Alcohol disinfection how long to kill the new crown virus can not be generalized, 75% concentration of alcohol in general 1-5 minutes or so can kill the new crown virus, if the concentration of alcohol is too low or too high, the inactivation time will be relatively long.
New coronavirus is currently the main clinical epidemic of one of the viruses, the modern medical research found that the new coronavirus to a certain concentration of alcohol have a high sensitivity, so alcohol disinfection is currently the life and clinical inactivation of the new coronavirus, to prevent the spread of the virus way. Alcohol disinfection how long to kill the new crown virus can not be generalized, need to be based on the concentration of alcohol used to determine the disinfection.
Currently, the concentration of alcohol used in clinical practice is 75%, which has been found to be very effective in destroying the proteins and nucleic acids in the neocoronaviruses and denaturing these substances. Usually, 75% concentration of alcohol in contact with the new coronary virus after about 1 to 2 minutes, will make it inactive, even if the contact with the human body generally will not cause infection, and after about 5 minutes can achieve the purpose of killing the new coronary virus. However, if the concentration of alcohol is too low, it may reduce the efficiency of destroying viral proteins and other substances, while if the concentration is too high, it may not be able to enter the virus, thus leading to prolonged inactivation time, or even unable to play a role in killing the virus.
To summarize, it is recommended that normal people always keep 75% alcohol at home, and use alcohol to disinfect themselves first when they go out and come home, so as to avoid carrying the virus home and causing the virus to spread.
