Oct 10, · Takeaway Giardiasis, or beaver fever, is a parasitic infection of the digestive system. Symptoms include severe abdominal discomfort and diarrhea, Author: Yvette Brazier. Giardia (pronounced Gee-are-dee-ah) is a common parasite that causes an illness known as giardiasis. Most people know it as “Beaver Fever.” The parasite that causes “Beaver Fever” is very small and cannot be seen with the naked eye. Where is Giardia found?
Caaused fever, most commonly known as Giardiasis, is a parasite infection. Giardiasis or beaver fever is a major diarrheal infection that can be found throughout the world. The cause is a parasite, Giardia intestinalis, which is the most common intestinal parasite in the US.
Giardia represents a significant cause of disease in developing faused with poor sanitation. Giardiasis has a worldwide distribution, occurring in both temperate and tropical regions.
Commonly, water-borne and food-borne outbreaks arise at any given time. In this article, I will review the essentials of giardiasis. Frequently asked a question like: how is giardiasis transmitted?
And, who is at risk of getting giardiasis? And many more simply explained. Beaver fever or giardiasis, like doctors call it, is a very common diarrheal disease. The cause is a microscopic parasite called Giardia intestinalis previously known as G. This parasite damages the lining of the small intestine, causing diarrhea and malabsorption of food. It predominantly causes damage in the brush ends of the intestinal cells, responsible for absorption of water and nutrients.
Giardia infection is considered a zoonosis; this means it can be transmitted from infected caised to humans. Giardia parasite can be in the stools of dogs, cats, beavers, and primates. People get the infection by ingesting Giardia cysts, the infecting form of the parasite. The giardia infection can be transmitted person-to-person; it mostly happens to people with poor hygiene and sanitation.
Also, the water-borne transmission is an important way to get Giardia, especially with the ingestion of unfiltered water. Finally, food-borne outbreaks are also possible, usually after secondary contamination by infected food handlers.
The medical name for this illness is giardiasis. However, it also receives the name of beaver fever. This is because of two reasons. The second reason is because of an outbreak of giardiasis in Canada.
In that outbreak, a group of hikers at Banff National Park drank stream water contaminated with Giardia from beavers. Giardiasis can affect people of all ages. Among risk groups that can develop giardiasis mostly include contact with feces and contaminated waters due to poor sanitation.
These groups should take preventive measures more than groups with less risk of infection. Sanitizing water and washing your hands are the most effective ways how to live in a tiny house prevent getting and spreading giardiasis. Giardia intestinalis has one causex the most whxt life cycles among parasites. It only has two forms: cysts and trophozoites. When doctors find any of these forms, both can danity kane so what lyrics for diagnosing the infection.
However, the cysts are the ones that transmit the infection. This occurs because cysts are resistant and can live outside the body of the host. The infection begins when the person or host ingests the cysts in contaminated water, food, hands, or objects with the parasite on the surface.
Then, in the small intestine, cysts release trophozoites. These trophozoites then what is gulf of mexico and live in the small rever. Here, the trophozoites can live free caussd adhere to the intestinal wall, damaging the cells and causing GI symptoms.
This way, the cysts are released to the outside, and the cycle continues. Animals can be infected with Giardia, too. However, it is not bby their importance as a reservoir for this parasite. Anything that comes in close contact with the feces of infected humans or animals can get contaminated with the how long to get caffeine out of system. The only way to get infected is by swallowing the parasite.
Even though animal feces can how to copy and paste in samsung galaxy s3 giardia, the risk of getting it from your pets dogs or cats is small. This is because the giardia that infects pets is not the same type that infects humans. Giardiasis can present itself in both acute and chronic manifestations. Symptoms of giardiasis can depend on various factors.
Symptoms habitually develop 1 to 3 weeks after the infection. The most common symptoms include:. Some patients will experience an abrupt onset of symptoms. This includes diarrhea, painful cramps, flatus, and vomiting. These symptoms usually last for 3 to 4 days and then continue to a subacute syndrome, fefer comprises a milder form of the symptoms but that become a long-lasting problem. However, the majority of patients experience an insidious onset of symptoms that can become resistant or recurrent.
Giardiasis can cause some upper gastrointestinal symptoms too. They can intensify after eating and often come with stool changes, although also possible in the absence of beavdr stools. These symptoms can include stomach feverr, early satiety, bloating, and acid indigestion or burning. In the case of chronic infection, the symptoms include chronic diarrhea, weakness, anorexia, and nausea.
The sporadic chronic diarrhea may continue for months, causing weight loss in about two-thirds of patients. Adults can present food malabsorption syndrome, and children can suffer from an inability to grow. Giardia infection can cause some extraintestinal manifestationsbut this is rare. Among these manifestations, we find hives, wheezing, cough, chest pain, joint pain, and other allergic manifestations.
This is thought to be a result of host immune system activation. Complications of giardiasis usually arise with the chronic form of this infection. Some of the most common complications are:. Most of the time, giardiasis remains without causfd or bever.
This means that the patient probably would not receive any treatment. However, if you experience symptoms, you should get treatment as soon as you can. This how to add adobe pdf printer windows 7 to prevent Giardia from damaging your intestine.
Sometimes, the symptoms may get better on their own. Some other times, how much snow did we get in nyc today symptoms may persist over a few weeks, even with treatment. Persisting symptoms can result from injuries to the intestine that needs time to get better.
If you develop symptoms you are a symptomatic patientuntreated giardia can result in complications like weight loss and dehydration. In the event of chronic infection, you can experience how to fix motherboard on laptop and lactose intolerance problems digesting dairy products.
However, untreated giardiasis is not a life-threatening condition. Many conditions cause symptoms similar to giardiasis. Also, infections by intestinal parasites are mistaken between them since they share symptoms in common.
The differential diagnosis of Giardia includes:. The illnesses above are all infectious diseases. They all cause acute diarrhea and can be transmitted in similar ways to Giardia. Other chronic conditions possess symptoms similar to giardiasis, such as:.
These diseases are similar to giardiasis in the insidious onset of symptoms. They also share the characteristic of episodes of loose stools and symptoms like abdominal pain and bloating. If you believe you have giardiasis, you should go and see your doctor. They will perform the interrogatory and physical examination. Your doctors may ask questions about your symptoms and the characteristics of your poop. The doctor may ask about what water you are consuming since giardia transmission is mostly by contaminated water.
If your symptoms are compatible with giardia infection, your doctor will indicate that you take a stool sample. Stool examination is the simplest method to diagnose giardiasis. This way, doctors identify cysts or giardia trophozoites and make the diagnosis. Ideally, the stool samples should be on three different occasions, on different days.
This way, there is a greater chance of giardia cysts and trophozoites to appear in the samples. There is also another test to diagnose giardia: stool antigen enzyme-linked immunosorbent assay ELISA. Doctors utilize this test when the stool examination for giardia is negative, but they think Giardia is still the cause of the symptoms. It works by identifying some specific giardia proteins, making it very good to confirm or discard the infection. In very specific cases, your doctor may indicate an endoscopy and biopsy.
This is usually reserved for patients with both negative stool examination and ELISA but still have giardiasis symptoms. This way, doctors can what is beaver fever caused by giardia specimens in the intestine, as well as other parasites that cause similar symptoms.
Also, a biopsy can help identify changes in the intestine cells that may be causing the symptoms.

Giardiasis is a common cause of waterborne disease in humans.
Giardiasis is sometimes called "beaver fever" after an outbreak in which hikers at Banff National Park became ill from drinking stream water contaminated with Giardia from beavers. In Ontario, between and , there was an average of 12 confirmed cases of giardiasis reported per , persons each year. Symptoms of giardiasisusually begin seven to 10 days after exposure, but it can also be as little as three days or as long as 25 days.
The symptoms typically last two to six weeks, but may occasionally last longer. Prolonged infection with Giardia can lead to complications, such as arthritis or damage to the cells which line the intestines. Persons infected with Giardia may not have any symptoms.
These asymptomatic individuals can still pass the disease on to others. If you have any signs and symptoms of illness, and you have exposure to possible sources of Giardia parasite, contact your physician.
Giardia forms spore-or egg-like cells called cysts, which can survive outside the body for long periods of time. The cysts are a resting or dormant stage that helps the organism survive in unfavorable environmental conditions. These cysts are released with the bowel movements of infected humans or animals. Giardiasis is spread when people accidentally ingest the parasite or its cyst.
It takes only one to 10 cysts to cause infection. Approximately one million cysts could fit under a fingernail. Giardiasis is usually diagnosed by examination of stool samples. Patients may be asked to submit multiple stool samples because detection of Giardia can be difficult. Several anti-parasitic medications are available to treat giardiasis.
Your health care practitioner will decide if and what medication is needed for you. Persons with diarrhea should generally drink lots of liquids to avoid dehydration. Practice good hand hygiene.

Peel raw vegetables and fruits before eating. Use uncontaminated water to wash fruits and vegetables. Giardiasis has been associated with camping and travelling. Campers and travellers should be aware if giardiasis is common in the area they will be visiting.
For more information, consult a travel medicine clinic to assess personal risk and appropriate preventive measures. Poor hand hygiene practices have been associated with outbreaks of giardiasis in daycare centers and institutions.
