Yeah.. and what i heard earlier was the covid19 mutates very slowly.. now suddenly thy say thre r 30 mutations.. btw as i remember RNA viruses usually mutates and become less agressive ryt.. rarely thy become agressive.. isnt it??
This is exactly what happened with SARS. A 29 nucleotide deletion within ORF8 occurred in all strains involved in the middle and late phases. Subtotal or total deletions of up to 415 nts occurred within and around the ORF8 region in the very late phase of the epidemic.
This really made is more aggresive but also made it UNABLE to infect the humans
That led to the downfall of SARS.
