Covid19-Sources

Upon SARS-CoV-2 infection, most individuals develop neutralizing antibodies and T-cell immunity. However, some individuals reportedly remain SARS-CoV-…

Large-scale population screening can provide insights to levels of ongoing SARS-CoV-2 transmission. Here, the authors report a citywide screening of ~10,000,000 residents of Wuhan and show that SARS-CoV-2 infection prevalence was very low five to eight weeks after the end of lockdown.

Keys to an effective COVID-19 vaccination program

Cells in the nasal passages and upper airways are likely the coronavirus' major point of entry into the body, according to a study by Stanford Medicine researchers.

Profound data on adolescent health literacy are needed as a requirement for the development of health literacy promoting interventions. This paper aims to study the level of generic health literacy among adolescents and to explore associations between health literacy and socio-demographic (age, sex, family affluence, migration background), social (social support by family and friends) and personal (self-efficacy) factors. We conducted a representative cross-sectional online survey. Four health literacy dimensions were captured among 14–17 years old adolescents living in Germany (n = 1...

Social distancing guidelines go against our deepest instincts and cultural norms. Can we overcome that as a society?

Large-scale containment measures that reduce the spread of COVID-19 have proven to have too large an impact on both the economy and our mental health to be sustainable in the long term. Here, the authors show that travel reductions between geographical regions and timely local control measures can reduce the region-to-region reproduction number below one, thus eliminating the epidemic and preventing recurrent waves without the need for long-term lockdown measures.

Weibull ist sehr ähnlich zu lognormal Verteilung.Sie wird gerne bei Ausfallstatistiken (z.B. stressbedingtem Ausfall) benutzt und war auch hier benutzt:https://t.co/gujeFd3iX1— Dave (@icestormfr) November 24, 2020

Most Covid-19 infections are spread by people who have no symptoms, the CDC says in newly updated guidance.

Background: Since the first wave of COVID-19 in March 2020, people returning to New Zealand have been required to undergo managed isolation and quarantine (MIQ) for 14 days with mandatory testing for SARS-CoV-2. As of 20 October, testing in MIQ had identified 215 cases of SARS-CoV-2 from a total of 62,698 arrivals. While the majority of infections were likely obtained in the country of origin prior to departure, there have been possible reports of in-flight transmission. Methods: Seven people who arrived in New Zealand on the same flight on 29 September tested positive during their stay in ...

The immune system is complex and involves many genes, including those that encode cytokines known as interferons (IFNs). Individuals that lack specific IFNs can be more susceptible to infectious diseases. Furthermore, the autoantibody system dampens IFN response to prevent damage from pathogen-induced inflammation. Two studies now examine the likelihood that genetics affects the risk of severe coronavirus disease 2019 (COVID-19) through components of this system (see the Perspective by Beck and Aksentijevich). Q. Zhang et al. used a candidate gene approach and identified patients with sever...

After losing its initial grip on Covid, Australia is again being hailed as a global success story.

Uruguay has a rolling number of just over 3,000 confirmed cases and 59 total recorded deaths — the lowest mortality rate in Latin America. So how did the nation defy the odds? Hayley Henderson explains.

COVID-19 has swept across the world, overwhelming healthcare systems and raising countless questions about how best to diagnose patients, treat infections, save lives, and contain the pandemic. In short order, researchers have launched randomized trials to uncover pharmacologic interventions that hold the promise of preventing or lessening the severity of the disease. But getting results takes time. And time was a luxury that doctors on the frontlines of the coronavirus fight could ill afford in the early months of the pandemic. The dangers of COVID-19 present an unprecedented opportunity t...

Wissenschaftler und Ärzte um den Bonner Virologen Hendrik Streeck fordern eine Abkehr von der bisherigen Strategie.

Dreimal so viele Tests wie im Frühjahr und gleichzeitig steigende Neuinfizierten-Zahlen: Gibt es einen Zusammenhang? Experten bezeichnen die Frage nach der Höhe der Dunkelziffer als "Millionen-Frage".

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is closely related to the deadly coronaviruses SARS-CoV-1 and Middle East respiratory syndrome coronavirus (MERS-CoV). Considerable efforts are focused on developing treatments, and therapies that work across coronaviruses would be particularly valuable. Shedding light on the host factors hijacked by the viruses, Gordon et al. mapped the interactions between viral and human proteins for SARS-CoV-2, SARS-CoV-1, and MERS-CoV; analyzed the localization of viral proteins in human cells; and used genetic screening to identify host fact...

Antibody-dependent enhancement (ADE) has been reported in several virus infections including dengue fever virus, severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) coronavirus infection. To study whether ADE is involved in COVID-19 infections, in vitro pseudotyped SARS-CoV-2 entry into Raji cells, K562 cells, and primary B cells mediated by plasma from recovered COVID-19 patients were employed as models. The enhancement of SARS-CoV-2 entry into cells was more commonly detected in plasma from severely-affected elderly patients with high titers of SARS-CoV-2 ...
