Epidemiological and spatial–temporal clustering characteristics of pertussis in Southwest China, 2013–2024
This study documents a substantial resurgence of pertussis in Chongqing from 2013 to 2024, characterized by a notable change in age distribution. Although infants (aged <1 year) maintained the highest notification rate, school-aged children (5-10 years) emerged as the largest case group in 2024. Consequently, establishing seroepidemiological surveillance to directly quantify population immunity is essential for designing targeted and effective control measures.
