What does Community transmission (CT) mean?

CT happens when new cases in the last 14 days cannot be traced to those who have an international travel history when cases cannot be linked to a specific cluster.
The WHO guidelines further suggest four subcategories within the broader definition of CT.
CT-1 implies “low incidence of locally acquired, widely dispersed cases... and low risk of infection for the general population” with the highest, a CT-4 suggesting “very high incidence of locally acquired, widely dispersed cases in the past 14 days and very high risk of infection for the general population”.
India still does not label itself under the CT tag.
