Chinese medical experts say they have not yet had a patient who was infected by fecal-oral transmission. In other words, they have had no cases of people coming in that contracted the virus via contact with contaminated fecal matter. The statement comes after doctors found viral nucleic acid, a DNA component of the virus, in tests of patients' stool and rectal swabs. Researchers say the findings indicate that the novel coronavirus can be spread through contact with contaminated fecal matter and not just from contact and droplets from an infected person.
