Final answer:
New viruses produced in bacteria are important for their evolution and potential to infect new hosts. Viral reproduction can lead to changes in newly produced viruses, allowing them to interact with different host receptors and spread quickly. Monitoring newly appearing viruses helps reduce the risk of global viral epidemics.
Step-by-step explanation:
When new viruses are produced in bacteria, it is important because it allows for the viruses to evolve and potentially infect new hosts. Viral reproduction can lead to errors and changes in the newly produced viruses, which may result in new binding properties that can interact with different host receptors. This enables viruses to jump to new hosts and spread quickly. By monitoring newly appearing viruses, scientists can reduce the likelihood of global viral epidemics.
