Everything you need to know about washing your hands to protect against coronavirus (COVID-19)
Washing your hands can protect you and your loved ones.
Respiratory viruses like coronavirus disease (COVID-19) spread when mucus or droplets containing the virus get into your body through your eyes, nose or throat. Most often, this happens through your hands. Hands are also one of the most common ways that the virus spreads from one person to the next.
During a global pandemic, one of the cheapest, easiest, and most important ways to prevent the spread of a virus is to wash your hands frequently with soap and water.
Here’s everything you need to know about how to wash your hands the right way:
1. How do I wash my hands properly?
To eliminate all traces of the virus on your hands, a quick scrub and a rinse won’t cut it. Below is a step-by-step process for effective handwashing.
- Step 1: Wet hands with running water
- Step 2: Apply enough soap to cover wet hands
- Step 3: Scrub all surfaces of the hands – including back of hands, between fingers and under nails – from 40 to 60 seconds.
- Step 4: Rinse thoroughly with running water
- Step 5: Dry hands with a clean cloth or single-use towel
2. How long should I wash my hands?
You should wash your hands for at least 20-30 seconds. An easy way to time it is by singing the full happy birthday song, twice.
The same goes for hand sanitizer: use a sanitizer that contains at least 60% alcohol and rub it into your hands for at least 20 seconds to ensure full coverage.
3. When should I wash my hands?
In the context of COVID-19 prevention, you should make sure to wash your hands at the following times:
- After blowing your nose, coughing or sneezing
- After visiting a public space, including public transportation, markets and places of worship
- After touching surfaces outside of the home, including money
- Before, during and after caring for a sick person
- Before and after eating
In general, you should always wash your hands at the following times:
- After using the toilet
- Before and after eating
- After handling garbage
- After touching animals and pets
- After changing babies’ diapers or helping children use the toilet
- When your hands are visibly dirty
4. How can I help my child wash his or her hands?
Here are some ways you can help children wash their hands by making handwashing easier and fun for them:
Make it easy
Set up a stool to make it easier for smaller children to reach the sink by themselves. Place the soap within the child’s reach. A timer by the sink can help them count down from 20.
Make it fun
Sing a song together — like the ABCs or “happy birthday” — while washing hands. This can also help to keep you scrubbing for 40 seconds. Use a fun soap, something colourful, that foams well or smells good, or comes in an interesting shape.
Make it routine
Set a time for handwashing, like when your child gets home and right before eating or going to bed. Make sure they wash their hands after coughing and sneezing.
Help them understand
Teach them about how even though germs are invisible, they could still be there. When children understand why they need to wash their hands, they’re likely to continue doing so.
Make it a family affair
Set a good example by getting everyone at home to wash their hands at key moments too!
5. Do I need to use warm water to wash my hands?
No, you can use any temperature of water to wash your hands. Cold water and warm water are equally effective at killing germs and viruses – as long as you use soap!
6. Do I need to dry my hands with a towel?
Germs spread more easily from wet skin than from dry skin, so drying your hands completely is an important step. Paper towels or clean clothes are the most effective way to remove germs without spreading them to other surfaces.
7. Which is better: washing your hands or using hand sanitizer?
In general, both handwashing with soap and water and hand sanitizer, when practiced/used correctly, are highly effective at killing most germs and pathogens. Hand sanitizer is often more convenient when you are outside of the home, but can be expensive or difficult to find in emergency contexts. Also, alcohol-based hand sanitizer kills the coronavirus, but it does not kill all kinds of bacteria and viruses. For example, it is relatively ineffective against the norovirus and rotavirus.
8. What if I don’t have soap?
Using chlorinated water or hand sanitizer that contains at least 65% alcohol are the best second options if you do not have soap and running water. In cases where these are not available, using soapy water or ash may help remove bacteria, though not as effectively. If these methods are used, it is important to wash your hands as soon as possible when you do have access to handwashing facilities and avoid contact with people and surfaces in the meantime.
9. How else can I help stop the spread of the coronavirus?
- Use proper sneezing and coughing etiquette: Cover your mouth and nose with a flexed elbow or tissue when coughing or sneezing, dispose of used tissue immediately, and wash your hands
- Avoid touching your face (mouth, nose, eyes)
- Practice social distancing: Avoiding shaking hands, hugging or kissing people, sharing food, utensils, cups, and towels
- Avoid close contact with anyone who has cold or flu-like symptoms
- Seek medical care early if you or your child has a fever, cough or difficulty breathing
- Clean surfaces that might have come in touch with the virus, and generally clean surfaces more frequently (especially in public spaces)
