Latest COVID-19 Publications

Some key recent publications to be aware of:

This paper summarises the clinical and radiologic characteristics of 27 confirmed cases of COVID-19 and analyses the association of radiological findings with mortality cases.

This article found that the mean viral load of severe COVID-19 cases was around 60 times higher than that of mild cases, suggesting that higher viral loads might be associated with severe clinical outcomes. Mild cases were found to have an early viral clearance, with 90% of these patients repeatedly testing negative on RT-PCR by day 10 post-onset. By contrast, all severe cases still tested positive at or beyond day 10 post-onset. The data suggests that, similar to SARS in 2002–03, patients with severe COVID-19 tend to have a high viral load and a long virus-shedding period, hence the viral load of SARS-CoV-2 might be a useful marker for assessing disease severity and prognosis.

This prospective longitudinal study systematically describes the temporal changes of CT findings in COVID-19 pneumonia and summarises the CT findings at the time of hospital discharge. The extent of lung abnormalities on CT peaked during illness days 6-11. The temporal changes of the diverse CT manifestations followed a specific pattern, which might indicate the progression and recovery of the illness.
