Toxocariasis, Visceral Larva Migrans Syndrome

Toxocariasis and Visceral Larva Migrans syndrome are serious diseases caused by infestation of the larval roundworms Tohosaga canis and T. cati, which are parasites of dogs and cats, respectively. Although these worms do not usually develop in humans, they can be acquired by ingesting worm eggs, which may be found on contaminated surfaces, food, and drinking water if they contain feces from infected pets.

After entering the human body, the larvae begin to migrate through tissues, causing destruction and inflammation. This can lead to an enlarged liver and the development of pneumonia (pneumonia), accompanied by fever, joint and muscle pain, vomiting, seizures and an itchy rash. In some cases, the larvae can temporarily settle in the retina of the eye, causing inflammation and the development of granuloma.

Toxocariasis and visceral wandering larva syndrome are common throughout the world, with children being most susceptible. This is because children often play on contaminated surfaces and may accidentally ingest worm eggs.

The diagnosis of toxocariasis and visceral "wandering larva" syndrome is established on the basis of clinical manifestations and laboratory results. Severe cases are treated with thiabendazole, which helps kill the roundworm larvae.

To prevent toxocariasis and visceral wandering larva syndrome, it is recommended to regularly treat pets for parasites, keep hands and food clean, and avoid contact with contaminated surfaces, especially for children.

Toxocariasis and visceral wandering larva syndrome are serious diseases that can lead to serious complications. Following good personal hygiene and regularly checking your pets will help prevent the development of these diseases.

Toxocariasis or toxocarosis (Greek τόξος - “onion” and κάρῡος - “thief, robber”) is a parasite that causes decay of internal organs and tissues. In 90% of cases it is transmitted by domestic animals: cats and dogs.

Toxocaras become infected due to violation of hygiene rules. Parasite eggs enter the mouth even through food. High concentrations of larvae are dangerous for small children. Adults often experience mild or absent symptoms, which makes timely detection and treatment of the disease difficult.

Symptoms of toxocaiosis are expressed in inflammation of the lungs, heart and blood vessels. The disease affects the lungs, liver, gallbladder, brain, eyes, and joints. It is also characterized by intestinal disorders, numbness of skin areas and symptoms that are complained of during pneumonia: temperature up to 38°C, cough, increased sweating.
