Researchers examine the evolutionary race between SARS-CoV-2 and human defenses

Analysis indicated the number of mutations in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding domain (RBD) doubles every 72 days. As the coronavirus disease 2019 (COVID-19) pandemic continues infecting more people, SARS-CoV-2 is also evolving. Several new variants of the virus have now been discovered, some more infectious than the original strains. This

What are Coronaviruses?

Skip to: What are coronaviruses? Why are coronaviruses dangerous? SARS-CoV-2 / COVID-19 SARS-CoV MERS-CoV The rapid spread of the virus that causes the coronavirus disease (COVID-19) has sparked alarm across the globe. The World Health Organization (WHO) has declared the condition a global pandemic, with many countries grappling with the rise of infections. The disease

Trump issues executive order to improve flu vaccine

President Donald Trump signed an executive order aimed at developing better flu vaccines to defend Americans against both seasonal influenza and the possibility of a future pandemic outbreak. Interested in Flu Season? Seasonal flu “kills tens of thousands of Americans each year,” Alex Azar, secretary of Health and Human Services, said in a statement. A

Mumps study shows immunity gaps among vaccinated people: College-aged study participants received MMR as children

Immunity against mumps virus appears insufficient in a fraction of college-aged people who were vaccinated in childhood, research from Emory Vaccine Center and the Centers for Disease Control and Prevention indicates. The findings highlight the need to better understand the immune response to mumps and mumps vaccines. In the last 15 years, several mumps outbreaks

Lung neuropeptide exacerbates lethal influenza virus infection: Researchers find that neuropeptide Y (NPY) makes influenza worse when produced by lung immune cells

Severe influenza virus infection is characterized by a strong inflammatory response and profuse viral replication in lungs. These viruses, such as the notorious avian flu, have a high rate of death and to date there are no effective treatments. A research group led by National Institutes of Biomedical Innovation, Health and Nutrition (NIBIOHN) and Osaka

Near-infrared spectroscopy could improve flu vaccine manufacturing

Recent research from North Carolina State University outlines how near-infrared (NIR) spectroscopy could be used to make cell-culture-based flu vaccine manufacturing faster and more efficient. The researchers demonstrated the use of a NIR probe to measure the concentration of influenza virus in cells being grown in a bioreactor. “The NIR technique is faster, more accurate

8 common myths about cold and flu debunked

Many people love autumn for the colorful foliage and pumpkin spice, but each year it ushers in another season that is more menacing: cold and flu season, that is. The two illnesses are often lumped together, but there are important distinctions. And when it comes to prevention and treatment, there are plenty of misconceptions that

Dogs can be a potential risk for future influenza pandemic

Dogs are a potential reservoir for a future influenza pandemic, according to a study published in the journal mBio. The study demonstrated that influenza virus can jump from pigs into canines and that influenza is becoming increasingly diverse in canines. “The majority of pandemics have been associated with pigs as an intermediate host between avian

Characteristics of microorganisms most likely to cause a global pandemic

Infectious disease preparedness work focuses predominantly on an historical list of pathogens derived from biological warfare agents, political considerations, and recent outbreaks. That fails to account for the most serious agents not currently known or without historical precedent, write scholars from the Johns Hopkins Center for Health Security in a new report on the traits

Clues for improved influenza vaccine design

Influenza vaccines that better target the influenza surface protein called neuraminidase (NA) could offer broad protection against various influenza virus strains and lessen the severity of illness, according to new research published in Cell. Current seasonal influenza vaccines mainly target a different, more abundant influenza surface protein called hemagglutinin (HA). However, because influenza vaccines offer
