Cognitive impairment as a result of severe Covid-19 is similar to that sustained between 50 and 70 years of age and is the equivalent to losing 10 IQ points, scientists found.
Six in ten people with Covid-19 still have at least one symptom a year later, a new study has found. Furthermore, symptoms that don’t clear up after 15 weeks are likely to last at least a year.
Using mass spectrometry and chromatography techniques, UK researchers have developed an approach to predict infection severity among Covid-19 patients, as well as potential outcomes.
A global analysis of nearly 6 million Covid-19 deaths finds an increase in mortality at weekends compared to weekdays. Bureaucratic and reporting delays alone do not explain this, researchers report.
By comparing the infectious viral load caused by ancestral SARS-CoV-2 as well as by the Delta and Omicron variants, scientists highlight the benefits of vaccination.
A platform for studying how the human immune system responds to hepatitis C infection by combining microfluidic technology with liver organoids could speed the hunt for a vaccine.
COVID-19 measures such as school closures and ‘high-traffic and mixing’ areas had the strongest association, providing clues for new intervention approaches.
The tool has made it possible to detect SARS-CoV-2 in exudate from symptomatic patients with a sensitivity of 100% and a specificity of 87.5%
Scientists have confirmed that an inhaled form of COVID vaccine can provide broad, long-lasting protection against the original strain of SARS-CoV-2 and variants of concern.
Researchers have developed an inexpensive, non-toxic coating for almost any fabric that decreases the infectivity of the virus that causes COVID-19 by up to 90 per cent.
Scientists have investigated the effectiveness of various common hand disinfectants against hepatitis E. They were able to show that most formulations do not completely inactivate the virus.
Researchers have developed a device that removes one of the biggest bottlenecks preventing quick, reliable malaria diagnosis.
A connection between the Epstein-Barr virus and multiple sclerosis has long been suspected. A new study provides ‘compelling evidence of causality’.
In both the mice and organoids, cytokines suppressed tumor growth after treatment, and defense cells migrated to the brain region affected by the tumor, alerting the immune system to its existence.
Researchers have developed a diagnostic for SARS-CoV-2 that is capable of differentiating between COVID-19 and the garden-variety bug with fast turnaround.
Scientists at have designed a quantum sensor to detect SARS-CoV-2 faster, cheaper, and more accurate than the current gold-standard technique, PCR.
An international team of scientists have identified antibodies that neutralize omicron and other SARS-CoV-2 variants.
In experiments using saliva samples from COVID-19 patients, the gum, which contains the ACE2 protein, neutralized the virus.
A new rapid molecular diagnostic test from Cepheid has received the CE mark for distribution in the European market. The test, called Xpert Xpress CoV-2/Flu/RSV plus, is designed for qualitative detection of the viruses causing Covid-19, Flu A, Flu B, and respiratory syncytial virus (RSV) infections from a single patient sample. The new plus version of the test provides a third gene target for…
Researchers have found a possible explanation for why some patients recover much more poorly from brain injury if they later become infected.
Study suggests need for better ventilation and tight-fitting masks, in addition to widespread vaccination to help stop spread of the virus.
Researchers have found a way to defeat the multi-resistant bacterium Mycobacterium abscessus, a relative of the causes of tuberculosis and leprosy.
To better prepare and protect the world from global disease threats, H.E. German Federal Chancellor Dr Angela Merkel and Dr Tedros Adhanom Ghebreyesus, World Health Organization (WHO) Director-General, have inaugurated the new WHO Hub for Pandemic and Epidemic Intelligence, based in Berlin.
Viruses do not always kill the cells they infect. Researchers at the University of Basel have discovered in experiments with mice that cells have the power to self-heal and eliminate viruses. However, these cells undergo long-term changes. The findings may provide a hint as to why cured hepatitis C patients are more susceptible to liver cancer for years after.
To date, there are no effective antidotes against most virus infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell…
