Why 70 Percent Alcohol Disinfects Better Than 91 Percent, According to a Microbiologist

Alcohol percentages

  • To fend off bacteria, a 70 percent alcohol solution with water in it allows it to cross a cell membrane and kills the entire cell.
  • Viruses with an envelope structure, including the new virus, can be deactivated by alcohol solutions of 60 percent.
  • Any concentration of alcohol won't effectively target the norovirus.

Rubbing alcohol

Depending on what kind of germs you’re trying to kill, 70 percent alcohol is probably more effective than 91 percent for disinfecting.

A 90 percent alcohol solution is too powerful in some cases. It kills the outside of the cell before it can get into the inside and kill the actual germ.

Prevention is essential

  • Wash your hands often for at least 20 seconds.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
  • Clean and disinfect frequently touched objects.
  • Stay home when you are sick.
  • Contact a health worker if you have symptoms; fever and a dry cough are most common.
  • Don't touch your face.
  • Don't travel if you have a fever and cough.

The top way to clean our hands

Washing your hands with soap and water is the top way to clean our hands. If soap is not available, using a hand sanitizer with at least 60% alcohol can help.
When you wash your hands with soap and water, you’re wiping viruses off your hands and sending them down the drain. The whole process is actually annihilating the viruses, rendering them harmless.

Contaminated surfaces

  • The virus can be detected in aerosols (airborne droplets smaller than five micrometers) for up to three hours.
  • On copper, for up to four hours.
  • On cardboard, for up to 24 hours.
  • On stainless steel or plastic, for up to three days.

The virus particles on any surface decrease rapidly at the start, then slowly approaches zero over time.

Touching or eating contaminated food

If a food worker coughs over your food while preparing it, although really gross, your risk of contracting the disease that way is minimal.

According to a 2018 overview of respiratory viruses, the virus reproduces along the respiratory tract. It is a different pathway than the digestive tract food follows when you swallow it.

Even if you handle contaminated food and then deposit the virus along your respiratory tract, it's highly unlikely to get sick this way.
