Robust passive and active immunity found in infants born to COVID-19 positive mothers

A new study provides evidence that babies born to mothers who were COVID-19 positive two or more months before delivery are protected by maternal antibodies, besides mounting a robust immune response in case they contract the infection in the perinatal period.

Researchers demonstrate real-world effectiveness of Johnson & Johnson COVID-19 vaccine

Researchers in the United States and India have conducted a study demonstrating the real-world effectiveness of a single dose of Johnson & Johnson’s Ad26.COV2.S vaccine at preventing infection with severe acute respiratory syndrome coronavirus 2 – the agent that causes coronavirus disease 2019 (COVID-19).

Researchers identify novel SARS-CoV-2 variant with mutations in membrane protein-encoding gene

A recent study published in the Journal Emerging Microbes and Infections has highlighted the emergence of a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant with mutations in the membrane protein-encoding gene. Two potential mutations, M:I82T and M:V70L, have been identified within the transmembrane helices, which are expected to improve viral fitness by modulating glucose uptake during replication.

Hepatitis C antivirals synergize with remdesivir to inhibit SARS-CoV-2 in vitro

A new study sheds light on the potential of drug combinations to stem viral transmission and treat patients with COVID-19. It also shows that four drugs used to treat hepatitis C synergize with remdesivir to make it up to ten times more effective at inhibiting SARS-CoV-2 in cell cultures.

Could COVID-19 rapid antigen tests aid international border control measures?

A recent study has explored the use of rapid antigen testing for COVID-19 at borders to reduce community transmission, and concluded that it would be effective only at lower volumes of passenger traffic.

Researchers review materials used to design biosensors for SARS-CoV-2 detection

The SARS-CoV-2 virus is still causing a dramatic loss of human lives worldwide, constituting an unprecedented challenge for society, public health, and economy, to overcome. Currently, SARS-CoV-2 can be diagnosed in two different ways: i) antigen tests (point-of-care, POC) and ii) molecular tests (nucleic acid, RNA, or PCR-polymerase chain reaction).

Is Hong Kong’s fourth wave of COVID-19 due to the Q57H SARS-CoV-2 variant?

A recent article in the Centers for Disease Control and Prevention (CDC)’s Emerging Infectious Diseases reveals that the last of these was probably due to the introduction of a new variant from Nepal. This novel variant had been circulating in the community for about a month before the last outbreak was reported.

Israel study suggests elementary school reopenings are low-risk for COVID-19 transmission

Ever since COVID-19 first emerged with devastating ferocity, the emphasis has been on interrupting its spread until effective, safe and targeted antivirals and vaccines become available. The chief focus has been on non-pharmaceutical interventions (NPIs), including school closures, social distancing and shelter in place orders.
