Veterinarians: The AVMA's Toxoplasmosis brochure can help you educate your clients.
Toxoplasma gondii oocysts must spend at least 24 hours (and up to 5 days, depending on environmental conditions) in the environment to become infectious to other animals, including people. They are more likely to survive in warm, humid environments. Oocysts are very resistant and can live for months or even years in the environment.
The content on this page is a condensed version of our brochure, Toxoplasmosis, available in English and Spanish.
