A new study from Columbia researchers, in collaboration with scientists at the University of Hong Kong, adds more evidence that the omicron variant can evade the immune protection conferred by vaccines and natural infection and suggests the need for new... Continue Reading →
New evidence shows that patients with Long COVID syndrome continue to have higher measures of blood clotting, which may help explain their persistent symptoms, such as reduced physical fitness and fatigue. The study, led by researchers from RCSI University of... Continue Reading →
As the COVID-19 pandemic has progressed, it has become clear that many survivors -- even those who had mild cases -- continue to manage a variety of health problems long after the initial infection should have resolved. In what is... Continue Reading →
Scientists are still solving the many puzzling aspects of how the novel coronavirus attacks the lungs and other parts of the body. One of the biggest and most life-threatening mysteries is how the virus causes "silent hypoxia," a condition when... Continue Reading →
A new study of the U.K. and South Africa variants of SARS-CoV-2 predicts that current vaccines and certain monoclonal antibodies may be less effective at neutralizing these variants and that the new variants raise the specter that reinfections could be... Continue Reading →
Researchers using MRI have found significant abnormalities in the eyes of some people with severe COVID-19, according to a study published in the journal Radiology. The study results support the need for eye screening in these patients to provide appropriate treatment... Continue Reading →
Georgia State University biology researchers have found that infecting the nasal passages of mice with the virus that causes COVID-19 led to a rapid, escalating attack on the brain that triggered severe illness, even after the lungs were successfully clearing themselves of... Continue Reading →
To understand how COVID-19 vaccines work, it helps to first look at how our bodies fight illness. When germs, such as the virus that causes COVID-19, invade our bodies, they attack and multiply. This invasion, called an infection, is what... Continue Reading →
