“For example, diet-induced oxidative stress, micronutrient status, and aging can influence influenza virus virulence. The authors of the study serially infected lean and obese mice with the influenza virus to replicate the spread of influenza within the real-world setting.”

“Interferons are proteins produced by the body's cells as a defensive response to viruses. The ensuing inflammation prevents the virus from invading and replicating in the cancer cell, undermining the pathogen's efficacy.”

“These cells make antibodies, which in turn neutralize the viruses, rendering them harmless. Some B cells become memory B cells, which can remain in the body for a long time, even after the virus is cleared, to efficiently recognize and destroy returning viruses.”

“Neurogenesis Whereas the early view of the mammalian central nervous system presumed that it was a static complex incapable of change, a growing body of evidence suggests that it retains its capacity for synaptic pruning – the process that eliminates extra neurons and synaptic connections and establishes new neural circuits to increase the efficiency of neuronal transmissions – throughout life.”

“Virologists consider this unlikely because it goes against typical viral behavior. As non-living entities, viruses rely on the survival of their host to propagate — if the host is killed too quickly, the virus will not have time to reproduce.”

“They cautioned that low sunlight exposure in many northern cities during the winter months may lengthen the 90 percent sterilization time. Further research is needed to understand why sunlight sterilization is more effective against the SARS-CoV-2 virus than originally estimated.”

“One of the pathological hallmarks of Alzheimer's disease is amyloid-beta plaque formation in the brain. Findings from a new study suggest that herpes simplex virus I infection contributes to the formation of amyloid-beta plaques.”

“The authors of the study used atomic force microscopy to observe how well the virus-like particles withstood environmental changes. They applied the virus-like particles to a glass surface and then exposed them to different temperatures (ranging from 71° F to 93° F) in humid and dry conditions.”

“People who are infected with a virus commonly report having aches and pains. Most people who are infected with SARS-CoV-2, the virus that causes COVID-19, exhibit symptoms such as fever, cough, and difficulty breathing, but not pain.”

“On December 18, 2020, the Food and Drug Administration granted emergency use authorization for the Moderna mRNA vaccine against SARS-CoV-2, the virus that causes COVID-19. In recent weeks, however, variants of the SARS-CoV-2 virus have emerged, raising questions about the vaccine's efficacy.”
