2021 Ebola outbreak

It is important to know that Ebola clinical samples are routinely frozen before being sent to a diagnostic or research lab. Patient zero in this outbreak was a 51 year old nurse. It is in my opinion quite likely that she could have handled medical samples. What is highly suspicious about this outbreak is that the virus is basically identical to one found 6 years earlier, or that it stopped mutating for ~5 years. In my opinion, there is just no mechanism by which an RNA virus could remain infectious for 5 years if not frozen (such viruses normaly do not remain infectious for more than a few days). Alternatively, if the virus survived for example in an animal host, it should have collected 5 years worth of mutations. RNA dependent RNA polymerases always produce some errors, irrespective of the host. I have also approached 5 virologists with this issue, not one could explain how an RNA virus could remain infectious for that long if not frozen.
