Can viruses mutate? Learn how viruses mutate due to antigenic shift and antigenic drift. See an antigenic shift vs drift comparison to see how the two differ. Related to this Question How are new viruses reproduced? How does a virus reproduce?
How do killer T-cells destroy viruses? How did HIV originate in humans? Is HIV a retrovirus? What is considered an undetectable viral load for HIV? What is an HIV provirus? How do cytotoxic T cells destroy pathogens? How does the immune system recognize a foreign cell?
In case you do not understand how a virus enters the host cells of your zygotes, and fetuses to permanently mutate our children, you need to take a course in virology to understand. When it disrupts the normal cell replication, the cells are changed permanently by mutations and only for th...
In a November, 2021 podcast interview, Gumrukcu claimed his pre-clinical-stage COVID-19 drug, which hasn’t even reached phase 1 trials, will both treat and prevent “any [current] variant or coronavirus strain” as well as “any variant the virus will mutate into” in the future. [1:...
the Norwalk virus. Based on genetic typing, we now know that there are at least 25 different strains of norovirus that affect humans. The RNA genome in noroviruses easily mutates to produce new norovirus types. The disease occurs worldwide with peak occurrence from about November until the ...
Virulence, or harm to host health, would increase with the cumulative viral load. If the virus mutates to a type that has a different antigen specificity, the immune reactions targeting the original type cannot suppress the mutant strain. Hence the mutant strain escapes immune surveillance. To ...
Well, then Virus particles or bacteria begin to wage war on the cell lining of your throat (if they entered through your mouth) and the mucus membranes often become inflamed and infected as those first casualties start to pile up. How does your body respond to this at...
Nevertheless, there is still considerable dispute as to the source of the virus; it could have been a Wuhan laboratory accident or animal exposure, but it seems unlikely that an intentional release occurred. Where does SARS-CoV-2 spread? When a new pathogenic appears, discovering the source is...
With such a novel technology, the chance of success is predicted to be no more than 2 percent, which is consistent with virologists’ warning that it’s theoretically unfeasible to make a vaccine for an RNA virus like SARS-CoV-2 because the virus mutates so fast. This is prec...
