Testing reveals 11 percent of people in Geneva infected with SARS-CoV-2

Now, a team of researchers at Geneva University Hospitals has found that less than 11 percent of the population in Geneva has contracted the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Their research is published in the journal The Lancet.

BCG vaccination strengthens the immune system

A tuberculosis vaccine developed 100 years ago also makes vaccinated persons less susceptible to other infections. While this effect has been recognized for a long time, it is not known what causes it.

Combination of nelfinar and amodiaquine shows promise for treating COVID-19

Six months into the COVID-19 pandemic, more than 7.4 million people have been infected, and more than 410 000 have died. As yet, there is no treatment or vaccine for the disease.

Tuberculosis and polio vaccines may offer temporary protection against SARS-CoV-2

As the world grapples with the coronavirus disease (COVID-19) pandemic, scientists race to develop an effective vaccine to protect against the deadly SARS-CoV-2 virus. While potential vaccines are still being developed and tested, researchers propose that existing vaccines could give the immune system a temporary boost to ward off infection.

Glycans "lock and load" the SARS-CoV-2 spike protein for infection

A new study by scientists from the University of California San Diego, USA and Maynooth University, Ireland and published on the preprint server bioRxiv* in June 2020 reports preliminary results showing that the spike protein of the SARS-CoV-2, as well as its glycan coat, has “hitherto unseen functional and structural” properties. These may be useful in designing novel therapeutics to target this molecule.

Early neutralizing response to SARS-CoV-2 dominated by IgA antibodies

Researchers from France and the U.S. demonstrated how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection could induce an early and vigorous virus-specific IgA response that paves the way for the production of SARS-CoV-2 IgG antibodies, with even better neutralizing properties. Their paper is currently available on the medRxiv preprint server.

Beta adrenergic agonists can help decrease risk of graft vs. host disease in alloBMT recipients

New preclinical work by a team of researchers from Roswell Park Comprehensive Cancer Center's Transplant and Cellular Therapy Program suggests that the risk of developing acute graft vs. host disease during allogeneic blood/marrow transplant - a potentially curative treatment for selected patients with hematologic disorders - can be decreased using an existing class of drugs called beta adrenergic agonists.

Study: Only a minority of Geneva population has been infected by Covid-19 pandemic

A study carried out among 2'766 people by the University Hospitals of Geneva (HUG), the Geneva Centre for Emerging Viral Diseases, and the University of Geneva (UNIGE), Switzerland, reveals that, at the time of the decline of the Coronavirus pandemic, only 10.8% of the Geneva population had been infected with Covid-19.

Type III interferons can increase risk of bacterial "superinfections" in the lung, research shows

Interferons and other cytokines produced by the immune system are important defenses against viral infections, but as we have seen in COVID-19, they can also contribute to damaging, potentially life-threatening lung inflammation.
