On the Origin of New Diseases

Microbes have been around since creation, and are beneficial to many living things. After the fall of man, everything changed. Mutations, one of the heroes of fish-to-fool evolution, helped cause some of the changes in those microbes.

The world is not at equilibrium. While we have "new" diseases that are actually variants of those previously existing, there are also some that are genuinely new to us. Did evolution bring them about? Not at all. The whole thing is quite complicated.

Viruses, bacteria, other microorganisms are usually beneficial. Something changed after the creation. Explaining new diseases like COVID-19 is very complicated.
Our Creator designed things to work together in their proper places, but microbes can be displaced from animals to humans. There is a One Health concept where microorganisms and such live in human and animal hosts as well as reservoirs. Changes cause things to jump to other organisms.

At this writing, there is evidence that the SARS-CoV-2 virus is connected to a lab in Wuhan (a discussion that is being hindered), but don't completely disregard the part of that origin story regarding bats. Three out of four new infectious diseases that people have begin in animals. Those microbes tend to be fine when living in various critters, but when they are transmitted to humans, things can get serious mighty quick.

The following article is rather technical and is provided for people who have knowledge and interest in biological sciences.

New and reemerging diseases are terrifying and concerning problems. Not only do they carry a financial and emotional toll, but they account for significant numbers of death. Emerging diseases are usually zoonotic and highly virulent in nature. These are pathogenic and parasitic diseases of high consequence and impact. Why would a good Creator allow these new diseases? Why do new diseases keep popping up? Mutation and displacement of original types of microbes account for many new diseases; however, the answer is more complex than just these two factors. . . . Some goals of this article are to explain the concepts of displacement, mutation, and “One Health” while solving the riddle of pandemics, plagues, and pestilences. We will examine the relationship between humans, microbes, and animals and explore the principles of new and reemerging diseases by giving a few examples.
