Risk of adverse pregnancy outcomes from SARS-CoV-2 likely lower than previously suggested

The risk of adverse pregnancy outcomes in women who tested positive for SARS-CoV-2 is likely lower than several earlier studies have suggested, a national study of all pregnant Swedish women tested for SARS-CoV-2 between March 2020 and January 2021 reports.

Population-based risk compensation may have been a driving force in UK's COVID pandemic

The COVID-19 pandemic has irreversibly altered our lives in many ways. However, available COVID vaccines are effective against (symptomatic) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, hospitalizations, and even death. Despite a diminishing protective effect against infection and onward transmission after vaccination, and a slightly diminished effect with the Delta variant compared to the Alpha variant, protection against severe outcomes remains high.

UCLA study shows how COVID vaccination is critical to controlling the pandemic

A study currently available on the medRxiv* preprint server has demonstrated that the incidence and mortality rates of coronavirus disease 2019 (COVID-19) in the US can be significantly reduced at the population level by increasing vaccinate rates from 40% to 80%.

A nasal COVID vaccine using a weakened influenza vector

The authors of a new study, published on the bioRxiv* preprint server, constructed a COVID-19 nasal vaccine candidate by inserting a gene encoding the receptor-binding domain (RBD) of the spike protein of SARS-CoV-2, named CA4-dNS1-nCoV-RBD (dNS1-RBD) in a live attenuated influenza virus (LAIV) vector.

Seroprevalence study in Tamil Nadu shows antibody decline following SARS-CoV-2 infection and vaccination

In the sixth-most populated state of India – Tamil Nadu, three rounds of a district-level serological study were conducted through two COVID waves.

Severe COVID-19 patients have significantly higher NK and T cell frequency

A new study published in the open-access journal Cells aimed to clarify the role of NK and T cell subsets in SARS-CoV-2 infection in hospitalized COVID-19 patients to unravel their potential association with disease severity.

Air filter and floor sampling to detect SARS-CoV-2 RNA in schools

A study recently published on the medRxiv* preprint server observed the presence of SARS-CoV-2 RNA in five schools (96 classrooms) in Davis, California (USA), by collecting weekly surface-swab samples from classroom floors and/or portable high-efficiency particulate air (HEPA) units.

Long-term glycemic levels predict the risk of COVID-19 severity among diabetics

People with type 2 diabetes who contract COVID-19 are nearly 50% more likely to wind up in intensive care if they have poorly managed their blood sugar levels over the long-term than those with better long-term glycemic control, according to a study using anonymized health care data.

Study on long-term effects of air pollution on COVID-19 outcomes

A recent study used a spatial ecological design to investigate SARS-CoV-2 infection risk as it relates to air pollution.

Public health measures should be continued alongside covid-19 vaccination, suggest experts

Several personal protective and social measures, including handwashing, mask wearing, and physical distancing are associated with reductions in the incidence covid-19 and should be continued alongside vaccination, suggest experts after reviewing the latest evidence in The BMJ today.
