Total UK COVID-19 Cases

As of 2nd April

NB: Public Health England has now moved to a different reporting time for UK COVID-19 fatalities, as family consent is now needed to release mortality statistics. Hence the reported figures may not actually be the deaths that have taken place over the past 24 hours, meaning caution needs to be exercised when comparing figures from one day to the next.

Latest COVID-19 Publications

Some key recent publications to be aware of:

Identifcation of a potential mechanism of acute kidney injury during the COVID-19 outbreak: a study based on single-cell transcriptome analysis

Published 31st March 2020

Acute kidney injury (AKI) is one of the important complications of COVID19, occurring in 0.5–7% of cases and in 2.9–23% of ICU patients. However, whether the AKI of COVID-19 is caused by a coronavirus-induced cytopathic effect or cytokine storm-induced systemic inflammatory response remains unclear.

This study aimed to deduce the underlying mechanism of AKI in COVID-19, by performing single-cell RNA sequencing analysis to identify candidate kidney host cells. They concluded that the cytopathic effects of SARS-CoV-2 on podocytes and proximal straight tubule cells may cause AKI in patients with COVID-19.

The ACE2 expression in human heart indicates new potential mechanism of heart injury among patients infected with SARS-CoV-2

Published 30th March 2020

Angiotensin-converting enzyme 2 (ACE2), the key host cellular receptor of SARS-CoV-2, has been identified in multiple organs, but its cellular distribution in human heart is not illuminated clearly. This study investigated ACE2 expression in adult human hearts from healthy and diseased individuals, to illuminate the potential capacity of heart infection by SARS-CoV-2.

The study revealed that pericytes with high expression of ACE2 might act as the target cardiac cell of SARS-CoV-2, and that patients with heart failure showed increased ACE2 expression at both mRNA and protein levels, meaning that if infected by the virus these patients may have higher risk of critical illness. The findings of this study may explain the high rate of severe cases among COVID-19 patients with cardiovascular disease.
