[quote=ltsdd]At some point the health officials going to have to realize the thermometer guns are mostly useless as a line of defense. If checking for someone’s body temperature is all they do then we (US) are not safe. We’re told that a carrier and spreader may not exhibit any symptoms (fever, etc..) for up to 19 days. How useful is that thermometer? Closing up borders sounds drastic but that may have to do until all these smart doctors actually know what they are dealing with. I think it’s mostly speculation on their part up to this part wrt to what the virus is and how exactly it’s spreading.[/quote]

There’s really no fullproof way to check for this. You definitely won’t catch people that don’t have symptoms yet. However, the reason for the thermometer guns is it at least you can try to catch the ones already exhibiting symptoms.
