Intestinal Parasites STI/STD Brief
These briefs are intended to give readers (specifically those who weren’t aware many of these STIs/STDs existed) an overview of each STI/STD, their commonality, treatment options, and diagnostic tests available.
This information is by no means all-encompassing and The STI Project encourages using these briefs as primers and then further delving into the resources section when subsequent questions arise.
STI Masterclass: Breaking Through the Fear, Shame, and Stigma of an STI Diagnosis
If you’re fed up with feeling unworthy, less-than, damaged, or limited by your STI, then join the next cohort in the 60-Day Masterclass, and leave feeling empowered, knowledgable, and confident again!
