IPA: /nɒn.kənˈteɪ.dʒəs/
KK: /nɑnˈkɒn.tɪ.dʒəs/
This word describes a condition or disease that cannot be spread from one person to another.
The doctor confirmed that the illness was noncontagious, so there was no need to isolate the patient.
Noncontagious → It is formed from "non-" (meaning not) and "contagious" (from Latin "contagiosus", meaning touching or transmitted by contact). The word "noncontagious" means not capable of being transmitted by contact or not spreading from one person to another.
Think of 'not' ('non-') being added to 'contagious', which means something that cannot be spread through touch or contact.
