Bihar: 6 chickenpox outbreaks in week 11 of 2017, the most since week 16 of 2016.

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 chickenpox outbreaks, neither a rise nor a fall is better in itself, so the observatory marks this movement as unusual rather than good or bad.

46 consecutive earlier weeks were lower. It extends a run of new highests that began earlier.
