Researchers identify molecular determinants of prolonged COVID-19 post-infection

Researchers identify molecular determinants of prolonged COVID-19 post-infection

In a recent study published in the journal Natural medicineinvestigators presented a whole-transcriptome assessment of changes in blood gene expression that occur in acute COVID-19 (coronavirus disease 2019) and are associated with PASC (post-acute sequelae of COVID-19), commonly known like prolonged COVID-19. PASC comprises a wide range of symptoms such as fatigue, dyspnea, and taste/smell … Read more

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

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

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

A large COVID vaccination study found that thrombosis and thrombocytopenia are very rare complications.

A large COVID vaccination study found that thrombosis and thrombocytopenia are very rare complications.

In a recent nature communications In a journal article, investigators determine rates of thrombosis, thrombocytopenia, and thrombosis with thrombocytopenia after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination and infection. These rates were compared to background (expected) rates assessed in the UK general population. To study: Thrombosis and thrombocytopenia following vaccination and SARS-CoV-2 infection in … Read more

All eligible people urged to get vaccinated due to higher than usual flu case rates

All eligible people urged to get vaccinated due to higher than usual flu case rates

All those eligible for the flu vaccine have been urged to come forward as cases rise to levels not seen since before the pandemic. So far this year, uptake of the influenza vaccine in eligible groups is similar to that of recent years, although there is a particular need for preschool-age children, pregnant women, and … Read more
