SARS-CoV-2 spike protein antibodies can persist up to 200 days after symptom onset

Researchers report SARS-CoV-2 antibodies to the spike protein (S protein) can persist 200 days after symptom onset, but that antibodies to the nucleoprotein (N protein) can reduce much more rapidly.

Mefloquine shows potential as anti-SARS-CoV-2 drug

A team of scientists from Japan has identified the approved anti-material drug, mefloquine, as a potential candidate to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Specifically, mefloquine has been shown to prevent the entry of SARS-CoV-2 into host cells and reduce the viral load in vitro.

Digital warm-start CRISPR assay enables sensitive quantitative detection of SARS-CoV-2 in clinical samples

In a recent medRxiv* preprint paper, researchers from the University of Connecticut Health Center in the United States unveil their digital warm-start CRISPR (WS-CRISPR) method for stringent and sensitive quantitative detection of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in clinical samples of patients with coronavirus disease (COVID-19).

Biosensor assay SARS-CoV-2 antibody test may predict COVID-19 severity in patients

Researchers in New York, USA, have found an association of mortality with an early humoral response to SARS-CoV-2 infection within the first few days after onset of symptoms (DAOS), using a highly sensitive and automated testing-on-a-probe (TOP) biosensor assays for SARS-CoV-2.

SARS-CoV-2 RNA best preserved in wastewater under freezing conditions

Wastewater surveillance has been reported to be a feasible and efficient way to monitor the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the current COVID-19 pandemic. A recent study draws attention to the need to freeze wastewater samples if the analysis is carried out later rather than immediately.

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).

Speed of test results and frequency of testing are paramount for effective COVID-19 surveillance

For COVID-19 Surveillance, Test Frequency and Turnaround Time Are Paramount, Modeling Suggests Speed of test results and frequency of testing are paramount for effective COVID-19 surveillance, suggests a new study that modeled trade-offs in test sensitivity, test frequency, and sample-to-answer reporting time, in select scenarios.

SARS-Cov-2 antibodies are detected up to 3 months after infection, shows study

A new study in health care workers led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by "la Caixa" Foundation and the Hospital Clínic of Barcelona, shows that IgA and IgM antibodies to SARS-CoV-2 decay quickly, while IgG antibody levels are maintained for at least three months after infection.

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.
