The relationship between viral mutations and disease emergence is significant as mutations can lead to the development of new viral strains. These alterations may enhance the virus’s ability to infect hosts, evade the immune system, or increase transmission rates. Such mutations can lead to outbreaks of diseases, especially in the case of viruses like influenza and SARS-CoV-2. Understanding these relationships is crucial for public health, informing vaccine development and strategies to manage potential epidemics.
