Investigation of the Detection Rate of Pathogenic Viruses in the Feces of Individuals With Non-gastrointestinal Infections

Investigation of the Detection Rate of Pathogenic Viruses in the Feces of Individuals With Non-gastrointestinal Infections

This project is a cross-sectional study. Investigators plan to search and collect 1600 publicly published fecal metagenomic and metatranscriptome data through the Pubmed database, by summarizing and analyzing them to construct an enterovirus database. 200 apparently healthy individuals are planned to be enrolled. At the time of enrollment, fecal specimens of participants will be collected, and their demographic characteristics, disease and medication history, gastrointestinal status, dietary habits, lifestyle habits, and mental health information will be recorded. Another 200 specimens will be collected from patients with parenteral virus infection. The demographic characteristics and pathogen test results of the parenteral virus infected patients will be reviewed and recorded. By virus metagenomic sequencing on fecal specimens, investigators will identify which viruses can be detected in the intestinal tract of apparently healthy people, and to explore whether parenteral infection viruses can be detected in feces.
