some viruses are readily inactivated by alcohol; however, some are not. Viruses consist of nucleic acid (either RNA or DNA) surrounded by a capsid (protein shell). Some viruses have an additional external layer or wrapping known as an envelope. The envelope is created from a piece of phospholipid membrane that comes from the infected host cell during the “budding” process when viral particles leave the infected cell. Enveloped viruses are referred to as lipophilic viruses, because of their lipid envelope, while nonenveloped viruses are referred to as non-lipophilic viruses.
Generally, enveloped (lipophilic) viruses are susceptible to alcohol: Herpes simplex virus (HSV), human immunodeficiency virus (HIV), influenza virus (Flu), respiratory syncytial virus (RSV), vaccinia virus, Hepatitis B and C viruses are considered susceptible to alcohols.
