Are new variants of COVID-19 possible?
New variants of the virus are expected to occur. Taking steps to reduce the spread of infection, including getting a COVID-19 vaccine, are the best way to slow the emergence of new variants.
What is known about the COVID-19 Omicron variant?
Preliminary evidence suggests an increased risk of reinfection with this variant, as compared to other” variants of concern, the organization said in a statement Friday. “(This) variant has been detected at faster rates than previous surges in infection, suggesting that this variant may have a growth advantage.”
Is the Mu variant of COVID-19 a ‘variant of interest’?
Although the World Health Organization continues to classify Mu as a ‘variant of interest’ globally, the CDC lists Mu simply as a ‘variant being monitored. ‘ The CDC counts 10 variants in the variant being monitored group, including three once considered variants of concern: the Alpha, Beta, and Gamma
How does the Omicron variant of COVID-19 differ from the Delta variant?
Scientists from South Africa also believe omicron may lead to more cases of reinfection in people who’ve already had COVID-19. Omicron has more mutations on its spike protein than the delta variant does, but whether or not that means anything remains to be seen.
Can computational biology predict the evolution of viruses?
Computational biologists used an algorithm meant to model human language to instead predict how viruses could evolve to evade the immune system. Save this story for later. Viruses lead a rather repetitive existence.
What happens if a virus has a mutation?
Most mutations are harmful to the virus and prevent it from replicating. For instance, mutations in the genetic code might lead to misformed proteins that cannot assemble a protein shell around the new viral DNA or RNA.
Why is it important to study viral mutation rates?
Knowledge of the processes underlying viral mutation rates has implications for understanding and managing drug resistance, immune escape, vaccination, pathogenesis, and the emergence of new diseases. In clinics, the importance of viral mutation rates can be illustrated by the history of anti-HIV treatment.
Does ethanol increase the mutation rate of viruses?
Elevated levels of reactive oxygen species (ROS) and other cellular metabolites during viral infections can induce mutations in the host cell and in the virus. For instance, ethanol is likely to synergize with virus-induced oxidative stress to increase the mutation rate of HCV [ 21 ].
