My spreadsheet of studies showing the longer-term impact of #COVID19 has risen to 600 studies. New additions:
-COVID causes hypertension long term in non-hospitalized patients
MRI results indicate that changes in brain function contribute to cognitive complaints in people with long COVID even after 2 years
Some COVID-19-recovered patients have persistent colonization of SARS-CoV-2 in their cardiac tissue
SARS-CoV-2 breakthrough infection leads to disturbances in cellular immunity. (1/2)
