Certainly something causes these infections, and triggers the resulting stresses on the body. Are we just discussing the generic name of these entities, or is there a deeper issue here.
badecker read on some stupid site that we are in the 18th century and there is no way to identify anything smaller than the human eyesight. and the only chemical reactions that are possible are using herbs
he hassnt wised up that we are in the 2st century
he kinda knows, but then lets the dumb part of his brain forget again, that they can actually identify not only visually via a microscope, but also through chemical reaction, extraction, sequencing and comparison. and work out whats similar and whats different
they have the rna sequence of corona viruses and they know it differs to ebola or bacteria
they can see that the same sequence is found in people that are sick with a certain symptomology but not find it in healthy people
they can see that the pathogen they find in ebola symptomology differs from those with covid symptomology
they have extracted purified and then put it into test specimens and those test specimens also got sick with the particular symptomology. so they do know what they are looking at is the cause of the sickness
then looking at it and looking at the rna sequence and other enzyme studies they know its not an exosome
heck exosomes dont even do the same job that a virus does
people can keep teaching badecker this stuff.. but he will always forget as soon as he clicks the bookmark to his hotlist of conspiracy sites. because he is an idiot that way.
