Commentary
A commentary post on surveillance as the public-health discipline that makes infectious disease signals visible enough to investigate.
Counting changes what can be seen
A Healthbeat article by Dr. Jay K. Varma uses disease counting as a way to explain why databases and surveillance systems matter. This post extends that reader path into the microsite's surveillance and emerging-infections hubs.
Why this is not just data work
Surveillance connects reports, laboratories, clinical signals, and public-health interpretation. The point is not to collect numbers for their own sake; it is to make patterns visible enough for investigation and action.
