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.
An ancient gene mutation among First Nations inhabitants of Oceania may make them more susceptible to infectious diseases like influenza, according to a new study by scientists at the University of Colorado Anschutz Medical Campus.
According to a recent study published in Nature, mice and ferrets infected in a high-containment laboratory setting died from a highly pathogenic avian influenza (HPAI) H5N1 virus that was isolated from the eye of a farm worker who contracted the virus from contact with dairy cows.
Human bodies are attacked every single second of every day. The invading agents include bacteria, viruses, parasites, and toxins both living and non-living things that could impair how well bodies work.
Researchers from the University of Georgia discovered in a recent study supported by the National Institutes of Health that the effectiveness of upcoming influenza vaccinations is significantly influenced by the body's innate immunity from prior flu episodes.
In the UK’s largest study to date, novel steps have been taken to gain a better understanding of the immediate and long-term effects of COVID-19 on the brain.
Investigators involved in a multicenter study co-led by Cedars-Sinai discovered a pathway by which immune cells prevent the lungs' protective barrier from healing after viral infections like COVID-19.
A recent study by the Cusack group clarifies how a crucial enzyme of the avian influenza virus can change, enabling the virus to spread to mammals.
A viral spillover of the highly pathogenic avian influenza virus belonging to the hemagglutinin 5 neuraminidase 1 (H5N1) 2.3.4.4b clade among herds of dairy cattle.
Scientists at La Jolla Institute for Immunology (LJI) have published the first-ever, in-depth analysis of immune cell memory in the upper airways of adult volunteers. Among these immune cells, the researcher spotted "tissue resident" memory cells, which stand ready to defend the airway from SARS-CoV-2 and other respiratory diseases.
A new study reveals evidence that avian influenza has spilled over from birds to dairy cattle across several U.S. states, resulting in mammal-to-mammal transmission between cows and from cows to cats and a raccoon.
The majority of influenza viruses enter animal or human cells through particular surface-based pathways. It has recently been found by researchers at the University of Zurich that some influenza viruses, both human and avian, can also enter cells through a second entry point that involves an immune system protein complex.
Researchers recently discovered that auto-antibodies against their type 1 interferons, crucial immunological signaling proteins, were present in some COVID-19 patients.
The highly virulent H5N1 avian influenza was initially found in dairy cattle in the United States in March, and by May, outbreaks had been reported from nine states. The research was published in the journal Nature Communications.
Scientists at UC Riverside have demonstrated a new, RNA-based vaccine strategy that is effective against any strain of a virus and can be used safely even by babies or the immunocompromised.
By focusing on a poxvirus protein, a team led by UT Southwestern Medical Center scientists has discovered an antiviral immune pathway that broadly fights a wide variety of viruses.
The highly pathogenic avian influenza virus H5N1 has adapted to spread between birds and marine mammals, posing an immediate threat to wildlife conservation, according to a study from the University of California, Davis, and the National Institute of Agricultural Technology (INTA) in Argentina.
Using a virus-like delivery particle made from DNA, researchers from MIT and the Ragon Institute of MGH, MIT, and Harvard have created a vaccine that can induce a strong antibody response against SARS-CoV-2.
The composition of microbiota found in the gut influences how susceptible mice are to respiratory virus infections and the severity of these infections, according to researchers from the Center for Translational Antiviral Research in the Institute for Biomedical Sciences at Georgia State University.
Cold, flu and COVID-19 season brings that now-familiar ritual: swab, wait, look at the result. But what if, instead of taking 15 minutes or more, a test could quickly determine whether you have COVID-19 with a glowing chemical?
The body's immune response to Epstein-Barr virus (EBV) may play a role in causing damage in people with multiple sclerosis, according to a new study led by UTHealth Houston.
