COVID suggestions keep evolving. I did a little analysis in July, mostly focused on the question as to how we should have lunch at work… inside, outside,\u00a0 distanced, etc… Here’s what I came up with:<\/p>\n
There’s no perfect answer but here’s what my research is digging up. My own input at the end.<\/p>\n
CDC on “universal masking” in schools<\/a> – If community COVID levels are “high”, there should be “universal masking”. Levels are high in Marin<\/a> and most of California.<\/p>\n
CDC on colleges and masking<\/a> – Wear a mask when you’re indoors. When outdoors, you don’t need a mask unless you’re in “close contact” with people. “Close contact<\/a>” is defined as within 6 feet of another person for greater than 15 minutes if you’re unmasked, or 3 feet if you’re masked<\/p>\n
CDC on building ventilation<\/a> To paraphrase a long page: more ventilation, more outside air is always good. Use fans to get rid of dead air spots but don’t blow air from one person onto another. HEPA filters are good in small spaces. Improving HVAC filters is good but not at the top of the list<\/p>\n
A google search for “study covid restaurant” turns up lots of articles saying that dining is a risky activity. A notable issue: a case where a strongly blowing air conditioner infected people 21 feet away from one another with just 5 minutes of mask-off time.<\/p>\n
