The ability of a pathogenic virus to lie dormant within a cell (latent infection). These studies were designed to investigate whether treatment of latently infected animals with a TK inhibitor altered the natural history of recurrent HSV disease. Romeu 0 1 2 3 4 5 G. A total of 52 subjects were excluded from the efficacy analysis because most had recurrent disease. austeni Newstead (Diptera: Glossinidae) on the Kenyan coast. Injection with prescription opioids was common (88.7% lifetime, 68.4% in past 6 months).” “Two forms of lifetime substance injection were independently associated with HCV seropositivity: injecting prescription opioids (adjusted odds ratio [AOR] = 2.22; 95% confidence interval [CI] = 1.13, 4.35) and injecting cocaine (AOR = 2.13; 95% CI = 1.31, 3.45; Table 2)” “….little is known about injection drug use in the rural United States other than that it is becoming more prevalent with the emergence of nonmedical prescription drug use. HSV-2/HIV co-infection was common in both time periods, with an average (over the two time periods) of 80% of HIV negative females infected with HSV-2, an average of 43% of HIV negative males infected with HSV-2; an average of 97% of HIV positive females also infected with HSV-2 and an average of 67% of HIV positive males also infected with HSV-2.

The antiviral mechanism of GA appears to be associated with Hsp90 inactivation and cell cycle restoration, which indicates that GA exhibits broad-spectrum antiviral activity. The weak cytotoxicity, strong viral inactivation as well as attachment inhibition activity enable EGP to be a virucide candidate for HSV therapy, especially for drug-resistant strains.
