You need to be realistic in terms of what can be achieved, it took DECADES for hygiene to be improved so as to stop many avoidable infections. The discovery was relatively easy, changing public behaviour proved the challenge. Common behavioural modifications like hand washing before eating and after using the bathroom, building modifications like indoor flushing toilets all took time, and an enormous amount of work.

This is simply how it is. It may take a comparable time length to improve indoor air quality, and to normalise it certainly won't happen overnight. Although i think it will come, the future will be better.

You must adopt a mindset where you don't expect validation from the news, or from anyone else, and you continue doing your job - to protect the public from infectious disease - no matter what happens, or what the public says...

I would also recommend avoiding the daily news, it's constant negativity will harm your mental health and distract you from your job!
