Is CoV-2 confirmed as the cause of this pandemic?

As you know, COVID-19 (aka SARS CoV-2) is said to be affecting senior citizens (like me) more than any other group. But is that really true? Or, is SARS CoV-2 a follow-on infection after pneumonia or other disease which weakened the immune system? 

As far as I can find, neither Koch’s postulates nor Rivers postulates (1), the standards for confirmation of cause (etiology) of infectious diseases, has been completed or published for SARS CoV-2. If you have done this virology, or if you can provide a reference to such a report, then please you would be helping us all by letting us know where it is published.

My literature search found no confirmation Koch’s or Rivers’ postulates has been fulfilled for SARS CoV-2, which is commonly called Covid-19, and merely associated with the deaths and disease in this so-called pandemic. A PCR test confirms that a specific sequence is found in the patient sample. An antibody test confirms that the patient has antibodies for a given pathogen. But, an association or correlation of a sequence or antibody with a disease is not equivalent and does not prove cause.

Do your own literature search. The scientists and papers usually mention justification or reason that Koch’s or Rivers’ postulates have not been fulfilled for CoV-2, for example the absence of a validated animal model is mentioned as well as the difficulties with animal models and cell culture media. (3)

SARS CoV-1 was confirmed following Koch’s postulates in 2003 by Dutch scientists. (2) But sequence homology between CoV-1 and CoV-2 has been reported at about 79%, while for example, homology between bat and CoV-2 is about 96%.  

Without confirmation of cause following Koch’s or Rivers’ postulates, the world is probably doing extensive and expensive testing for sequence and antibodies and designing vaccines for exosomes or apoptotic bodies.

Time for some due diligence please.
