Omicron appears more deadly than seasonal influenza, study suggests
Adults hospitalised with the SARS-CoV-2 Omicron variant have a higher death rate than those hospitalised with seasonal influenza, even though Omicron is considered less virulent with lower case fatality rates than the delta and alpha strains, new research being presented at ECCMID suggests.

Mask rule in hospitals may have little impact on COVID-19 transmission during Omicron wave
A study in large London hospital during first 10 months of Omicron activity suggests the real-world benefit of mask-wearing in isolation is likely to be modest, according to new research being presented at this year’s ECCMID.

Researchers reveal why viruses like SARS-CoV-2 can reinfect hosts and evade immune response
Using a tool called VirScan, Brigham investigators found that people produced shared antibody responses to certain regions of the virus, likely leading to selective pressure and new variants that can repeatedly escape detection by prior immunity.

Microbes that “eat together” may benefit from a shared immunological memory
A new study examines viruses that infect microbes in the deep sea and finds evidence that viruses interact with a far more diverse set of hosts than was previously thought.

Gene scissors used successfully in the laboratory against HIV-related virus
Researchers have provided initial proof of concept for a potential therapeutic approach targeting HTLV-1, a retrovirus that triggers aggressive forms of leukemia or an incurable spinal cord disease that leads to paralysis.

Mosquito saliva can weaken body’s defenses against deadly dengue viruses
The saliva of mosquitoes infected with dengue viruses contains a substance that thwarts the human immune system and makes it easier for people to become infected with these potentially deadly viruses, new research reveals.

Human case of tick-borne encephalitis virus acquired in the UK for first time
The first confirmed domestically-acquired case of tick-borne encephalitis virus (TBEV) has been identified in a man who was bitten by ticks in Yorkshire, and another probable human case has been detected in the Loch Earn area of Scotland.

Team designs molecule to disrupt SARS-CoV-2 infection mechanism
A team of scientists led by the Department of Energy’s Oak Ridge National Laboratory has designed a molecule that disrupts the infection mechanism of the SARS-CoV-2 coronavirus and could be used to develop new treatments for COVID-19 and other viral diseases.

Flu can trigger a heart attack, Dutch study suggests
Individuals who are diagnosed with flu are six times more likely to have a heart attack in the week after they test positive for the virus than they are in the year before or afterwards, a Dutch study being presented at this year’s ECCMID 2023 has found.

Antibiotics do not reduce risk of dying in adults hospitalised with common respiratory infections, suggests study
Most patients admitted to hospital with acute viral respiratory infections are given antibiotics. Now new research to be presented at this year’s ECCMID in Copenhagen suggests that prescribing antibiotic therapy to adults hospitalised with common viral respiratory infections such as influenza is unlikely to save lives.

A water-dampened wipe removes Covid virus from indoor surfaces
Wiping indoor surfaces with a water-dampened wipe removes greater than 80% of Covid virus, yet pre-wetting the surface with water or detergent doesn’t make much difference, a new EPA study finds.
