N and S sgmRNA molecules number per cell according to the viral RNA content group.

Viral RNA content group	genomic ORF1ab (copies/ng RNA*)	N sgmRNA (copies/ng RNA*)	S sgmRNA (copies/ng RNA*)	N sgmRNA copies/cell	S sgmRNA copies/cell
High	467,936	86,334	8,702	1,727	174
Middle	8,864	1,251	87	25	1.7
Low	74	16	1	0.3	0.02

^*Values are reported as the mean of copies/ng RNA values.
