I just saw that Georgia can open gyms on Fri.
I hope all the old people votes won't affect reopening here in Fl.

I wonder if these people taking temperatures know what heat and exercise does to the core temperature. I did a 15 minute rubber band workout last night, I checked my temperature with one of the infrared temp things and it was elevated to 101.7. It stayed elevated for about 30 minutes afterwards. Much higher intensity workouts can increase the core temperature to as much as 104 degrees. Walking outside on a hot day can do the same. Just another senseless invasion of our privacy.
Not sure I am understanding how this works. I read the whole article and even the news release and all the described was, "The pandemic drone will be equipped with a specialized sensor and computer vision systems that can display fever/temperature, heart and respiratory rates, as well as detect people sneezing and coughing in crowds." Fever is simply an abnormal increase in body temperature. Most of the new monitors are infrared which measure temperature. i would suspect they use infrared technology in cameras but they don't say.
BackAtIt, I brought up body temperature because I was involved in a scientific debate recently over whether or not exercise induced rises in core temperature might help to fight off covid 19. We do know it is capable of fighting off other viruses especially respiratory viruses which is the reason most low intensity and medium intensity athletes have very few incidents of respiratory infections. So I wanted to see where my core temp went after exercise.
not sure how they are differentiating temp vs. fever. Probably temperature + other readings to separate temp vs. fever temp. Dragonfly the company makes this has said they differentiate the two
Seems this most likely didn't come from bats but someone who could have been working with the virus at a lab. Anyway, there was a study just released about That found that humidity, heat and especially Sunlight (UV) works to shorten the half life of this virus. Also remember the bodies natural response to infection is to raise the core temperature. This elevated body temperature sets in motion a series of mechanisms that regulate our immune system. So it is apparent that the increases we get from exercise aid in preventing viral and bacterial infections.Some are saying that this can't fight high temp....Have u read those reports, Tex?...If I remember correctly (which usally I don't),a bro from here mentioned in the corona thread that he didn't think high temp would fight this...I think he was thinking it came from bats and bats sport high temps twice a day...
Here is an article too, claiming that this virus has been altered to infect humans more efficiently than normal...

Here is a good study on exercise and URI's. As mentioned above, the head the body produces from exercise sets off the following mechanisms that help prevent bacteria and virus. Glucocorticoids (cortisol) increases while catecholamines (adrenaline etc) decrease lowering the amount of inflammation in the body, thus C-Reactive protein levels decrease. Is intensity increases the reverse takes place (Fig 1)
This article has provided evidence to support the hypothesis that moderate intensity exercise reduces inflammation and improves the immune response to respiratory viral infections. We hypothesize that acute and chronic moderate exercise induces a level of stress hormones that down-regulates excessive inflammation within the respiratory tract and aids in activating innate anti-viral immunity shifting the immune response towards a Th2 profile (Fig. 4),thereby balancing the Th1/Th2 responses to prevent an excessive Th1 immune reaction to these pathogens. Prolonged, intense exercise may do this as well but may shift the balance too much towards Th2 and away from Th1 actually allowing the virus to gain a better foothold and cause greater pathology. Further research is necessary to examine cellular and molecular mechanisms through which exercise modulates immune function. Additionally, human studies should attempt to elucidate the most common respiratory pathogens responsible for infections associated with high intensity exercise training and athletic competitions, and the methods they employ to evade immune response, as well as attempt to translate mechanistic studies to a human experimental model. Based upon the available evidence, moderate intensity exercise training should be used as an adjunct to other preventative measures against respiratory tract viral infection.
Checks and balances
Th1 - cytokines tend to produce the pro-inflammatory responses responsible for killing intracellular parasites and for perpetuating autoimmune responses. Th1 response is necessary in the early stages of viral infection, as it promotes rapid clearance of the virus.
Th2- include interleukins 4, 5, and 13, which are associated with the promotion of IgE and eosinophilic responses in atopy, and also interleukin-10, which has more of an anti-inflammatory response. In excess, Th2 responses will counteract the Th1 mediated microbicidal action. The optimal scenario would therefore seem to be that humans should produce a well balanced Th1 and Th2 response, suited to the immune challenge.
The big thing with covid 19 is there is a huge flood of Th1 levels (cytokine storm) in the later cycles which can have some harmful effects on the body leading to pulmonary edema and lung failure, and have liver, heart, and kidney damages . Moderate exercise seems to enable the body to keep a balance in Th1 and Th2 levels which fight off inflammation and avoid this harm high Th1 levels seem to cause. People that do not exercise or have preexisting disease like obesity/ diabetes have difficulty fighting off this flood of cytokines.
It gets really confusing when studying this stuff...I was always under the impression that they keep hospitals cold in order to help prevent bacterial growth/germs ect from spreading...Every operation I've had (that be many) it was always super cold in the or...I was always given that the cold help prevent bacterial growth/virual spreads....I had a biologist tell me that really what kills viruses/bacteria is the rapid change in temp, not the temp itself...Can't remember what the window for range of temp is, but it doesn't take much of a differential in temp to kill them...Is just the rapid change from one temp to another...
However, I tend to concur with u too...I know I haven't had the flu yet, or didn't know it if I did....I will occasionally get a cold at the change of season, but gone in a couple of days with vit c upload....Of course this is when I'm working out regularly...There have been times tho when I stalled on workouts and I would get 2-3 colds that would last 2-3 weeks in that year....Anyway, some say this virus can handle the heat, others are saying no....Thanks for the article, bro!....Good read!
BackAtit, this is a very good study but they are talking about instantly killing a virus though, not slowing the half life. Killing it of course is ideal. But you can kill it petty quickly with a light solution of bleach. The however, DHS study showed the following:
temps of 70-75 degrees, with 20% humidity and no sun - 18 hour half life.
temps of 70-75 degrees, with 80% humidity and no sun - 6 hour half life.
temps of 95 degrees, with 80% humidity and no sun - 1 hour half life.
temps of 70-75 degrees, with 80% humidity and summer sun - 2 minute half life.
Do you know that hospitals typically use UVA light sterilizing units in their HVAC systems, along with pressurized air control and Merv 17 air filters? .
