Exposure to air pollutants (PM2.5 and PM10) is associated with an increased risk of persistent long-Covid symptoms, partly due to its impact on the severity of the acute infection, a new study shows.
After a Covid-19 infection, patients may suffer from a variety of symptoms, including difficulty concentrating (“brain fog”). New research now linked the condition to impaired lung function.
People who have been fully vaccinated against Covid-19 have a significantly lower risk of developing more severe cardiovascular conditions linked to Covid-19 infection, a new study shows.
Many aspects of long Covid are still poorly understood, so many sufferers have turned to self-monitoring via wearables. New research explores the benefits and drawbacks of this approach.
Immunocompromised patients are at greatest risk of developing severe Covid-19 after an infection. While early antiviral treatments yield best results, even late-onset therapies still show benefits.
Protection from established Covid-19 vaccines wanes relatively quickly. A new vector vaccine elicits prolonged immune response in animal models, and maintains its efficacy over extended time.
Brazilian researchers have identified a key mechanism of Sars-CoV-2 to manipulate its host’s immune defense. This discovery could pave the way for the development of novel therapies.
When point-of-care testing (POCT) models for diagnosing infectious disease are effective, the quality of pathology results can be equivalent to laboratory tests, new research shows.
Burnout, fear of infection, lack of support: One in three doctors and nurses considered leaving their job, or the healthcare profession altogether, during the Covid-19 pandemic, a new study shows.
A new approach to vaccine development could produce vaccines before the disease-causing pathogen – such as a new variant of the coronavirus Sars-CoV-2 – even emerges.
New research provides cause for optimism that long Covid can resolve over time. Following people from the first wave of Covid-19, it monitored the longevity of immune abnormalities after an infection.
Findings from the largest UK study of patients hospitalised with Sars-CoV-2 infection show that long Covid leads to ongoing inflammation which can be detected in the blood.
A recent suggestion to stop using the term ‘long-Covid’ may have been well-intentioned, but could ultimately do more harm than good, experts point out.
Using ultrasound imaging to detect Covid-19 infections, a new automated detection tool could help doctors in the emergency room diagnose patients quickly and accurately.
Patients who are suffering from aftereffects of a coronavirus infection often receive the diagnosis 'long Covid'. However, new research presented at ECCMID 2024 calls that term into question.
New study results explore the long-term effects of infection with Sars-CoV-2, and challenge the idea that vaccine immunity fades quickly.
How does a coronavirus infection cause neurological symptoms such as headaches, memory problems, and fatigue? A new study points to a different reason than previously assumed.
During the Covid-19 pandemic, Switzerland relied on contact tracing to identify people likely to have been contaminated by an acquaintance. A research team assessed the effectiveness of this method.
Researchers from the University of Southampton investigated how ultraviolet laser light destroys the coronavirus Sars-CoV-2 by impacting components critical for infection.
A new, large-scale study from Sweden underlines the importance of vaccination against Covid-19: The research shows that an infection raises the risk of heart rhythm disturbances.
Using diffusion MRI technology, researchers in Sweden have found differences in brain tissue structure between patients with persisting symptoms after Covid-19 and healthy people.
Being overweight – not just being obese – can increase Covid-19 severity. the elevated BMI creates an impaired antibody response to SARS-CoV-2 infection but not to vaccination, new research finds.
The Covid-19 pandemic has affected scientific research in numerous ways – for example by highlighting knowledge gaps in gender medicine. In many studies differences in morbidity and mortality between women and men surfaced incidentally. While the extent and causes of these differences remain largely unexplored, the preliminary insights confirm the need for further research.
Researchers have developed a method for assessing the number and structure of aggregated blood platelets (or thrombocytes) that can potentially help quantify the risk of a severe Covid-19 infection. As a result, they have identified a predictive biomarker for the seriousness of a Covid-19 infection. This will allow physicians to adjust treatment at an early stage. The researchers used a method…
A mechanism that led some patients to experience cases of deadly clotting following some types of Covid-19 vaccination has been identified in new research.
