Study of 44 people who died from #COVID19 in the first year of the pandemic showed researchers that disease-causing SARS-CoV-2 virus spread throughout the body – beyond just a respiratory disease – and remained in tissue for months.

SARS-CoV-2 infection and persistence in the human body and brain at autopsy - Nature

A study reports the distribution, replication and persistence of SARS-CoV-2 throughout the human body including in the brain at autopsy from acute infection to more than seven months following symptom onset.

Nature
Scientists found virus in cardiovascular, lymphoid, gastrointestinal, renal, endocrine, reproductive, muscle, brain and other tissue – but more extensive injury was seen in the respiratory tract. Thus, this study gives greater credence to early and effective treatment to prevent viral replication before it produces extrapulmonary symptoms.
