Alcohol is not a medical treatment, but is frequently used in health-care settings to disinfectant surfaces in order to prevent the transmission of common viruses or bacteria.[1]

Ethyl alcohol[edit | edit source]

Ethyl alcohol, also known as ethanol, can destroy any virus enveloped in fat, when used in the correct concentrations, including:

and some non-enveloped viruses, including:

Ethyl alcohol is not effective against the hepatitis A virus or polioviruses.[2]

Ethyl alcohol should be used at 60-80% concentrations.[2]

Isopropyl alcohol[edit | edit source]

Isopropyl alcohol, also known as isopropyl, can destroy any virus enveloped in fat, including the coronaviruses that cause COVID-19, SARS when used in the correct concentration, but unlike ethyl alcohol it cannot inactivate non-enveloped viruses.[1]

Isopropyl is also effective against a variety of bacteria, including:

Methanol[edit | edit source]

Methanol is not used in healthcare settings due to its low effectiveness against bacteria.[1]

Limitations of alcohol disinfectants[edit | edit source]

Surfaces must be cleaned before disinfecting with alcohol, which will remove the protein-rich materials that alcohol cannot penetrate.[3][2]

Alcohols are not recommended for sterilizing medical and surgical materials principally because they penetrate protein-rich materials, and they cannot inactivate the spores caused by some forms of bacteria.[2]

Alcohol-based hand sanitizer[edit | edit source]

Alcohol-based hand sanitizers (ABHS) are effective against many different types of viruses and bacteria; a 60% strength concentration is recommended for the virus causing the 2019-2020 coronavirus pandemic.[3] However, washing hands carefully soap and running water is more effective against coronaviruses, including the coronavirus that causes COVID-19.[3]

Alcohol-based hand sanitizers have limited effectiveness when incorrect technique is used, not enough sanitizer is used, and when they are not used consistently.[4]

Drinking alcohol[edit | edit source]

Drinking alcohol does not provide protection against coronaviruses, and drinking alcohol frequently or excessively can be extremely dangerous.[5]

ME/CFS[edit | edit source]

A number of different alcohol-based disinfectants are effective against common viruses and bacteria which have been reported to trigger ME/CFS.[citation needed]

Alcohol intolerance is also found in a significant proportion of ME/CFS patients. Some ME/CFS patients also develop mast cell activation syndrome, which involves an intolerance to alcohol and many other substances.
