The cold virus ‘hides’ and multiplies in the tonsils and adenoids, even in people without symptoms

A study reveals that the rhinovirus, causing the common cold, can infect immune cells in the tonsils and adenoids, remaining dormant for extended periods without symptoms. This persistence allows for unexpected transmission and triggers new outbreaks, particularly among children, who are a primary mode of transmission to grandparents.
