| Ching-yee, your hands will not be clean if you wash in this manner |
| There are many germs around in the shopping centre |
| we should wash our hands thoroughly |
| Then how should I wash them? |
| Ling, please demonstrate the correct method of hand washing |
| First, wet our hands with water |
| Then, get some liquid soap and rub hands together to make a soapy lather |
| Rub each part of our hands for at least 5 times |
| First, rub our palms |
| then back of hands |
| finger webs |
| back of fingers |
| thumbs |
| finger tips |
| and finally our wrists |
| Rub for at least 20 seconds |
| Then rinse hands thoroughly with water |
| Then dry hands with paper towel or hand dryer |
| Properly discard the used paper towel |
| That's it |
| If I cannot wash my hands with water and soap |
| can I use alcohol-based handrub instead? |
| Yes, you can |
| If your hands are not visibly soiled |
| you can use 70-80% alcohol-based handrub |
| It can effectively prevent cross transmission of infectious diseases via hands |
| The hand rubbing technique of using alcohol-based handrub is similar to hand washing |
| Use sufficient amount, around 3-5 ml of alcohol-based handrub |
| To cover all surfaces of your hands |
| we rub our palms |
| then back of hands |
| finger webs |
| back of fingers |
| thumbs |
| finger tips |
| and then wrists |
| Rub for at least 20 seconds until your hands are dry |
| Let the alcohol dry on your hands, don't wipe it off with paper towel |
| Check the expiry date of alcohol-based handrub before using |
| Let me give you a tip: we can sing birthday song while washing our hands! |
| Singing while washing hands? |
| If you are shy, you can sing in your heart |
| I am not that shy, let's sing and wash |
| Dr Lui, why is hand hygiene so important? |
| It is because our hands come into contact with many different pathogens every day |
| We cannot know the degree of contamination by inspection with our naked eyes |
| Many infectious diseases can be spread by unclean hands |
| hence hand hygiene is very important |
| We suggest to perform hand hygiene by either hand washing |
| or using alcohol-based handrub |
| We should wash hands with soap and water when they are visibly dirty |
| If our hands are not visibly dirty |
| alcohol-based handrub can give the same result and is very convenient too |
| KJ, do you know when should we clean our hands thoroughly? |
| Yes. Is it before and after we touch our eyes, mouth or nose |
| when respiratory secretions contaminate our hands, such as after coughing or sneezing |
| after touching public objects |
| before food preparation and consumption |
| after using toilet |
| before wearing mask; before or after taking off the mask? |
| Correct. You have answered very well |
