| Shopping centres are usually crowded |
| There may be babies and elderly people |
| thus proper infection control measures are essential |
| to safeguard the health of the community |
| I can see that many people take pictures or selfies here |
| They must be attracted by the beautiful environment here |
| which should look great on social media |
| Apart from the aesthetic design, we should ensure proper hygiene in all aspects |
| To prevent or control infectious diseases |
| appropriate infection control measures must be carried out promptly |
| by removing the pathogens or infective microorganisms |
| source of infection, route of transmission, and the susceptible host |
| so as to interrupt the chain of infection |
| I know that there are two tiers of infection control measures |
| Including standard precautions, and transmission-based precautions |
| KJ, standard precautions refer to the precautionary measures |
| that are applied when we may contact blood, body fluids, secretions |
| excretions, wounds and mucous membranes |
| regardless of whether the target is infected or not |
| These measures include hand hygiene, cough etiquette, environmental cleanliness |
| Proper use of Personal Protective Equipment (PPE) |
| and appropriate waste handling |
| Transmission-based precautions are additional measures |
| that we may adopt on top of standard precautions |
| They focus on preventing the spread of infectious diseases |
| through contact, droplet or the airborne route |
| of which, proper use of PPE plays a very important role |
