We compute the expected and observed numbers of cases for each cylinder and perform a maximum likelihood test with null hypothesis H0:“There is no difference in risk of COVID-19 between the inside and outside of the cylinder”, and alternative hypothesis HA:“There is a higher risk of CO...
A test that can be run outside laboratory settings is called a point-of-care test. Ideally, it would be a relatively inexpensive test that can be run with many samples and return results in up to 30 min with naked-eye detection. This also becomes important if the zoonotic origin of ...
Test reliability, standard errors, and information function of the DASS-21 subscales (depression, anxiety, and stress subscales are indicated with yellow, blue, and red lines, respectively). Full size image On the depression sub-scale, item information was maximized for Item 21 (“life is mean...
We excluded individuals with one or more positive tests in the period 31 to 180 days after the first positive test. In this way, we could exclude new onset symptoms that were due to a new SARS-CoV-2 infection and not related to the first SARS-CoV-2 infection (i.e., all positive tes...
5a with respect to p and \(\omega \). The resulting curve divides the parameter space into two regions: one for stable disease-free equilibria (yellow) and one corresponding to stable endemic equilibria (blue). b System responses obtained at the test points P1 (\(p=0.44\), \(\omega =...
Collecting our evidence from the largest misinformation dataset used in the COVID-19 misinformation literature with close to 11,000 pieces of falsehood, we explore patterns of misinformation production by employing a variety of methodological tools including algorithms for text similarity, clustering, ...
and contacts of confirmed cases traced over the previous two weeks [130]. In individuals with a high suspicion rate, the test was repeated after 48 h [130]. The airport testing included body temperature and clinical assessment and the use of a rapid diagnostic test for severe-acute-respiratory...

Controlling COVID-19 via test-trace-quarantine Article Open access 20 May 2021 Introduction On March 11, 2020, the World Health Organization declared COVID-19 a pandemic and called for coordinated mechanisms to support preparedness and response efforts across health sectors1,2,3,4. Predictive mod...
We found that an olfactory self-test using household odorants performs well at detecting COVID-19, and that it continues to perform more modestly but still significantly in participants with symptoms but without COVID-19, or most critically, with COVID-19 but without symptoms. In this respect...
