It’s an epidemic if a number people in one location are diagnosed with measles where previously zero people were diagnosed with measles.
Your comment shows a lack of concern and also ignorance as to what an epidemic is.
Epidemics are not measured by the number of dead - they are measured by the number infected in one specific location.
Measles were largely eradicated in the developed world due to vaccines.
A healthy child dying of this illness is utterly tragic.
