Do We All Have Toxoplasmosis?

A reader named Bo Svensson sent me a note about toxoplasmosis. I have heard of it in cats, but humans? Apparently quite a few people have this parasite. Does it affect our behavior?

So I asked for metastudies, and I got them …

1. "The One Health Approach to Toxoplasmosis: Epidemiology, Control, and Prevention Strategies" (paper and a really good article)

2. "Beyond the association. Toxoplasma gondii in schizophrenia, bipolar disorder, and addiction: systematic review and meta-analysis" (paper)

3. "Toxoplasmosis – A Global Threat. Correlation of Latent Toxoplasmosis with Specific Disease Burden in a Set of 88 Countries" (paper)

4. "Driving us mad: the association of Toxoplasma gondii with suicide attempts and traffic accidents - a systematic review and meta-analysis".(paper)

Is this significant? Could Donald Trump be a carrier? What do you think?
