Investigating the Prevalence of Reactive Online Searching in the COVID-19 Pandemic: Infoveillance Study.
The ongoing pandemic has placed an unprecedented strain on global society, health care, governments, and mass media. Public dissemination of government policies, medical interventions, and misinformation has been remarkably rapid and largely unregulated during the COVID-19 pandemic, resulting in increased misinterpretations, miscommunication, and public panic. Being the first full-scale global pandemic of the digital age, COVID-19 has presented novel challenges pertinent to government advice, the spread of news and misinformation, and the trade-off between the accessibility of science and the premature public use of unproven medical interventions. ⋯ These findings illustrate the increased rate and volume of the public consumption of novel information during a global health care crisis. The positive correlation between mortality and online searching, particularly in countries with lower COVID-19 testing rates, may demonstrate the imperative to safeguard official communications and dispel misinformation in these countries. Online news, government briefings, and social media provide a powerful tool for the dissemination of important information to the public during pandemics, but their misuse and the presentation of misrepresented medical information should be monitored, minimized, and addressed to safeguard public safety. Ultimately, governments, public health authorities, and scientists have a moral imperative to safeguard the truth and maintain an accessible discourse with the public to limit fear.

SARS-CoV-2 and Three Related Coronaviruses Utilize Multiple ACE2 Orthologs and Are Potently Blocked by an Improved ACE2-Ig.
The ongoing coronavirus disease 2019 (COVID-19) pandemic has caused >20 million infections and >750,000 deaths. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of COVID-19, has been found closely related to the bat coronavirus strain RaTG13 (Bat-CoV RaTG13) and a recently identified pangolin coronavirus (Pangolin-CoV-2020). Here, we first investigated the ability of SARS-CoV-2 and three related coronaviruses to utilize animal orthologs of angiotensin-converting enzyme 2 (ACE2) for cell entry. ⋯ In addition, insight into the ability of SARS-CoV-2 and SARS-like viruses to utilize animal orthologs of the SARS-CoV-2 receptor ACE2 might provide structural insight into improving ACE2-based viral entry inhibitors. In this study, we found that ACE2 orthologs of a wide range of domestic and wild animals can support cell entry of SARS-CoV-2 and three related coronaviruses, providing insights into identifying animal hosts of these viruses. We also developed recombinant ACE2-Ig proteins that are able to potently block these viral infections, providing a promising approach to developing antiviral proteins broadly effective against these distinct coronaviruses.

Triggers of mental health problems among frontline healthcare workers during the COVID-19 pandemic in private care homes and domiciliary care agencies: Lived experiences of care workers in the Midlands region, UK.
COVID-19 was first reported in China and later spread across the world causing panic because there is no cure for it. The pandemic has adversely affected frontline health workers and patients, owing to poor preparedness. The study explored the triggers of mental health problems among frontline healthcare workers during the COVID-19 pandemic. ⋯ A thematic approach underpinned by some aspects of interpretive phenomenological analysis (IPA) and the Silences Framework (SF) was utilised. The research found that triggers of mental health problems among frontline health workers in private care homes and domiciliary care agencies are fear of infection and infecting others, lack of recognition/disparity between National Health Service (NHS) and social care, lack of guidance, unsafe hospital discharge, death and loss of professionals and residents, unreliable testing and delayed results and shortage of staff. It is important to support frontline workers in private care homes and domiciliary care agencies.

A key consideration in the Covid-19 pandemic is the dominant modes of transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. The objective of this review was to synthesise the evidence for the potential airborne transmission of SARS-CoV-2 via aerosols. Systematic literature searches were conducted in PubMed, Embase, Europe PMC and National Health Service UK evidence up to 27 July 2020. ⋯ Epidemiological studies suggest possible transmission, with contextual factors noted. Viral particles have been detected in air sampling studies with some evidence of clinical infectivity, and virological studies indicate these particles may represent live virus, adding further plausibility. However, there is uncertainty as to the nature and impact of aerosol transmission of SARS-CoV-2, and its relative contribution to the Covid-19 pandemic compared with other modes of transmission.

The unprecedented nature of the coronavirus pandemic and clinicians' own concerns for safety and stability amidst collective uncertainty have threatened to undermine our ability to trust what we already know about our clients and how to help them. Rather than search for a novel solution, I suggest that what we need during a shared crisis is to renew our trust in the existing ethos of good enough therapy, a metaphoric corollary to Winnicott's concept of good enough mothering, which presupposes the realities of imperfection and uncertainty along the continuum of growth. ⋯ Through the clinical material, I examine opportunities to make use of clients' reactions, as well as my own, in order to deepen the therapeutic process. I discuss the necessity of holding the therapeutic frame with increased flexibility in light of my use of self-disclosure surrounding my COVID-19 diagnosis and recovery, and I assess the impact of this disclosure.
