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).

Study suggests neutralizing SARS-CoV-2 antibodies offer protection against reinfection

A new study published in November 2020 on the preprint server medRxiv* indicates that the chances of symptomatic infection are indeed much lower among the population with antibodies to the virus.

Seroprevalence meta-analysis predicts 643 million already infected by SARS-CoV-2 globally

A recent systematic review and meta-analysis conducted by a team of international scientists reveal low seroprevalence of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in the general population.

Detectable SARS-CoV-2 antibodies 120 days post-infection in Chicago case study

In a recent study, a team of researchers at Northwestern University, USA, had found that nearly 20 percent seroprevalence in the United States metropolitan site, Chicago, over the summer, during a period when lockdown restrictions were eased. They found that three-quarters of seropositive individuals retained detectable antibodies for at least 120 days or four months.

Males may have higher but more transient SARS-CoV-2 immunity than females post-infection

Adding another piece to the puzzle that is coronavirus disease 2019 (COVID-19) serology, a new study published on the preprint server medRxiv* in November 2020 suggests that males have stronger but more transient anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) protective immunity than females.

Difference in antibody evolution could predict COVID-19 outcomes

For COVID-19, the difference between surviving and not surviving severe disease may be due to the quality, not the quantity, of the patients' antibody development and response, suggests a new Cell paper published by Galit Alter, PhD, a member of the Ragon Institute of MGH, MIT and Harvard.

New saliva-based test found to accurately detect the presence of SARS-CoV-2 antibodies

A new saliva-based test developed by a team at Johns Hopkins Bloomberg School of Public Health has been found to accurately detect the presence of antibodies to SARS-CoV-2, the virus that causes COVID-19, from small samples of saliva, according to a study led by Bloomberg School researchers.

Research shows a unique T cell receptor repertoire in MIS-C patients

Children with coronavirus disease 2019 (COVID-19) sometimes develop the Multisystem Inflammatory Syndrome in Children (MIS-C), which is associated with high morbidity. The underlying T-cell associated mechanism is described by researchers in a new study published on the preprint server bioRxiv in November 2020, as a response to superantigen activation.

Seroprevalence and immune response to SARS-CoV-2 in Paris

François Anna et al. published this study in a recent medRxiv* preprint paper, where they present the results of assessing the serological response in the selected population. They tested for specific IgG response against the SARS CoV-2 Nucleoprotein and Spike protein and performed a pseudo-neutralization assay in sera of urban dwellers in Paris.
