Handwashing is one of the best ways to remove germs, avoid getting sick, and prevent the spread of germs to others. It’s quick, it’s simple, and it can keep us all from getting sick. Handwashing is a win for everyone… except the germs.
Based on what is currently known about this coronavirus, also called COVID-19, it is spread from person-to-person and happens most frequently among close contacts (within about 6 feet). The virus is transferred through respiratory droplets.
Coronaviruses are named for the crown-like spikes on their surface. The virus is enveloped in a bubble of oily lipid molecules, which falls apart on contact with soap.
Because the virus enters your body through the nose, mouth, or eyes, it is even more important that you refrain from touching these parts of your face with unwashed hands.
What is the best way to wash my hands?
At home or work, wash your hands often—and correctly:
Use clean, running water. Use warm water if it's available.
Wet your hands before applying soap.
Rub your soapy hands together for at least 20 seconds. Wash all surfaces well. This includes your wrists, palms, backs of hands, and between fingers.
Remove the dirt from and clean under your fingernails.
Rinse your hands thoroughly to remove all soap.
Dry your hands with an air dryer or a clean paper towel.
Turn off the faucet with a paper towel.
If soap and water are not available, an alcohol-based hand sanitizer can be used to clean your hands. When using this type of product:
Put the gel in the palm of one hand.
Rub your hands together.
Rub the product over all surfaces of your hands and fingers until they are dry.
How often should I wash my hands?
Hands should be washed often. This means more often than most adults and children actually do. Bacteria and other germs can only be seen under a microscope, so they can be anywhere. According to the CDC, it is especially important to wash your hands:
Before preparing food
Before and after treating an open sore, cut, or wound
After using the bathroom
After touching animals or animal waste
After changing diapers or cleaning up a child who has gone to the bathroom
After blowing your nose, coughing, or sneezing
After handling garbage
When hands are dirty
When someone around you is ill
What is the difference between cleaning and disinfecting?
Cleaning and disinfecting are two different things. Cleaning means using soap and water to remove dirt and most germs. Disinfecting means using cleaning solutions that have ingredients that kill bacteria and other germs. Many surfaces look clean, but maybe contaminated with germs.
The CDC recommends the following when cleaning or disinfecting:
Wear rubber gloves when cleaning up blood, vomit, or stool.
Wear rubber gloves when you have cuts or scrapes on your hand that make it easy for an infection to enter your body.
Read the directions on the cleaning product label, including the safety information.
First, clean the surface with soap or another cleaner and water. Note: Always store cleaning solutions and other household chemicals in their original containers. Keep them out of children's reach.
Second, use a disinfectant on the surface. Leave it on for a few minutes, depending on the manufacturer's directions.
Third, wipe the surface dry with a paper towel and throw the paper towel away. Or use a cloth towel that is washed afterward.
Fourth, wash your hands well, even after wearing gloves.
The two most important household areas to clean and disinfect correctly are the kitchen and bathroom. In the kitchen, bacteria from raw food can contaminate surfaces and food prep areas. Without correct cleaning, this can spread disease. Other important areas that need correct cleaning include children's changing tables and diaper pails.
