A US hantavirus case is retracted as a false positive, shrinking the outbreak count from 11 to 10 and underscoring the diagnostic confusion that can plague rare disease surveillance. This retraction makes the count 20% lower than the typical annual outbreak, with only one confirmed case appearing per month.

The Good Omens finale mostly sticks the landing, according to critics, closing out the adaptation with a blend of apocalyptic wit and character closure that satisfies despite a few missteps.
