Explore the dynamics of variant evolution in a lecture from the "Emerging Infectious Diseases: Ecology and Evolution" program. Delve into the question of whether the evolution of variants is mutation-limited or selection-limited with Dr. Milind Watve. Gain insights into the complex interplay between mutation rates and selective pressures in shaping the genetic diversity of pathogens. Examine how these factors influence the emergence and spread of new variants in infectious diseases. Learn about the implications of this evolutionary process for disease ecology, public health, and the development of effective intervention strategies. Enhance your understanding of the fundamental principles driving pathogen evolution and their relevance to current global health challenges.
