https://www.ecologi.st/post/covid/ Evidence from phone data that W Cape adherence to lockdown has been quite strict thus lack of adherence is less likely to be the cause of the spike there. Thanks to Monomiat Ebrahim for the share.

Wondering if this means it is more likely to be:

1. A demographic feature such as age

2. A latitude feature – around the equator, COVID-19 has generally been less prevalent

3. A climate feature

4. High concentrations of “starters” leading to a critical mass for an epidemic
