A nasal COVID-19 vaccine blocks transmission of the virus, according to an animal study. The findings suggest that vaccines delivered directly to the nose or mouth could play a critical role in containing the spread of respiratory infections. The lightning-fast development of COVID-19 vaccines just months after the virus appeared was a triumph of modern

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. The findings provide clues as to why some viruses have greater 'pandemic potential' than others and how researchers

Researchers have identified a potential treatment for the respiratory symptoms of long COVID after discovering an unknown cause of the condition inside the lungs.

The

SARS-CoV-2, the virus responsible for COVID-19, is widespread among wildlife species, according to new research. The virus was detected in six common backyard species, and antibodies indicating prior exposure to the virus were found in five species, with rates of exposure ranging from 40 to 60 percent depending on the species. SARS-CoV-2, the virus responsible

The COVID-19 pandemic significantly widened existing economic and health disparities between wealthy and low-income countries and slowed progress toward health-related Sustainable Development Goals (SDGs), according to a new study.

Whether or not a person becomes seriously ill with COVID-19 depends, among other things, on genetic factors. With this in mind, researchers investigated a particularly large group of affected individuals. They confirmed the central and already known role of the TLR7 gene in severe courses of the disease in men, but were also able to

Rates of subsequent myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) following an acute illness were roughly the same between people whose acute illness was due to COVID-19 and those who did not have COVID-19, a new study finds. A new study led by UCLA finds that rates of subsequent myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) following an acute

The risk of long COVID has declined over the course of the pandemic, although it remains a persistent threat. Researchers identified vaccination as a primary factor in reducing the risk of long COVID. The risk of developing long COVID has decreased significantly over the course of the COVID-19 pandemic, according to an analysis of data

Building upon groundbreaking research demonstrating how the SARS-CoV-2 virus disrupts mitochondrial function in multiple organs, researchers demonstrated that mitochondrially-targeted antioxidants could reduce the effects of the virus while avoiding viral gene mutation resistance, a strategy that may be useful for treating other viruses.

American diets may have gotten healthier and more diverse in the months following the start of the COVID-19 pandemic, according to a new study. American diets may have gotten healthier and more diverse in the months following the start of the COVID-19 pandemic, according to a new study led by Penn State researchers. The study

Researchers have developed a bioelectric device that can detect and classify new variants of coronavirus to identify those that are most harmful. It has the potential to do the same with other viruses, as well. Cornell University researchers have developed a bioelectric device that can detect and classify new variants of coronavirus to identify those

Research finds that booster doses of bivalent vaccines given every three to six months helps maintain a person's ability to neutralize multiple SARS-CoV-2 strains, including XBB.1.5 People who have received solid organ transplants and take immunosuppressant medications to prevent rejection are among those most susceptible to the damaging effects of COVID-19, including breakthrough infections, severe
