They additionally discovered virus able to infecting cells in stool taken from a affected person with Covid-19.
“A 68-year-old female patient presented with fever, sore throat and productive cough and developed diarrhea after admission to Princess Margaret Hospital,” Zhou and colleagues wrote. “We isolated infectious virus from her stool specimen,” they added.
“Here we demonstrate active replication of SARS-CoV-2 in human intestinal organoids and isolation of infectious virus from the stool specimen of a patient with diarrheal COVID-19.”
Separately, a crew at University Medical Center Hamburg-Eppendorf in Germany carried out autopsies on 27 sufferers who died from Covid-19. They discovered the virus in quite a lot of organs.
The virus appeared to do particularly nicely within the kidneys, they wrote — one thing which may clarify the excessive fee of kidney harm seen amongst Covid-19 sufferers.
The capability of the virus to assault varied organs would possibly irritate pre-existing circumstances, they added. People with coronary heart illness, diabetes and kidney illness are particularly susceptible to the brand new coronavirus.
