10/9—Mobile contact tracing in fighting pandemic (COVID-19): Issues, challenges and solutions
We propose an Evaluation framework for mobile contact tracing solutions to determine their usability, feasibility, scalability and effectiveness. We evaluate some of the already proposed contact tracing solutions in light of our proposed framework. Furthermore, we present possible attacks that can be launched against contact tracing solutions along with their necessary countermeasures to thwart any possibility of such attacks (Bashir Dar et al. 2020).
Efficacy of Nationwide Curfew to Encounter Spread of COVID-19: A Case From Jordan
As of 20th June 2020, the total number of cases of COVID-19 in the country was 1,008. Table 1 shows that Jordan has the lowest number of COVID-19 cases compared to other countries in the Middle East. Despite Jordan having the disease before some countries like Turkey and Bahrain and having the disease on the same day as Saudi Arabia, these countries had very high number of cases compared to Jordan.
SARS‐CoV‐2 outbreak investigation in a German meat processing plant
Our results suggest that a single index case transmitted SARS‐CoV‐2 to co‐workers over distances of more than 8 meters, within a confined work area in which air is constantly recirculated and cooled. [This ultimately resulted in] the largest number of confirmed SARS‐CoV‐2 cases in a German meat processing facility reported so far.
Recent endemic coronavirus infection is associated with less severe COVID-19
Four different endemic coronaviruses (eCoVs) are etiologic agents for the seasonal “common cold,” and these eCoVs share extensive sequence homology with human severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Here, we show that individuals with as compared to without a relatively recent documented eCoV were tested at greater frequency for respiratory infections but had similar rate of SARS-CoV-2 acquisition. Importantly, the patients with a previously detected eCoV had less severe coronavirus disease-2019 (COVID-19) illness. Our observations suggest that pre-existing immune responses against endemic human coronaviruses can mitigate disease manifestations from SARS-CoV-2 infection.
US Adults’ Preferences for Public Allocation of a Vaccine for COVID-19
The Figure demonstrates respondents’ high willingness to allocate vaccine preferentially to front-line medical workers (937 respondents [91.6%] rated them high priority), high-risk children (807 respondents [81.0%] rated them high priority), and high-risk older adults (799 respondents [80.6%] rated them high priority). Respondents also reported priority for middle-aged people with higher risk (745 respondents [75.2%] rated them high priority) and for essential (nonmedical) workers (743 respondents [72.0%] rated them high priority).
