First Aid notes that the HBV virion enzyme is a DNA-dependent DNA polymerase whereas UW says RNA-dependent DNA polymerase. Which one is correct? Also, FA says that acyclovir has no effect on latent forms of HSV and VZV but UW says that daily valacyclovir, acyclovir, or famcyclovir suppress reactivation of latent HSV infection. Which is correct? Thanks ahead of time.
