Fiebig stage, transmission route, days since infection, and number of T/F viruses of heterogeneously infected individuals

Subject	Fiebig stage	Transmission route	Days from infection (95% CI)	No. of T/F viruses
CH0010	I/II	Heterosexual	9 (7, 11)	3	6
CH0078	I/II	Heterosexual	11 (7, 14)	2	2
CH0200	I/II	Heterosexual	15 (13, 17)	3	5
CH0047	III	Heterosexual	25 (21, 29)	2	2
CH0228	III	Heterosexual	24 (21, 28)	2	3
CH0275	I/II	Heterosexual	12 (8, 16)	1	2
CH0654	I/II	MSM	15 (13, 17)	9	8
CH1244	IV	Heterosexual	12 (11, 13)	NA	2
CH1754	III	Heterosexual	14 (12, 15)	6	7

Days from infection were calculated using previously published methods³³. These methods generally strongly correlate with Fiebig stage, though occasional deviations still happen, especially when under strong selection. In our present dataset, CH1244 is one such exception, with a Fiebig stage IV yet diversity that would be expected—under a model of random accumulation of mutation—to be roughly 2 weeks into the infection
