According to Tim Spector, a professor of genetic epidemiology at King's College London, the new coronavirus pneumonia (COVID-19) variant virus strain Omicron (Omicron) may stay in the intestine, causing patients to develop 6 related symptoms including nausea, diarrhea, vomiting, abdominal pain, heartburn and bloating.
Spector also leads the "Zoe New Coronary Pneumonia Symptom Study", which developed the "ZOE COVID Symptom Study" application (App), which collects and counts patients' symptoms.
ZOE lists diarrhea as a general symptom of Covid-19, but describes it as a "little-known" symptom.
"The diarrhoea caused by Covid-19 is similar to the upset stomach you might experience with common gastrointestinal diseases such as rotavirus or norovirus," the website explains. It adds: "We believe Covid-19 causes diarrhoea, Because viruses can invade intestinal cells and disrupt their normal function.”
ZOE says it's a rare Covid-19 symptom that still affects those who are infected.
It states: "Coronavirus-related abdominal pain is full-scale pain in the middle of the abdomen. You may experience pain around the abdomen."
Patients are most likely to develop the symptoms in the first few days of illness, ZOE said.
This could mean that a patient may not even test positive until they have abdominal pain.

Spector said the Omicron virus could end up in a patient's gut, which means that when people are infected with Omicron and have the six bowel symptoms, they may test negative, because they don't test in the nose or mouth. out Omicron.
"We know that this virus tries to get into the mouth or nose, it's in the respiratory system or the lungs, and it sometimes gets into the gut," he explained.
He said that long-term traces of the virus have been found in the intestines of "Long Covid" patients.
"We know that the virus travels to different parts of the body, and Omicron or other mutated strains may attack the gut," he said.
He said that using only nasopharyngeal swabs to test whether people are diagnosed may miss many cases.

ZOE released the latest list of the 20 most common symptoms in the UK. In addition to nasal discharge, headache, fatigue, sneezing and throat being the five most common symptoms, "lower back pain" and "night sweats" are the latest to enter the list.
