Valacyclovir exhibits better oral absorption and higher, more prolonged serum concentrations than oral acyclovir. The efficacy of valacyclovir and acyclovir on genital herpes simplex virus (HSV) shedding was assessed in a double-blind, 3-period crossover trial. Sixty-nine immunocompetent participants with genital HSV-2 received oral valacyclovir, acyclovir, and matching placebo in random order for 7-week periods. Participants provided daily genital mucosal swabs for HSV detection by viral culture and polymerase chain reaction (PCR). HSV was detected at least once in 62 (90%) participants by culture and in 68 (98%) by PCR. During placebo, the total HSV shedding rate was 15.4% of days by culture (PCR, 40.2%); the subclinical shedding rate was 6.6% by culture (PCR, 27.1%). Both antivirals were associated with lower HSV shedding by culture (relative risk [RR], 0.03 [95% confidence interval , 0.01–0.07] for valacyclovir and RR, 0.05 [95% CI, 0.03–0.10] for acyclovir) and PCR (RR, 0.18 [95% CI, 0.12–0.26] for valacyclovir and RR, 0.20 [95% CI, 0.15–0.28] for acyclovir), compared with placebo. buy viagra overnight delivery Genital herpes is a chronic, life-long viral infection. Two types of HSV can cause genital herpes: HSV-1 and HSV-2. Most cases of recurrent genital herpes are caused by HSV-2, and approximately 50 million persons in the United States are infected with this type of genital herpes . Most persons infected with HSV-2 have not had the condition diagnosed. Many such persons have mild or unrecognized infections but shed virus intermittently in the anogenital area. As a result, most genital herpes infections are transmitted by persons unaware that they have the infection or who are asymptomatic when transmission occurs. Management of genital HSV should address the chronic nature of the disease rather than focusing solely on treatment of acute episodes of genital lesions.

The main point of this question though is to see if you could give me a 1 in X guess at the average per act transmission rate assuming the partner is infected, and no valtrex, condom, or antiviral anything involved. Thanks doc. Sexual transmission of herpes simplex virus type 2 (HSV-2) has been demonstrated from both symptomatic and asymptomatic reactivations in the infected partner. Daily antiviral therapy has been shown to decrease the frequency and amount of genital HSV shedding. Corey and colleagues tested daily valacyclovir for efficacy in preventing sexual transmission of HSV-2 from infected persons to their uninfected partners. The study enrolled monogamous, immunocompetent, heterosexual couples in which only one partner was infected with HSV-2, as demonstrated by Western blot analysis of anti–HSV-2 serum antibodies. Of the initial 4,034 couples screened, 1,385 asymptomatic partners already had serologic evidence of HSV-2 infection and were ineligible, and 799 of the source partners were symptomatic but had negative HSV-2 serology. After informed consent, 352 couples declined to participate, and 14 persons declined to take the study medicines, leaving 1,484 couples (37 percent) available for randomization. The infected source partner of each enrolled couple was randomized to receive valacyclovir in a dosage of 500 mg or placebo taken once daily for eight months.
