Here's how it happens:
* Dogs get infected: Puppies are often infected with roundworm larvae through their mother's milk or by ingesting infected soil.
* Larvae migrate: The larvae migrate through the dog's body and can end up in their feces.
* Humans become infected: Humans can become infected by accidentally ingesting roundworm eggs from contaminated soil or by coming into contact with infected dog feces and then touching their mouth.
Symptoms in humans:
* Visceral larva migrans (VLM): This is the most common human infection. The larvae migrate through the body, often to the liver, lungs, or eyes, causing fever, cough, fatigue, and sometimes serious complications.
* Ocular larva migrans (OLM): This occurs when the larvae migrate to the eye, causing vision problems and potential blindness.
How to prevent infection:
* Regular deworming of dogs: Veterinarians recommend regular deworming for puppies and adult dogs, especially for those who go outside.
* Good hygiene: Wash hands thoroughly after handling dog feces, playing with dogs, or gardening.
* Avoid contact with infected soil: Children should be supervised when playing in areas where dogs might defecate.
* Wash fruits and vegetables thoroughly: This helps prevent the ingestion of roundworm eggs that may be present in the soil.
If you are concerned about the possibility of roundworm infection, it's essential to see a doctor for diagnosis and treatment. Remember, it's always best to consult with a veterinarian for guidance on dog health and parasite prevention.
