Influenza

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.

Types of Influenza

Influenza is caused by three types of RNA viruses called influenza types A, B and C (considered different genera), which all belong to the family Orthomyxoviridae. The disease, colloquially called "flu" in humans, is generally caused by the viruses A and B, which are transmitted by aerosols from infected individuals or via close contact with infected animals.

New SARS-CoV-2 variant emerges in the U.S.

Even as the rollout of vaccines all over the world brings a glimmer of hope that the current coronavirus disease 2019 (COVID-19) pandemic may end in the near future, new variants continue to emerge, some with the potential to escape vaccine-induced or therapeutic antibodies. Now, a new preprint research paper published on the bioRxiv server describes a new American variant that may have become the dominant strain in the USA.

Research suggests St. John's Wort and Echinacea could protect against COVID-19

Researchers in Saudi Arabia have conducted a study demonstrating the antiviral effects of two medicinal herbs against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Image-based deep learning haplotype-guided study maps the global adaptation of SARS-CoV-2

A new study used deep learning with image recognition technology to trace the emergence of variants with increased viral fitness. Higher fitness leads to rapid expansion of these lineages in the areas where they are introduced. This type of study could facilitate the development of more effective antibodies and vaccines to help contain the pandemic.

New N501 SARS-CoV-2 mutation may have been circulating in Italy since August 2020

A recent study shows that mutated SARS-CoV-2 strains with a substitution at position 501 might have circulated unnoticed even before the end of September 2020, when the rapid emergence of B.1.1.7 lineage (carrying the N501Y mutation) was initially reported.

Study summarizes effectiveness of cloth masks in protecting clinicians from COVID-19

A rapid, evidence-based review summarizes the effectiveness of cloth masks in protecting health care clinicians from respiratory viral infections, such as COVID-19. Nine studies were included in the review, and all but one were conducted prior to the COVID-19 pandemic.

SARS-CoV-2 may join the ranks of mild cold-causing coronaviruses

What is the endgame for SARS-CoV-2, the virus that is causing worldwide devastation? If it becomes endemic -- circulating in the general population -- and most people are exposed in childhood, SARS-CoV-2 may join the ranks of mild cold-causing coronaviruses that currently circulate in humans, according to a model developed by Emory and Penn State scientists.

Biologists reveal unusual structure of coronavirus protein linked to immune evasion

A team of HIV researchers, cellular biologists, and biophysicists who banded together to support COVID-19 science determined the atomic structure of a coronavirus protein thought to help the pathogen evade and dampen response from human immune cells.

Study shows COVID-19 pneumonia is different from typical pneumonia

Bacteria or viruses like influenza that cause pneumonia can spread across large regions of the lung over the course of hours. In the modern intensive care unit, these bacteria or viruses are usually controlled either by antibiotics or by the body's immune system within the first few days of the illness.
