Well, thanks; but I still don’t know what you were responding to...
I was responding to your message in which you wrote:
“I don’t understand how screening for high temperature helps - it can identify actively ill people, but can’t you be infected with something for a while before you develop symptoms?”
In my original post, I mentioned masks and scanning for high temperatures. Those two items are just two of many items to slow down the spread of this virus. They can help reduce the risk of potentially getting the virus.
