In reply to minimike:
A colleague who lives in Alva tells me their neighbours had a party, where everyone present went on to develop covid (I think he said 19 people, but that rather assumes that everyone owned up), and of course they took it home to their families.
There's also a significant outbreak in Sauchie, which may or may not be related. As usual, the Alloa Advertiser has its finger on the pulse.

Clacks only has a population of just over 50,000 - so a couple of significant outbreaks like these have a large effect on the 'per 100,000' rate.
