Study finds that patients with systemic autoimmune rheumatic diseases had a lower antibody response than healthy controls after Omicron infection

Study investigated if patients with systemic autoimmune rheumatic diseases (SARDs) have a reduced immunological response.

27 Jul 2023

Study provides valuable insights into the UV susceptibility of SARS-CoV-2 omicron variants

The global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its new variants has created a need for effective disinfection technologies to protect against harmful pathogens.

27 Jul 2023

Heterologous booster schedules are associated with increased protection against severe, omicron related COVID-19 outcomes

Study compared different coronavirus disease 2019 (COVID-19) vaccination regimens.

26 Jul 2023

Widespread vaccination needed to protect adults from serious and moderate COVID-19 disease

An analysis of real-world data from more than 1.2 million patients from health systems in four geographically dispersed states -- Indiana, Oregon, Texas and Utah -- conducted by the U.S. Centers for Disease Control and Prevention's VISION Network, has determined both the number of adults needed to be vaccinated to prevent one COVID-19 associated hospitalization and the number needed to be vaccinated to prevent one COVID-19 associated emergency department (ED) visit.

Characterizing the concentration and binding affinity of WT–induced antibodies against the Omicron subvariant BA.1

A recent study characterized the concentration and binding affinity of antibodies induced by SARS-CoV-2 WT strain against the Omicron subvariant BA.1.

This fortnightly flu and COVID-19 report brings together the latest surveillance data along with the latest public health advice.

21 Jul 2023

A model-based approach to estimating vaccine effectiveness against SARS-CoV-2 variants of concern

A group of researchers examined the effectiveness of updated vaccines and variant-matched boosters.

21 Jul 2023

Trypsin and anaerobic bacteria boost SARS-CoV-2 Delta variant infectivity: oral hygiene key to prevention

Researchers investigated whether trypsin, a protease, increased SARS-CoV-2 infectivity.

21 Jul 2023

Comparing severe outcome risks of SARS-CoV-2 Omicron BA.2.75, BQ.1, BA.4.6 to BA.5

Researchers determine the clinical severity of SARS-CoV-2 Omicron sub-lineages BA.4.6, BQ.1, and BA.2.75 relative to BA.5.

Researchers investigated early biomarkers of post-acute sequelae of SARS-CoV-2 infection in individuals intensively sampled during the acute phase of COVID-19.

20 Jul 2023

Study provides new insights into how SARS-CoV-2 affects glucose metabolism

Research conducted at the University of São Paulo (USP) in Brazil shows that SARS-CoV-2, the virus that causes COVID-19, can infect liver cells (hepatocytes), stimulating glucose production and leading to a condition similar to diabetes (hyperglycemia) in hospitalized patients, even if their blood sugar level was normal before they were admitted to hospital.

19 Jul 2023

Vaccine hesitancy and lack of healthcare access led to higher COVID-19 deaths in rural areas

There was one striking difference between 2020, year one of the COVID-19 pandemic, and 2021, year two: in the second year, vaccines became readily available.
