Sponsored by ProgenaBiome · Observational
This study seeks to determine whether the virus which causes COVID-19, SARS-CoV-2, is shed in the stools of patients who are infected.
In this study the stool of patients who are being treated for COVID-19 will be tested during treatment and then again following treatment to determine if the virus is shed in the stool during infection, afterwards, or both.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Correlation of Microbiome to Disease via Relative Abundance Found in Microbiome Sequencing
Relative abundance of bacterial classes within taxonomic phyla and, more broadly, within their domain will be analyzed by sequencing the gut microbiome. These data will then be categorized among specific gastrointestinal disease types.
Time frame: One year
