signs of the disease generally persist for two weeks or less. Be aware they may either improve or then worsen during that time period. At the same time, immune compromised people (those infected with HIV, people receiving cancer chemotherapy, people on steroid therapy, kidney dialysis patients, etc.) may not be able to clear the parasite and usually have much more severe and long-lasting cryptosporidiosis.


How can the doctor know whether the person is infected with cryptosporidiosis or not? According to medical practice, cryptosporidium is found in the digestive system. Any farm or wild animal, pet, bird, reptiles, and even fish can become infected. The infection is known to occur when the organism is ingested by a person. A few microscopic Cryptosporidium organisms may be required to infect a person.


Cryptosporidiosis is a disease which can be acquired by or animal-to-person or person-to-person transmission and by drinking contaminated water. A person-to-person way of transmission can occur through the direct contact or by food handling if the infected individual does not adequately wash his or her hands after the toilet. Infected people can shed the organism in stool for several weeks after they recover from the disease.


Cryptosporidiosis is transmitted by the faecal-oral route. That's why the group of individuals with the greatest potential to transmit the disease includes infected people with diarrhea, people incontinent of stool, people with poor personal hygiene as well as diapered children.


Speaking about  protozoal infections treatment results it's important to admit that there's no specific treatment for cryptosporidiosis. If the person suffers from dehydration fluid therapy can be helpful. The motility of the intestines can usually be reduced by anti-diarrheal drugs. They are known to provide some temporary improvement.


To prevent cryptosporidiosis acquiring and spreading, people are advised to wash hands after using a toilet and before handling food.
