usmile1 also note that toxoplasma can cause the "blueberry muffin" rash (also rubella can as well) +

raddad So looking at the CDC website, it looks like "accidental ingestion of oocysts after touching cat feces" is the route you were talking about in the first paragraph, so inhalation of air droplets is wrong inherently. +1

Can anyone address the 3rd percentile head circumference? Does that qualify as microcephaly? Microcephaly plus Brazil had me sold on Zika, so I convinced myself that kissing could transmit it because I know it can transmit sexually.

I probably should have rethought it after not finding mosquito as a choice, and the classic Toxoplasmosis triad is there, but what's with the microcephaly?

UW ID: 15034 for those curious about Zika Classic findings are microcephaly, arthrogryposis (contractures), seizures, hypertonia, ocular abnormalities, cortical thinning, ventriculomegaly, and subcortical calcifications.

mamabara No answers as to why, but I also had the same line of thinking thanks to the Uworld question too... my best guess is that Toxo is the better answer based on the choices given? Even though the presentation (especially immigrating from Brazil) really made me think Zika +
