Evolution of Disease Pathogens

Pathogens, like bacteria and viruses, evolve over time to adapt to their environments, including their human hosts. This evolution occurs through mutations and natural selection, allowing some pathogens to become more resistant to treatments, like antibiotics or vaccines. As they spread, these adapted strains can lead to outbreaks or more severe diseases. Human behavior, such as overusing medications or lack of vaccination, can accelerate this process. Understanding this evolution helps in developing effective strategies to combat diseases and highlights the importance of responsible health practices to minimize the emergence of resistant pathogens.
