What does the suffix -phylaxis mean in medical terminology?

The suffix -phylaxis in medical terminology refers specifically to protection against disease. This is derived from the Greek word "phylaxis," which means "protection" or "guarding." It is commonly used in terms such as "prophylaxis," which refers to measures taken to prevent disease or illness, such as using vaccinations or administering antibiotics to prevent infections. Understanding this term is crucial in medical contexts where prevention plays a key role in patient care and public health strategies.

The other options do not capture the essence of this suffix, as they relate to different concepts in medicine: measurement pertains to diagnostics, reconstruction relates to surgical procedures that modify tissues, and a surgical procedure refers to interventions without implying preventive measures.
