2000 Years of Pandemics: Past, Present, and Future

It is noteworthy that the frequency of pandemics has increased over the past 2000 years. The authors identify three main drivers for the development of pandemics: transportation, human development, and changes in natural ecosystems. It is important to note that with the advent of the industrial age, the length of time it takes for a pandemic to develop has decreased. COVID-19 is certainly not the last pandemic we will face. Therefore, it is of paramount importance to learn from the past 2000 years to help educate general community and public health officials about pandemic risks and help governments prepare for the next pandemic.
