8/1—Decontamination and reuse of surgical masks and N95 filtering facepiece respirators during COVID-19 pandemic: a systematic review
Fifteen studies and fourteen decontamination methods were identified. Low level of evidence supported 4 decontamination methods, which were ultraviolet germicidal irradiation (9 studies), moist heat (5 studies), microwave generated steam (4 studies), and hydrogen peroxide vapor (4 studies) (Seresirikachorn et al. 2020).
Crisis governance, Chinese style: distinctive features of china’s response to the Covid-19 pandemic
We have illustrated how the Chinese government organized the command structure, steered the bureaucracy, mobilized resources, and carried out community enforcement in response to the outbreak. Clearly, many aspects of the crisis governance style are uniquely Chinese, embedded in the country’s authoritarian system, and socio-economic context.
Risk of COVID-19 among front-line health-care workers and the general community: a prospective cohort study
Among 2 035 395 community individuals and 99 795 front-line health-care workers, we recorded 5545 incident reports of a positive COVID-19 test. Compared with the general community, front-line health-care workers were at increased risk for reporting a positive COVID-19 test (adjusted HR 11·61, 95% CI 10·93–12·33). To account for differences in testing frequency between front-line health-care workers and the general community and possible selection bias, an inverse probability-weighted model was used to adjust for the likelihood of receiving a COVID-19 test (adjusted HR 3·40, 95% CI 3·37–3·43).
Assessment of SARS-CoV-2 Screening Strategies to Permit the Safe Reopening of College Campuses in the United States
In this analytic modeling study, screening every 2 days using a rapid, inexpensive, and even poorly sensitive (>70%) test, coupled with strict behavioral interventions to keep Rt less than 2.5, is estimated to maintain a controllable number of COVID-19 infections and permit the safe return of students to campus. Cost-effectiveness analysis [indicated costs of $470] per student per semester.
Covid-19 is causing the collapse of Brazil’s national health service
Brazil is one of the few countries in the Americas that has free universal healthcare. Today, with gaps in organisation, staff, and public funding, the system has been unable to cope with the sudden load of the rapidly spreading coronavirus, with two million recorded cases of covid-19, more than 80 000 deaths, and a government response that is lacking coordination.
