“The reason to highlight these different outbreaks is to show you the commonality of outbreaks of COVID-19. All these infection events were indoors, with people closely-spaced, with lots of talking, singing, or yelling. The main sources for infection are home, workplace, public transport, social gatherings, and restaurants. This accounts for 90% of all transmission events. In contrast, outbreaks spread from shopping appear to be responsible for a small percentage of traced infections. (Ref)
Importantly, of the countries performing contact tracing properly, only a single outbreak has been reported from an outdoor environment (less than 0.3% of traced infections). (ref).”
Let’s all go outside. And stay there.
A scientist who writes clearly.
“Basically, as the work closures are loosened, and we start to venture out more, possibly even resuming in-office activities, you need to look at your environment and make judgments. How many people are here, how much airflow is there around me, and how long will I be in this environment. If you are in an open floorplan office, you really need to critically assess the risk (volume, people, and airflow). If you are in a job that requires face-to-face talking or even worse, yelling, you need to assess the risk. If you are sitting in a well ventilated space, with few people, the risk is low.”
“Fortunately, increasing your distance, decreasing the duration of your exposure, and improving the ventilation of the air around you can all lower your risk. And being outdoors generally helps you do all three.
‘The risks of virus transmissibility in the air outdoors is likely quite low in those contexts, although this risk hasn’t been definitively measured,’ Rasmussen said. ‘Outside, things like sunlight, wind, rain, ambient temperature, and humidity can affect virus infectivity and transmissibility, so while we can’t say there’s zero risk, it’s likely low unless you are engaging in activities as part of a large crowd (such as a protest). Solitary outdoor exercise is likely low-risk.'”
This, I think, is a key insight. And challenge:
“Psychologically, different people have different levels of tolerance for risk. For some people, any risk that can be minimized, should be, no matter how small. For others, the recommended 6-foot distance, with masks, and the known decay of both the amount and the infectiousness of the virus — that’s good enough.
‘The people who are 26-footers should know, though, that the 6-footers are not being foolhardy or endangering others unnecessarily,’ Kasten said.”
And likewise, “6-footers” should be as patient and kind as possible to those they perceive to be overly and unnecessarily cautious.
“Schmidt said when he was first sent a photo of the radar gun showing 308 km/h he thought the officer was joking and had been down at an airport training his laser on planes taking off.
‘This is ridiculous. This is unbelievable. This is irresponsible and I certainly hope this person will not be any position to drive a vehicle for a very long time.'”
