Yes, tonsillitis can spread through kissing or sharing utensils. Tonsillitis is often caused by contagious viruses and bacteria—such as the Epstein-Barr virus (EBV), streptococcus, and common cold viruses—that are transmitted through saliva and respiratory droplets. Activities that involve exchanging saliva, including kissing, sharing drinks, using the same utensils, or sharing toothbrushes, can easily pass these germs from person to person.

If you're experiencing a sore throat, swollen tonsils, fever, or trouble swallowing, it's important to identify the cause quickly so you can get the right treatment and avoid spreading it to others. Take a free, instant, online symptom check to better understand your symptoms and confidently navigate your next steps.
