Study examines risk of new onset diabetes mellitus following SARS-CoV-2 infections

In a recent study posted on the medRxiv* preprint server, researchers evaluated individuals with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and who were diagnosed with diabetes mellitus within six months of the onset of the 2019 coronavirus disease (COVID-19) to assess the temporal relationship between SARS understand -CoV-2 infections and diabetes mellitus. Study: … Read more

To feel sick? How do you know if you have COVID, RSV or the flu?

It’s a triple threat. After years of isolating and masking, flu, COVID-19, and respiratory syncytial virus (RSV) are all hitting harder and earlier this cold season in a phenomenon called a “triple-demics.” About 20,000 Americans were hospitalized with the flu during Thanksgiving week, the highest number that week in more than 10 years, according to … Read more

How did the seasonal patterns of RSV infections in 2022 compare to those of other COVID-19 pandemic and pre-pandemic years?

In a recent study posted on the medRxiv*preprint server, researchers assessed the impact of the 2019 coronavirus disease (COVID-19) pandemic on the seasonal patterns of RSV (respiratory syncytial virus) infections in young children living in the US (United States). Study: Seasonal confounding, patient characteristics, and disparities of respiratory syncytial virus infection in young children in … Read more

Human T-cell immunity faces worrying mutations in SARS-CoV-2 variants

Immune T cells continue to target the spike protein of SARS-CoV-2 variants of concern, although mutations make some T cells less effective, according to new research. Published in Nature Immunologyresearchers at the University of Birmingham have shown that human T-cell immunity is currently related to mutations that have accumulated over time in COVID-19 variants. In … Read more

More than half of American adults were not worried about flu season, research shows

With flu-related hospitalizations rising to record early-season levels, the American Heart Association, a global force for longer, healthier lives for all, is concerned that many people will be caught off guard by this health threat and urges on rapid vaccination against the virus. According to a survey conducted by The Harris Poll commissioned by the … Read more

The evolutionary pathways and mechanisms driving the emergence of post-Omicron SARS-CoV-2 lines

In a recently published report on Virological*, a discussion forum for virus genome analysis, researchers summarize the mechanisms by which the novel Omicron sublines of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) evolve. Study: SARS-CoV-2 evolution, post-Omicron. Image credit: Jezper/Shutterstock Background Over time, SARS-CoV-2 has shown a unique evolutionary trait called saltation: the ability … Read more

Monkeypox renamed “mpox” in an effort to combat stigma

As of November 29, 2022, the World Health Organization (WHO) has announced that the monkeypox virus will now be referred to as “mpox” in an effort to reduce the stigma associated with this condition. Image credit: Berkay Ataseven / “mpox” Since the onset of the current mpox outbreak in numerous non-endemic regions around the … Read more

New biosensing platform detects SARS-CoV-2 antibodies in five minutes

Rapid, cheap and accurate testing remains essential for epidemiological surveillance and for health services to monitor and contain the spread of SARS-CoV-2. Brazilian scientists have contributed to efforts in this area by developing an electrochemical immunosensor that detects antibodies against the virus. The innovation is described in an article that recently appeared in the journal … Read more

How do COVID-19 outcomes differ by race and gender?

In a recent study published in PLOS ONEresearchers examined the variations in testing for coronavirus disease 2019 (COVID-19) and severe outcomes based on race, ethnicity and gender. Study: Differences in COVID-19 Testing and Adverse Outcomes by Race, Ethnicity, Gender, and Health System in a Large, Diverse US Cohort. Image credit: blvdone/Shutterstock Background Early results indicate … Read more

How SARS-CoV-2 immune responses vary by population due to environmental and genetic factors

Severe acute respiratory syndrome with coronavirus 2 (SARS-CoV-2) infected individuals show a wide range of clinical variations, from asymptomatic infection to fatal disease. In a recent study published on the bioRxiv* preprint server and an international team of researchers investigated the genetic, immunological and evolutionary factors that determine the vast variability observed in clinical manifestations … Read more
