Researchers from the Hubrecht Institute in Utrecht, Erasmus MC University Medical Center Rotterdam, and Maastricht University in the Netherlands have found that the coronavirus SARS-CoV-2, which causes COVID-19, can infect cells of the intestine and multiply there. Using state-of-the-art cell culture models of the human intestine, the researchers have successfully propagated the virus in vitro, and monitored the response of the cells to the virus, providing a new cell culture model for the study of COVID-19. These findings could explain the observation that approximately one third of COVID-19 patients experience gastrointestinal symptoms such as diarrhea, and the fact that the virus often can be detected in stool samples. The results of this study were published in the scientific journal Science on the 1st of May 2020.
Patients with COVID-19 show a variety of symptoms associated with respiratory organs – such as coughing, sneezing, shortness of breath, and fever – and the disease is transmitted via tiny droplets that are spread mainly through coughing and sneezing. One third of the patients however also have gastrointestinal symptoms, such as nausea and diarrhea. In addition, the virus can be detected in human stool long after the respiratory symptoms have been resolved. This suggests that the virus can also spread via so-called “fecal-oral transmission”.
