Table 2. Correlation between Viral Type and Previous Herpes Simplex Virus Type 1 Antibody Status and Subsequent Frequency of Asymptomatic Reactivation of Herpes Simplex Virus from the Genitourinary Tract after First-Episode Genital Herpes^*.

Asymptomatic Shedding	Primary Type 1	Primary Type 2	Nonprimary Initial Type 2
	n/N (%)
Days of asymptomatic cervical viral shedding†	2/328 (0.6)	54/1749 (3.1)	6/228 (2.6)
Days of asymptomatic vulvar viral shedding‡	2/308 (0.6)	36/1540 (2.3)	2/236 (0.8)
Asymptomatic shedding at both cervix and vulva at same visit§	0/303 (0)	16/1483 (1.1)	1/218 (0.5)
Days with asymptomatic shedding from any genital site†	4/335 (1.2)	78/1820 (4.3)	8/246 (3.3)

^*Analyses confined to “routine” visits in the first year after acquisition of infection. HSV = herpes simplex virus.

^†P < 0.05 for comparison between primary HSV-2 and primary HSV-1 or nonprimary HSV-2 and primary HSV-1.

^‡P < 0.05 for comparison between patients with primary HSV-2 and other patients with initial episodes of genital herpes.

^§Among days when both sites were cultured.
