NewsNew study highlights scale and impact of long COVID
A wide range of biological mechanisms are involved in long Covid, including persistence of the original virus in the body, disruption of the normal immune response, and microscopic blood clotting, even in some people who had only mild initial infections.
-
NewsCEPI and WHO urge broader research strategy for countries to prepare for the next pandemic
The Coalition for Epidemic Preparedness Innovations (CEPI) and the World Health Organization (WHO) today called on researchers and governments to strengthen and accelerate global research to prepare for the next pandemic.

NewsNasal COVID-19 vaccine halts transmission
Next-generation Covid vaccines that target the virus’s points of entry — the nose and mouth — may be able to do what traditional shots cannot: contain the spread of respiratory infections and prevent transmission.

NewsWhat shapes a virus’s pandemic potential? SARS-CoV-2 relatives yield clues
Two of the closest known relatives to SARS-CoV-2 — a pair of bat coronaviruses discovered by researchers in Laos — may transmit poorly in people despite being genetically similar to the COVID-19-causing virus, a new study reveals.
-
NewsIncidence of heart attacks and strokes found to be lower after COVID-19 vaccination
A new study involving nearly the whole adult population of England has found that the incidence of heart attacks and strokes was lower after COVID-19 vaccination than before or without vaccination.
-
NewsResearchers identify structural characteristics of newly emerged SARS-CoV-2 variants
A new study has revealed the spike (S) protein structures of the recently emerged BA.2.86, JN.1, EG.5, EG.5.1 and HV.1 subvariants of SARS-CoV-2, and conducted systematic comparative analysis on these subvariants.
-
NewsVirus that causes COVID-19 is widespread in wildlife
Six out of 23 common wildlife species showed signs of SARS-CoV-2 infections in an examination of animals in Virginia, as revealed by tracking the virus’s genetic code.
-
NewsInter-variant recombination, genomic perspectives and pathogenicity of emerging sub-variants of Omicron
A review highlights recent updates on newly identified Omicron sub-variants, focusing on their genomic alterations, infectivity patterns, and pathogenic manifestations.
-
NewsMild COVID-19 can cause long-term cognitive losses
Although the damage caused by SARS-CoV-2 was most intense among those who had severe COVID-19, some had memory loss and attention deficit more than 18 months after being infected, even though they had not needed to be hospitalized.
-
NewsWearable health sensors are a powerful tool in disease detection
When seemingly healthy people receive an alert from a wearable sensor telling them they might have a respiratory virus, only a quarter of people follow up such an alert with an at-home viral test, according to a new study.
-
NewsScientists uncover genes that contribute to severe COVID-19 susceptibility
Researchers confirmed the central and already known role of the TLR7 gene in severe courses of the disease in men, but were also able to find evidence for a contribution of the gene in women.
-
NewsFinding a solution for long COVID, one cell type at a time
A 2022 study suggesting that blocking a single molecule could protect against severe illness in COVID-19 has led to a $15 million federal grant supporting a comprehensive effort to learn more – with finding a solution to long COVID at the center of the new research.
-
NewsMini lungs make major COVID-19 discoveries possible
Scientists infect miniature lung organoids with the virus responsible for COVID-19, revealing new ways in which the infection spreads and suggesting potential treatments.

NewsWearing a face mask in public spaces cuts risk of common respiratory symptoms, study suggests
Wearing a surgical face mask in public spaces reduces the risk of self-reported respiratory symptoms, finds a trial of adults in Norway.
-
NewsSARS-CoV-2 pandemic increases maternal deaths from non-respiratory causes, study finds
A new study revealed a significant impact of the COVID-19 pandemic on maternal mortality in Chile. The pandemic did not affect direct obstetric deaths such as hemorrhage, sepsis and abortion, but non-respiratory indirect obstetric causes increased the most.
-
NewsNirmatrelvir/ritonavir antiviral combination shows potential in reducing COVID-19 hospitalizations
A systematic review aimed to summarize published evidence on the efficacy, effectiveness, and safety of nirmatrelvir/ritonavir for COVID-19. The review also intended to assess the robustness of the evidence from randomized controlled trials.
-
NewsMutations of the spike gene do not predict the severity of variants of SARS-CoV-2
The two recent and prevalent strains of the virus that cause COVID-19 are not significantly better than their predecessor Omicron at evading immune responses and causing infections despite having a higher number of mutations.
-
NewsScientists investigate effectiveness of non-pharmaceutical interventions against pathogens
Scientists have investigated the success of non-pharmaceutical interventions, analysing almost two million SARS-CoV-2 genomes that occurred in the German population during the years of the pandemic.

NewsNew ECDC Director Pamela Rendi-Wagner emphasises importance of restoring public trust in science after pandemic
Incoming ECDC Director Dr Pamela Rendi Wagner has outlined her vision for the agency, highlighting the challenges to public health after the COVID-19 pandemic, including war in Europe, climate change, and increasing social inequalities.

NewsStudy identifies unpredicted immune responses to adenoviral COVID vaccines
Researchers have identified unpredicted T-cell immune responses to the adenoviral (Oxford/AstraZeneca and Janssen) COVID-19 vaccines, but not to the mRNA vaccines.
