Microbial world have dominated the earth for billions of years and gradually evolved to all forms of life as we know it, including plants, animals and us, humans. If the microbial longevity on earth is a book of 1000 pages, the human’s life history on earth is less than a line of it! Microbes of all types, from bacteria, to fungus, to parasites and viruses have survived through infestation of their hosts, including humans for billions of years, and we just came to know them not long ago, less than a couple of hundreds years ago. By learning about the hygiene, use of detergents, alcohol, other disinfectants, then anti-microbial agents such as antibiotics, and vaccines, we were able to fight some of these infections befalling on us. So until a little while ago, we thought that infections and infestations have faded out, at least from the developed lands and only remains to be a struggle in the developing nations due to poor hygiene and poverty. But the last few decades have opened our eyes very well that the “survival of the fittest” is still the rule and we are all at the mercy of the rulers of the earth, the microbes and we might be at the verge of extinction soon. Unfortunately our life history on earth could be a lot shorter than what we thought, not because of the greed of our war machines, or the anger of the sun or another extraterrestrial attack on our being, but by microbial invasions! While we thought of “evolution” as an upward phenomenon to create us, humans so to rule the world and destroy it, we well observed and understood that “evolution” is in every direction, and the “wisest” is not the “winner”, but the “strongest”.
Epidemics that have been a relatively rare incidents and exceptions in the past, have become the rule over the past couple of decades and have evolved to “Pandemics”! by our globalization, in fact we have helped the microbial world to get closer to all of us and we are not just sharing our gossips, greed, and ideas, but our germs. Through our infiltration to the nature and the wild, urbanization and destroying the environment, we have delineated the boundary between the civil and the wild life. As we will read in more detail in the following, more than %65 of our humans’ infections and the recent epidemics and pandemics are “Zoonotic” or originating from other animals, specially the wild life, into our very beings. It seems that the microbial invasions are all in full force and we are in full surrender, and we will fade out by acute attacks of epidemics and pandemics from outside, and at the same time, like Trojans invaded from within by the autoimmune disorders, cancers, degenerative, physical and mental disorders all caused by microbial invasions. If at the end anyone survives on earth, their genes have been mutated by the microbial attacks and we may not be humans after all as we know it today! Although these lines could be quite frightening and nightmarish, it is truly scientific and is known to microbiologists for a while. We may not have the solution to the survival yet, as the attacks are very serious and much sophisticated. But the first step is the knowledge of what is happening so to search for a collective solution and resistance altogether across the globe, that could never happen! In the following, after a brief review of the microbial invasions on humans throughout our short history, I will summarize an example of a few recent microbial invasions in the forms of epidemics and pandemics across the globe, while the list and detail of all could not be recorded here or perhaps anywhere else.
