Increased incidence and risk of a new diagnosis of diabetes after COVID-19

In a recent study published in the journal BMC medicineresearchers estimate the prevalence of new diabetes after coronavirus disease 2019 (COVID-19). Despite the numerous vaccines and antiviral therapies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the COVID-19 pandemic continues to threaten public health and the economy, with more than 634 million cases and more … Read more

As STIs spread, companies scramble to bring home testing kits to market. But are they reliable?

One of the more remarkable legacies of the Covid-19 pandemic is how quickly federal regulators, health care providers and consumers moved to make home testing a reliable tool for managing a public health crisis. But that rapid focus is missing from another less publicized epidemic: an explosion of sexually transmitted diseases that can cause chronic … Read more

SARS-CoV-2 infection causes reactivation of latent viruses in people with chronic fatigue syndrome

COVID-19 reactivated viruses that had become latent in cells from previous infections, especially in people with chronic fatigue syndrome, also known as ME/CFS. This is the conclusion of a study by Link√∂ping University in Sweden. The results, published in Frontiers in immunologycontribute to our knowledge of the causes of the disease and the prospects of … Read more

Vitamin D may reduce the severity and spread of COVID-19

In a recent study published in the Scientific Reports magazine, researchers in the United States assessed the relationship between vitamin D supplementation and 2019 coronavirus disease (COVID-19) and related mortality. Vitamin D deficiency has long been associated with impaired immune function, which can lead to viral infection. In addition, multiple studies have shown that vitamin … Read more

Hemagglutinin strain immunogens may hold the key to broad protection against influenza A viruses

In a recent article published in Immunityresearchers suggested that vaccines targeting the immunosubdominant but conserved hemagglutinin (HA) strain could elicit broadly neutralizing antibodies (bnAbs) against influenza A viruses. Study: Co-immunization with hemagglutinin strain immunogens elicits cross-group neutralizing antibodies and broad protection against influenza A viruses.
