While the wife hadn’t tested positive, because of her exposure, she was also required to quarantine. The big concern was that a positive test after her initial quarantine period would trigger another 14-day quarantine. Fortunately, the property they were staying at was very helpful and offered...
For isolated cases after performing noise filtering operations, machine learning techniques achieved an accuracy between 98–100%. The results indicate that filtering noise from the dataset can improve the accuracy of COVID-19 case prediction algorithms. Keywords: healthcare data mining; COVID-19 ...
In extraversion depending on other-directed learning, the aim of this study is to investigate the conditions under which what is learned about COVID-19 is associated with positive COVID-19 coping by those expressing the personality trait of extraversion and how this compares with public opinion ...
The genetic make-up of an individual contributes to the susceptibility and response to viral infection. Although environmental, clinical and social factors have a role in the chance of exposure to SARS-CoV-2 and the severity of COVID-191,2, host genetics
Intervention exposure (vaccine uptake app) The intervention app will consist of 3 pathways: (1) step-wise decision support with narrative vignettes, (2) self-directed learning on each selected topic area, (3) geographic location-specific vaccine access information and corresponding push notifications....
Outcomes were ascertained 30d after the COVID-19-positive test until the end of follow-up. COVID-19 cohort (n = 154,068) and contemporary control cohort (n = 5,638,795). Adjusted HRs (dots) and 95% (error bars) CIs are presented, as are estimated excess ...
