Why it matters
A record says how long it has been since the series was this high or this low. It puts a single value in the context of the whole published history.
For outbreaks reported, neither a rise nor a fall is better in itself, so the observatory marks this movement as unusual rather than good or bad.
Historical context
57 consecutive earlier weeks were lower.
