Antiviral Therapy T2 Rudolph's Pediatrics, 22e YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-149723-7 LK accesspediatrics.mhmedical.com/content.aspx?aid=7024440 RD 2024/10/11 AB Advances in molecular virology, with the identification of viral-specific enzymes, led to the development of a number of antiviral agents. Effective antivirals currently are available for the management of infections caused by herpes simplex virus (HSV), varicella-zoster virus (VZV), cytomegalovirus (CMV), hepatitis B and C viruses, influenza A and B viruses, and human immunodeficiency virus (HIV). To maximize therapeutic efficacy, treatment should be initiated as early in the course of infection as possible. Under some circumstances (eg, recurrent herpes simplex virus infections and exposure to influenza virus), antivirals may be effective in the prevention of infection. Development of resistance to antivirals is emerging as a problem, especially in the immunocompromised host population and more recently with influenza viruses circulating in the general population.
