Rabies immunoglobulin utilization and delayed presentation following category III rabies exposure: a 10-year retrospective study in Hangzhou, China

Background

Rabies is an almost invariably fatal, vaccine-preventable zoonosis. Rabies immunoglobulin (RIG) is recommended for Category III exposures, yet real-world RIG utilization remains poorly characterized. This study examined temporal trends and factors associated with RIG utilization and delayed presentation among Category III exposure patients in China.
