Thanks for posting your query. I understand your concern for your wife.
Positive serology for Toxoplasma IgG
and IgM does not mean that she is having an infection with the parasite.
Please get a avidity IgG test done to look for infection in the last 3 to 5 months. High avidity excludes Toxoplasma in the last 3 to 5 months.
is the drug of choice for Toxplasmosis. If the infection is confirmed, it is advisable to terminate the baby. Else, she can safely continue it.
Hope this helps.
