The mid-level in this range is about 61 million people infected with 2009 H1N1. The other study included 11 patients with localized varicella zoster infections.

There were 749 pregnancies followed in women exposed to systemic acyclovir during the first trimester of pregnancy resulting in 756 outcomes. The occurrence rate of birth defects approximates that found in the general population. However, the small size of the registry is insufficient to evaluate the risk for less common defects or to permit reliable or definitive conclusions regarding the safety of acyclovir in pregnant women and their developing fetuses.

The inhibitory activity of acyclovir is highly selective due to its affinity for the enzyme thymidine kinase TK encoded by HSV and VZV. This viral enzyme converts acyclovir into acyclovir monophosphate, a nucleotide analogue. The monophosphate is further converted into diphosphate by cellular guanylate kinase and into triphosphate by a number of cellular enzymes. In vitro, acyclovir triphosphate stops replication of herpes viral DNA. This is accomplished in 3 ways: 1 competitive inhibition of viral DNA polymerase, 2 incorporation into and termination of the growing viral DNA chain, and 3 inactivation of the viral DNA polymerase.
