India: 14 chickenpox outbreaks in week 8 of 2025, the most since week 8 of 2018.

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.

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