TL;DR Fecal matter from Vindolanda fort dated around 90 AD contains eggs of intestinal worms, and traces of antibodies to Giardia duodenalis.

Nothing of this is really news as not having parasitic worms is very recent development, and getting G. duodenalis with unsanitized water continues to be common today. Healthy immune system can deal with it, as it could in 90 AD, hence antibodies.

The story is an obvious attempt to produce as much words from as few facts as possible, and the headline is meaningless.
