As a local epidemic I consider in this context e.g.
Ebola in opposition to
influenza. Because pathogenic germs are animated by psychons and the number of such psychons is limited, the number of germs is also limited.
From this point of view, instead of killing all animals having come into contact with a pathogen, as it is regularly done in our days, in the long run it would make more sense to infect as many animals as possible, and to apply the efficient principle of natural selection. This leads on the one side to farm animals with stronger immunity and on the other side to less virulent viruses, because those viral strains tending not to kill their hosts can survive whereas those related strains killing their hosts perish together with their hosts.
Even after
immunity, harmlessly small amounts of pathogens can survive. This has the advantage that also the corresponding antibodies do not become extinct in the host organism.
The immune systems, in the same way as many other properties of the animals of factory farming are degenerating. Over generations, serious negative effects can emerge.
In any case, we must take into consideration that pathogenic germs (in the same way as the many non-pathogenic germs) which use us or other living beings as hosts have emerged on earth and co-evolved with their hosts over millions of years.
The increase in world population has a positive effect on our health insofar as the numbers of all the germs using humans as hosts are limited by corresponding psychon numbers. So the more humans are alive at the same time, the lower are the proportions of such germs per human.
Big epidemics have always also been the result of weakened immunity due to bad living conditions, e.g. at the end of the first world war (the 1918 flu pandemic). In such cases, in which a virulent pathogen meets a weakened population, the rapid dying of the ones can lead to a further increase in the virus load of the others, because the virus psychons having lost their habitat in the deceased can become active in the infected surviving. Virus particles without corresponding psychons are as harmless as a destroyer without crew and energy.
In any case, it does not serve the interest of the germs that they sometimes kill their hosts. So instead of trying to exterminate such pathogens, we should rather try to transform them into harmless symbionts.
As long as there are enough birds and related species as hosts for the
avian influenza virus, there is absolutely no risk that this virus suddenly could start using humans as hosts. Why should it? The corresponding psychons have co-evolved with birds and are optimally adapted to birds. Without necessity psychons do not like to change their environment, in a similar way as educated human souls do not like the change their world view.
