On May 18, 2022, SARS-CoV-2, or at least pieces of it, sticks around longer in some infected individuals than respiratory sample testing would suggest, a study found.

After respiratory samples tested negative, a small proportion of the 113 study participants continued to shed SARS-CoV-2 RNA in their fecesﾗabout 4% of them for at least 7 monthsﾗand those people were more likely to report ongoing gastrointestinal symptoms, researchers reported in the journal Med.
