Chicago seroprevalence study shows COVID-19 cases 16 times higher than currently predicted

A startling new case study of Chicago, led by a team of researchers at Northwestern University in Illinois, USA, suggests a 16-fold higher incidence of SARS-CoV-2 infection than previously thought. This is judging from seroprevalence (antibody presence blood testing) figures, rather than the number of RT-PCR-positives reported there (via swab sample testing of symptomatic patients).

Analysis shows social distancing helped reduce nosocomial SARS-CoV-2 transmission in London

Recently, a team of researchers from the King's College London, Guy's and St Thomas' NHS Foundation Trust, and St Thomas' Hospital, London analyzed comprehensive epidemiological and viral nanopore sequence data from 574 patients with SARS-CoV-2 infection confirmed by a PCR test in March 2020.

Study characterizes early chains and patterns of COVID-19 transmission in France

By using data from epidemiological investigations and contact-tracing efforts during the initial phase of the coronavirus disease (COVID-19) epidemic in France, researchers were able to appraise secondary clinical attack rates and factors associated with the risk of a contact becoming a case. Their findings are currently available in a medRxiv preprint paper.

COVID-19 potentially has negative impacts on male fertility

A review recently published in the Journal of Medical Virology has discussed some of the effects that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – may have on male fertility.

Sage and perilla herbal teas could help to prevent or treat COVID-19

Researchers in Germany have conducted a study demonstrating the potential antiviral effects of commonly consumed herbal teas on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the pathogen that causes coronavirus disease 2019 (COVID-19).

SARS-CoV-2 suppresses ACE2 activity in COVID-19 patients

A recent study conducted by a team of international scientists has revealed that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19), suppresses the expression and function of human angiotensin-converting enzyme 2 (ACE2) and induces the expression of interferon-stimulated genes at the initial phase of infection. The study is currently available on the bioRxiv* preprint server.

Food products are potential SARS-CoV-2 carriers, study finds

A team of scientists at the Shahid Beheshti University of Medical Sciences and the Food Safety Research Center in Iran has emphasized the risk of various staple food products, including meat, dairy, fruits, vegetables, and ready-to-eat foods, as potential carriers of SARS-CoV-2 transmission.

How effective have COVID-19 mitigation strategies been in Australia's second wave?

Researchers have modeled the effect of the different types of social distancing implemented in Australia's greater Melbourne area in response to the county's second wave of coronavirus disease 2019 (COVID-19) cases. They found implementing stricter lockdowns in the beginning before the rapid rise in cases works best. The team's findings have been made available on the preprint server, medRxiv*.

Universal screening for SARS-CoV-2 may be an ineffective mitigation strategy, says study

A team of researchers in the Netherlands have reported that regular, universal and random screening and isolation of infectious individuals may not be a viable strategy for reopening society after bringing a wave of SARS-CoV-2 under control.

Sinovac Biotech's COVID-19 vaccine candidate triggers immune response

Now, Sinovac Biotech's candidate vaccine, CoronaVac, has been found to induce an immune response in healthy adults aged 18–59 years, 28 days post-vaccination. However, the level of antibodies generated was lower than in people who had recovered from the illness.

Mosaic RBD nanoparticles elicit neutralizing antibodies against SARS-CoV-2

The researchers show that the mice immunized with homotypic or mosaic nanoparticles produced broad binding and neutralizing responses, in contrast to plasma antibodies elicited in humans by SARS-CoV-2 infection. The RBD nanoparticles induced cross-reactive IgG responses in the immunized mice.
