But what is interesting is that the current lockdown in Norway killed the flu with season ending abruptly.
- dragonwriter 6y agoThat's not surprising! The lockdown is a general-purpose counter to droplet/airborne-communicable diseases, it's not done for seasonal flu because the cost is seen as disproportionate to the known benefit. Stopping other communicable diseases is an expected side effect of the COVID-19 lockdowns.
