The UK and Simple Transmission-Limiting Actions?

The UK is experiencing yet another wave of Covid19 infections. Having just been for my vaccine booster (with the new 'improved' Omicron variant), I've had direct visual confirmation that transmission-limiting behaviours, by the UK's general public are now comparatively rare (https://www.theguardian.com/society/2022/oct/08/hand-washing-and-mask-wearing-covid-rules-we-would-be-wise-to-keep). Why is that the case? Clearly, mask-wearing and hand washing would still useful in helping to limit viral respiratory infection transmissions. People in Asian countries seem, however, much more relaxed about continuing to use these protections. A survey was carried out in Hong Kong, after their Covid19 pandemic was declared to be 'over'. 60-70% of respondents confirmed they would wear a mask in public spaces or the workplace, if they had 'flu or cold-like symptoms. 94% of those replying in this survey, still frequently washed their hands. People in the UK, may be more individualistic, with little sense of societal obligations and responsibilities. Here, folk taking precautions can actually receive public and media criticism. This is not helpful. A little precaution goes a long way. Certainly, individuals shouldn't be made to feel they are oddities, for simply trying to stop viruses being passed to people around them! This is individualism (rather than health and safety), 'gone mad'.
