How is this just starting? Here in Singapore, employers have been required to do twice-daily temperature checks for months.
This is the lowest of low-hanging fruit.
That's one of the most frustrating things about the response to this. Even now we don't have measures like having everyone wear face coverings, having temperature checks, limiting the number of people in establishments, etc., and it doesn't seem like anyone in power is advocating them at the moment. The response seems to be to first shut down the whole economy, then spend a few weeks thinking about what to do next.
