Studies on re-admission of diseases other than COVID, such as influenza, concluded that they were caused by complex interactions within the immune system.
Patients are currently considered cleared of COVID after two sequential negative tests.
Researchers from the bio-information firm “nference” performed a retrospective analysis of 266 patients treated for COVID.
This analysis compared patients admitted or re-admitted after viral clearance with patients hospitalised before viral clearance but did not require hospitalisation after viral clearance.
The researchers at nference used neural network models to draw out factors such as comorbidities in their dataset. The results showed that the hospitalised post-viral clearance group showed acute kidney injury (n=15 (16.1%)), anaemia (n=20 (21.5%)), and cardiac arrhythmia (n=21 (22.6%)) in the year preceding the onset of COVID.
The authors of the study by nference hope the information will guide further research into risk factors for COVID.
