Emerging infections pose a threat to public health from "summary" of An Unnatural History of Emerging Infections by Ron Barrett,George Armelagos (the late)
Emerging infections, those previously unknown or known but spreading to new geographic areas or populations, have become a significant concern in the realm of public health. These infections have the potential to rapidly spread and cause widespread illness and death among populations that lack immunity to the new pathogen. The emergence of new infections can be attributed to a variety of factors, including changes in land use, climate change, global travel, and the encroachment of humans into previously untouched ecosystems. The threat posed by emerging infections is exacerbated by the interconnected nature of our modern world. With the ease and speed of travel, an infectious agent can quickly move from one part of the globe to another, making containment and control efforts more challenging. Additionally, the global food supply chain can serve as a vector for the spread of infectious diseases, further increasing the risk of a widespread outbreak. Furthermore, the rise of antimicrobial resistance has further complicated the issue of emerging infections. As pathogens evolve to become resistant to the drugs used to treat them, the effectiveness of treatment options diminishes, leaving healthcare providers with limited options to combat the spread of these infections. This can lead to longer and more severe illness, increased healthcare costs, and a higher mortality rate among infected individuals.- The threat of emerging infections to public health cannot be underestimated. The potential for these infections to rapidly spread and cause widespread illness and death highlights the importance of vigilant surveillance, effective response strategies, and ongoing research into the prevention and control of these diseases. Failure to address the issue of emerging infections could have dire consequences for global public health.
