Influenza (the flu) is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. The best way to prevent the flu is by getting a flu vaccination each year. Every year in the United States, on average 5% to 20% of the population gets the flu; more than 200,000 people are hospitalized from flu complications, and; about 36,000 people die from flu-related causes. Some people, such as older people, young children, and people with certain health conditions, are at high risk for serious flu complications.
When obesity occurs, a person's own fat cells can set off a complex inflammatory chain reaction that can further disrupt metabolism and weaken immune response--potentially placing people at higher risk of poor outcomes from a variety of diseases and infections, including COVID-19.
A team of scientists from Stanford University is working with researchers at the Molecular Foundry, a nanoscience user facility located at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), to develop a gene-targeting, antiviral agent against COVID-19.
Scientists have discovered certain segments of the genetic codes of the SARS and COVID-19 viruses that may support the lifecycle of the viruses.
New research from University of Alberta microbiologists has shed new light on how the respiratory syncytial virus (RSV)--one of the most common viral infections--breaks into our cells to cause infection.
A new study from researchers at The University of Texas at Austin has found that some antivirals are useful for more than helping sick people get better -- they also can prevent thousands of deaths and hundreds of thousands of virus cases if used in the early stages of infection.
EKF Diagnostics, the global in vitro diagnostics company, announces it has secured new contracts for the manufacture and supply of a novel, patented sample collection device which allows COVID-19 samples to be rapidly inactivated in the collection tube, avoiding contamination and preserving RNA without need for refrigeration.
Researchers report that smoking increases the gene expression of ACE2, the protein that binds SARS-CoV-2, which may promote COVID-19 infection.
A group of tiny RNA that should attack the virus causing COVID-19 when it tries to infect the body are diminished with age and chronic health problems, a decrease that likely helps explain why older individuals and those with preexisting medical conditions are vulnerable populations, investigators report.
With a discovery that could rewrite the immunology textbooks, an international group of scientists, including the teams of Bart Lambrecht, Martin Guilliams, Hamida Hammad, and Charlotte Scott (all from the VIB-UGent Center for Inflammation Research) identified a new type of antigen-presenting immune cell.
When a person contracts a respiratory viral infection like COVID-19 or influenza, the immune system responds in a myriad of ways to eliminate the virus.
The hunt for an effective treatment for COVID-19 has led one team of researchers to find an improbable ally for their work: a llama named Winter.
Viruses are responsible for causing many different diseases, with the present coronavirus pandemic being one such example. Hence, these infectious agents are part of the human experience all through their lives.
A study has been launched to understand how the body's immune system responds to COVID-19, including if and when a person could be re-infected with the virus.
Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of death around the world. Now, two internationally acclaimed stem cell experts have discovered a large number of abnormal stem cells found in the lungs of COPD patients.
