Toxocariasis: All You Need To Know

Toxocariasis is a disease caused by a type of roundworm, usually found in cats and dogs. The worms are spread when cats or dogs, which have caught the larvae of the parasite, pass the larvae to humans through their feces. If these larvae are ingested by humans, they can cause acute and sometimes severe health problems. In this article, we will discuss the symptoms, diagnosis, and treatment of Toxocariasis.

Symptoms of Toxocariasis

The most common symptom of Toxocariasis is an itchy, red rash that may appear anywhere on the body. Other symptoms can include fever, fatigue, joint pain, and a cough. In severe cases, symptoms such as cough, fever, and headaches can also occur. If Toxocariasis is left untreated, it can lead to more serious complications like eye and liver damage.

Diagnosis of Toxocariasis

Diagnosing Toxocariasis is difficult as the symptoms can resemble those of other illnesses. Your doctor may take blood and other tests to help diagnose the condition. Blood tests may show if you have an infection and may also include a test for antibodies against the parasites. Imaging tests such as X-rays and CT scans may also be used to look for the parasites in your body.

Treatment of Toxocariasis

There are several treatments available for Toxocariasis, depending on the severity of the infection. The most common treatment is antiparasitic medications, which are taken orally or by injection. Surgery may also be necessary in some cases, to remove the parasite from the body. Other treatments may include medications to reduce inflammation and relieve symptoms, as well as lifestyle changes to help reduce the risk of reinfection.

Preventing Toxocariasis

The best way to protect yourself from getting Toxocariasis is to keep cats and dogs away from areas where they may defecate. Washing your hands after handling a pet is very important. Also make sure that your cats and dogs are regularly wormed. Other preventative measures include avoiding drinking water from areas where animal waste is likely to be present.
