I don’t know very much about it, and I have no idea how long symptoms usually last, but I do know:

It is it’s very dangerous for pregnant women to get it, because they can pass it to the fetus.

Also, adults often have no symptoms, but can get severe symptoms. I think there is treatment for it if you think you have it. I don’t know if it is anti-parasitics or just symptom treatment.

If you think you have it I would go to the doctor, have it diagnosed, and ask the doctor what to expect. Many illnesses have similar symptoms.

From what I understand you need to have a compromised immune system for this to be serious. Maybe one of our jelly-docs will answer.

I dated a man who had it.

“Symptoms of an acute episode of toxoplasmosis, if any, are usually gone in about 7 days. Cysts remain in the body for life. The effects of congenital toxoplasmosis are also life-long.”

I don’t know but here’s my story. I have had cats for the longest time (in other words, almost always). When I was pregnant, the doctor told me “you probably already have toxoplasmosis, because most people with cats have already had it.”

I had a cat that had toxoplasmosis. It wasn’t pretty to see the effect on him. I got him vet treatment, which was working, but it was very tough on him and for me to see him.

The two websites I always check for these sorts of things:

http://www.cdc.gov/parasites/toxoplasmosis/gen_info/faqs.html

http://www.mayoclinic.org/diseases-conditions/toxoplasmosis/basics/symptoms/con-20025859

I clicked on the links and didn’t notice how they can tell if you have, or ever had, it. Do any of you know how it shows up? X-ray? Ultrasound? Blood test?

I think it is a blood test. They’ll look for antibodies. Hang on, I’ll check. http://www.nhs.uk/Conditions/Toxoplasmosis/Pages/Diagnosis.aspx

Yep.
