What a difference an edition makes. In the preface to the previous edition of Fundamentals of Microbiology, I remarked that “Today … despite extraordinary advances to eliminate or lessen the development and spread of infectious disease, their appearance continues —and indeed, it is inevitable.” I went on to say that “more than 60% percent of new human infections originate in, or are transmitted by, wild animals, [including] AIDS (apes and monkeys to humans), SARS and Ebola (bats [to other animals] to humans), and Zika (monkeys to mosquitoes to humans). Consequently … unknown infectious microbes in wild animals will ‘jump’ to humans as these interacting species make contact … adding to these factors is the globalized world we live in today. Airline travel makes an infectious disease outbreak in one corner of the world only a day’s plane ride from almost any other destination on the globe. Accordingly, infectious diseases can ‘pop up’ from seemingly nowhere.” Many disease experts around the world for decades have said that it is not if a disease pandemic will happen, but rather when it will happen. And, so it has in the form of coronavirus disease 2019 (COVID-19). I went on to echo the thoughts of numerous health experts that “Each new emerging disease brings unique challenges, forcing the medical community to continually adapt to these ever-shifting threats. The battle against emerging infectious diseases is a continual process in trying to get ahead and stay ahead of the next infectious agent before it can explode on the world scene.” Unfortunately, that next infectious agent has exploded on the world in the form of the SARS-CoV-2 virus, the infectious agent for COVID-19. It certainly has brought many new challenges to every aspect of work, school, economics, health care, and societal behaviors (social distancing, wearing masks, etc.). All of us have and will continue to be impacted in every aspect of our lives by this disease.
