Toxocariasis

This particular disease emanates from a parasite found in domesticated animals (cats and dogs most- commonly) that creates an infection somewhere in the host.  However, this damaging parasite can also be located in the excrement of hosts and remain in an inactive state for quite a while.  In fact, even though the parasites can remain dormant, the disease itself is still very dangerous to contract and is one of the main contributors to causing blindness.

It is a disease that is not new to human beings as it was first discovered during the 18th century.  It was first categorized under the contemporary nomenclature toward the middle of the 20th century.

Causes

Typically, humans will become afflicted with this disease after ingesting the parasites that cause the disease by inadvertently consuming dirt with the parasite present or indirectly through parasites that might be stored in or on other parts of the body.  The parasites are very adept at spreading and nesting in various parts of the body.

Optimal conditions for the growth and spread of the parasites that cause this particular disease involve a humid and balmy atmosphere that is not associated with the initial host.  Domesticated animals that carry this particular parasite will transmit it to offspring and produce a continuous cycle of hosts if uninterrupted or treated.

Signs

The amount of impact felt that would indicate a person is afflicted with this disease would likely be proportionate to the volume of parasites present in the body.  However, it should be emphasized that even a small number of parasites can cause crippling damage to body, if left untreated, such as the aforementioned loss of sight.  As such, the largest focus concerning treatment is to prevent the parasites from causing damage to the degree that eyesight is jeopardized.

However, it is important to note that this disease can be tricky to diagnose as many of the signs and symptoms are similar to a variety of other infectious diseases that exist.  Thus, if you suspect an infection it is crucial to seek the advice of a medical professional as soon as possible.

Cures

In humans, a resolution will come naturally to this ailment after a prescribed period of time.  Since a human host cannot provide the optimal conditions to grow the parasitic population internally, there is usually not an unlimited life cycle for this disease in humans.  Treatment for humans often involves the use of several types of steroids to fight the infection and help the immune system regain dominion over the processes of homeostasis.  Modern developments in surgical techniques mean that some patients can have the parasites laser-removed from their body as well.
