With the large-scale epidemic of the new coronavirus, new virus mutants are constantly appearing.
In the two years since the epidemic, we have realized that the new crown is not just a respiratory disease, but affects multiple tissues and organs of the human body
On April 12, 2022, researchers from Stanford University in the United States published a research paper entitled " Gastrointestinal symptoms and fecal shedding of SARS-CoV-2 RNA suggest prolonged gastrointestinal infection " in the Cell sub-journal " Med " .

The study showed that even if the virus was no longer detectable in the respiratory tract, 12.
In the study, the researchers used an early clinical trial launched at Stanford University in May 2020 to test a possible treatment for mild COVID infections
Many other studies have focused on viral shedding in severe COVID patients, however, this study is the first to assess the presence of viral RNA in stool samples collected from mild to moderate COVID patients
The study found that after the first week after diagnosis, 49% of patients had SARS-CoV-2 RNA residues in their stool
Four months after diagnosis, when their lungs no longer had SARS-CoV-2, 12.
Seven months after the initial diagnosis, viral RNA was still present in the stool of 3.
The researchers noted that RNA constitutes the genetic remnant of the coronavirus, not the actual live virus, so human feces are unlikely to be infectious
The lingering COVID virus in the gut does suggest a potential impact on long-term disease, the researchers said
In addition, the researchers suggest that SARS-CoV-2 may stay in the gut and even other tissues longer than it does in the respiratory tract, where it basically continues to stimulate our immune system and induce some long-term consequences
Long-term COVID has become such an established problem that many major medical centers have established their own long-term COVID clinics to try to figure out symptoms and potential treatments, said the medical director of the National Foundation for Infectious Diseases
The authors say these data add to the idea that cells in the gut may themselves be involved in COVID-19 infection, and that they may be contributing factors to certain symptoms, such as abdominal pain, nausea, and vomiting, which may be one aspect of long-term COVID symptoms
