Disinfecting is still important, but it may not be enough. Lately, I've been seeing more and more written (including again today) about the increasing belief that tiny aerosolized droplets can carry the virus and stay airborne for hours, and are a primary cause (if not THE primary cause) of spread of Covid-19. Apparently, viral load is a major factor in transmission and even the seriousness of infection. And the 'viral load' a person is exposed to is a function of the amount of virus shed by an infected person in a given space, times the size of the space, times the amount of time spent there.
For example, someone with the virus who is just breathing (not talking, shouting or singing), in a very large room with high ceilings for just a few minutes, social distancing and wearing a mask, may not infect anyone else. (Whether or not others are wearing masks probably has an impact on their own risk, as well.)
Conversely, an infected person without a mask who spends a long period of time in a small enclosed space, talking loudly or shouting, sheds much more virus into that space, which becomes increasingly concentrated over time. Others who share that space are at risk, more so if they also don't wear a mask, and at an increasing rate the more time they spend there and the closer they get.
Sensible precautions ≠ fear; Sensible precautions = rational risk avoidance.
The greater the risk, the more important risk avoidance becomes - and right now, it seems clear that the WH is a high risk environment.
