The amount of cooling varies based on need. The only real difference is where you spend your time; In an mall, bar or restaurant, or at home. People in any climate with any sense are not going to the mall, bars or restaurants. People led and believing in idiot leaders will gladly do so.

But a lot of kids, including under 5, in Seattle, yes, are still going to preschool or day camps. I'm not bashing parents who send their kids to preschool or camps. This thing with masking up is an illusion. And, for how long are we going to do it? Until there is a vaccine?

It looks like RH may be more important than temperature, with lower RH associated with higher transmission rates. Most indoor air control (whether AC or heating) reduces RH. But if you aren't sharing indoor space with people who could transmit the disease, you aren't going to get sick--so this remains about social distancing and mask use.

That coupled with many states re-opening and in some cases going back to business as usual, and this is what you get. Other countries around the world that are doing well have unified leadership and citizens who don't all believe everything is a hoax. And many of these countries have hot temperatures and homes/businesses with air conditioning. Let's spend less time on the minutia of hot vs. cool weather, air conditioning, etc, and more time focusing on the real problems this country is facing. No leadership, nobody on the same page equals chaos and a virus that will not go away.

Just had to say that. I like ya Cliff but your answer is speculative at best at this point. Without an ACTUAL study that controls for all other possible causes of transmission you really don't have a clue, well probably more of a clue than I but still... we all want definitive easy answers to everything. COVID-19 has a few. Airflow matters. Aerosolizing (spelling?) is now being found to be a HUGE factor. I can see air conditioning having a greater affect on aerosolizing. No doubt the simple facts (ah simple) that folks are congregating more, in closer proximity with no masks, provides ample opportunity for this little bugger to latch on and spread. Ya politics have seemingly influenced unwise decisions not to mask. There are so many factors that favor the virus to spread in those states that pointing to one simple thing does not mean one simple answer. The longer you stay in aerosolized air the more you are open to the virus invading. Airflow, airflow, airflow. Be kind to others and wear masks. Wash, wash, sanitize!!!<br />VanZandtGrrlhttps://www.blogger.com/profile/02871709100770080842noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-38358428713782814342020-07-16T07:44:06.467-07:002020-07-16T07:44:06.467-07:00I agree.

They pull air from that room and disperse it to other rooms in the building. Most people walk by this room and don't even know it's there. Air is not pulled from one room full of people and pushed to another room of people. And the units have filters, probably not hepa,but they're dense. I would like to see some research on viruses making it through ac unit filters and ducts when the virus is in the ac unit enclosure, outside the enclosure, even down the hall.

Oregon, where I am at, has had strong safe distancing requirements, regardless of bar or restaurant or wherever people gather. If you are in a place with AC, but wear masks and maintain distance, I doubt AC would play too much of a role compared to if you allow no masks and don't care about crowds. And the level correlation between outbreaks and crowds is much higher than any other metric.Anonymoushttps://www.blogger.com/profile/03650556309006432058noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-15423456615615163282020-07-14T10:46:02.560-07:002020-07-14T10:46:02.560-07:00Be thankful for a man like Cliff Mass, this inform...Be thankful for a man like Cliff Mass, this information, real facts and studies is very hard to find and not available to most people.

Admittedly this is driven by "correlation is not causation", but so is much of this article. Moreover, just because some of the worst counties are run by Democrats" does not mean that Republican government is not a driving force for some of the problem, as state governments are probably more powerful than local or the federal government in Covid 19 leadership. The counties you note that have high infection rates and Democratic local government, which are Predominately "Democratic", and have high infection rates, are also heavily populated by minorities, Latinos in particular. You can see this play out in Imperial Valley in California and Eastern Washington. Another words, this could be a problem of Multicollinearity (Which is probably going to be a problem with many variables) or a data set that is not detailed enough. Thus, it probably would have been beneficial to put a county map next to a state map, as this would provided more detailed information. <br /><br />You could also run a multivariate model and then evaluate the correlation coefficients and multicollinarity. Then you could put the political correlation coefficients on state and county maps, color them, and see how they line up to political leadership at the top of the state or at a local level. If you wanted to take perhaps a better snapshot of variables that probably have a more direct effect on virus spread, but is somewhat related to politics, look at the demographic characteristics age, race, mask wearing, and the nature of closings in a given state and county.Nerka2https://www.blogger.com/profile/17464746800348428442noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-14442466462468478882020-07-14T09:42:29.107-07:002020-07-14T09:42:29.107-07:00At a certain point, we take the risk and re-open t...At a certain point, we take the risk and re-open the economy.
