Undersecretary for Science and Technology, Bill Bryan said Isopropyl alcohol will kill the virus on surface in 30 seconds

Isopropyl alcohol is a disinfectant which kills bacteria and viruses on surface, but whether it kills the virus in 30 seconds is yet to be confirmed.

White House coronavirus task force briefing by Bill Bryan, the acting homeland security undersecretary for science and technology, said isopropyl alcohol will kill the virus in 30 seconds with no manipulation and rubbing.

The World Health Organisation in its technical brief said that coronavirus on the surface will be easily be cleaned with common household disinfectants that will kill the virus. Further, studies show that the COVID-19 virus will survive for up to 72 hours on plastic and stainless steel, less than 4 hours on copper and less than 24 hours on cardboard.

National Library of Medicine states that isopropyl Alcohol is an isomer and that is a colourless liquid having disinfectant properties and the exact mechanism of isopropanol's disinfecting action is not known, it might kill cells by denaturing cell proteins and DNA, interfering with cellular metabolism, and dissolving cell lipoprotein membranes. Isopropanol has been used in soaps and lotions as an antiseptic and also used in the manufacturing of acetone and its derivatives as a solvent.

Centres for Disease Control and Prevention, states that 70 per cent isopropyl alcohol is not effective against adenovirus capable of causing epidemic keratoconjunctivitis. Isopropyl alcohol and ethyl alcohol have been excluded as high-level because it is inactivated against hydrophilic viruses.

Isopropyl alcohol acts as a disinfectant but whether it is effective against the COVID-19 on the surface by killing it in 30 seconds is not known as Isopropyl alcohol evaporates more quickly.

The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
