What is the significance of emerging and re-emerging infections?

Emerging and re-emerging infections are significant because they can pose serious public health threats, often outpacing existing medical responses and control measures. They can arise due to factors such as globalization, environmental changes, and antibiotic resistance, leading to increased morbidity and mortality. Understanding these infections is crucial for developing effective surveillance, prevention, and treatment strategies, ultimately safeguarding global health. Additionally, they highlight the need for continual research and preparedness in the face of evolving pathogens.
