If the virus has an HIV type”spike” to it I get concerned that it might also have HIV type cronicity and stay latent and contagious the same way HIV, herpes or hepatitis viruses do.
Hence if such is the case, some folks may never show negative tests even though they are “stable”, they may continue to be latent sources of contagion.
if you are in the science field I posted a thread today with a crazy amount of scientific information in it with a lot of bio data
As I read it, the Chinese-made chimera graft to the spike was to enhance the ACE2 affinity. But maybe your hypothesis will bear out too.
