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. It is well known that hand hygiene is a crucial factor in the control of health care-acquired infections (HCAIs) (Pratt et al, 2001). They are also effective against certain enveloped (lipophilic) viruses, such as HIV, influenza, respiratory syncytial virus, and herpes simplex virus. Hepatitis B and C are also susceptible to alcohol but are killed less readily and require at least 60-70 per cent alcohol for effectiveness (Sattar et al, 2001). Similarly Girou et al (2002) compared the efficacy of hand rubbing with an alcohol-based solution versus handwashing with antimicrobial soap during the delivery of routine patient care, including caring for patients with MRSA.
These include alcohols, chlorine and chlorine compounds, formaldehyde, glutaraldehyde, ortho-phthalaldehyde, hydrogen peroxide, iodophors, peracetic acid, phenolics, and quaternary ammonium compounds. These alcohols are rapidly bactericidal rather than bacteriostatic against vegetative forms of bacteria; they also are tuberculocidal, fungicidal, and virucidal but do not destroy bacterial spores. In addition, it provides specific recommendations to promote improved hand-hygiene practices and reduce transmission of pathogenic microorganisms to patients and personnel in health-care settings. APIC guideline for handwashing and hand antisepsis in health care settings. New studies of the in vivo efficacy of alcohol-based hand rubs and the low incidence of dermatitis associated with their use are reviewed. However, depending on the alcohol concentration, the amount of time that hands are exposed to the alcohol, and viral variant, alcohol may not be effective against hepatitis A and other nonlipophilic viruses. Hand sanitizer has been recommended but the bottles say, Effective against bacteria, with no mention of viruses. There have been some studies done over the years and the conclusion is washing your hands with soap and water is still probably the best idea. Viruses in this category include HIV, influenza, hepatitis B/C and herpes.
Most alcohol-based hand antiseptics contain either ethanol, isopropanol or n-propanol, or a combination of two of these products. It has in vitro activity against enveloped viruses such as herpes simplex virus, HIV, cytomegalovirus, influenza, and RSV, but significantly less activity against non-enveloped viruses such as rotavirus, adenovirus, and enteroviruses. Will alcohol gell kill herpes virus – Getting the right size Euros just over a. They are also effective against certain enveloped (lipophilic) viruses, such as HIV,. Hepatitis B and C are also susceptible to alcohol but are killed less readily. if alcohol hand gel was ineffective in destroying micro-organisms as reported by. Alcohol-based hand sanitizers are effective against bacteria and the efficacy of Purell’s 62 percent alcohol in killing these specific viruses is. The concept of antibacterial hand gels, or hand sanitizers, was postulated by Lupe Hernandez, RN in 1966 when she discovered alcohol could be delivered via gel. Antibacterial hand gels come in one of two forms: alcohol based and alcohol free. Isopropyl and ethyl alcohol together have also been proven effective against the viruses causing hepatitis B, herpes and HIV. Additional inactive ingredients may include carbomer, aminomethyl propanol, isopropyl myristate, or tocopheryl acetate.

Alcohol rub sanitizers kill most bacteria, and fungi, and stop some viruses. HIV,. Hepatitis B and C are also susceptible to alcohol but are killed less readily. if alcohol hand gel was ineffective in destroying micro-organisms as reported by. Alcohol-based hand sanitizers are effective against bacteria and the efficacy of Purell’s 62 percent alcohol in killing these specific viruses is. There are at least two types of HIV virus: HIV-1 is the cause of AIDS, and HIV-2 is a related group of viruses found in West African patients that is less easily transmitted. Receptive partners are at greater risk for transmission of any sexually transmitted disease, including HIV. Alcohol-based hand sanitizers are not effective against all pathogens, notably the spores of C. Rinsing hands with an antiseptic agent was believed to be less effective than handwashing with plain soap and was recommended only in emergencies or in areas where sinks were not available. Hepatitis B virus (HBV) is somewhat less susceptible but is killed by 60 70 alcohol; hepatitis C virus (HCV) also is likely killed by this percentage of alcohol. Then, an antiseptic hand rub, using an alcohol-based hand sanitizer, can be applied to prevent pathogen transmission. Chlorhexidine has in vitro activity against enveloped viruses such as herpes simplex virus (HSV), human immunodeficiency virus (HIV), cytomegalovirus, and influenza, but substantially less activity against nonenveloped viruses. Studies in a number of research journals show us that EGCG protects human cells from infection of HIV, herpes, norovirus, hepatitis B and C viruses, human papilloma virus, even Ebola, according to recently published antiviral research by the U. Most sanitizers kill bacteria and some viruses with alcohol, which evaporates in about 20 seconds. Most bacteria can be killed by alcohol-based sanitizers, but in order to effectively kill viruses, the concentration of alcohol must be very high, or about 90 percent,, which is dangerously flammable. Fulfills the requirement for 7 hours of HIV AIDS training for licensure of healthcare professionals in the state of Washington.
