• Definition of criteria for offering immunoglobulins as post-exposure prophylaxis.
• Clarification of contact tracing procedures and management strategies for healthcare workers.

Main Results:

• The guideline offers a precise definition for immunoglobulin administration.
• It clarifies the contact tracing process for measles cases.
• It provides recommendations for healthcare personnel with uncertain measles immunity.

Conclusions:

• The new guideline aims to make measles contact tracing more efficient, aligned, and equitable.
• Implementation is expected to improve the control of measles outbreaks in Sweden.
• Standardized protocols enhance public health response to highly contagious diseases.
