Estimation of the fraction of HIV-1-infected CD4⁺ T cells involved in active virus production in tonsillar tissue

Patient no.	Cells containing infectious provirus*	p24+ cells†	Percent p24+ infected cells‡
1	50	<3	<6
2	250	7	2.8
4	4,125	113	2.7
10	12,000	240	2.0
12	12,000	347	2.9

^*Number of cells containing infectious provirus copies/10⁶ CD4 cells. 

^†Number of p24⁺ cells/10⁶ CD4 cells. Values represent mean of two counts from independent slides. 

^‡Estimation of the fraction (in percent) of provirus-containing CD4 cells in tonsils staining positive for p24 antigen.
