Pertussis in Latin America and the Hispanic Caribbean: a systematic review

Introduction: Pertussis in Latin America continues to cause periodic epidemics with substantial morbidity particularly among young children. The disease has persisted despite long-standing vaccination programs in the region. Areas covered: We conducted a systematic review to characterize the recent epidemiology of pertussis in Latin America and Hispanic Caribbean. We undertook a holistic approach and attempted to include all available data concerning pertussis that may explain the changing dynamics of the disease. Expert opinion: There are wide disparities in the reported annual incidence rates of pertussis both within and between countries in the region. General trends in pertussis incidence are difficult to ascertain due to the heterogeneity in the epidemiological data. Available data suggests that the disease burden has changed over the years such that now it predominantly affects those 10 Latin American countries currently recommend vaccination of pregnant women.
