Title: | Measles epidemic in Southern Vietnam: an age-stratified spatio-temporal model for infectious disease counts | Authors: | NGUYEN, Trang FAES, Christel HENS, Niel |
Issue Date: | 2022 | Publisher: | CAMBRIDGE UNIV PRESS | Source: | EPIDEMIOLOGY AND INFECTION, 150 (Art N° e169) | Abstract: | Measles resurged in Vietnam between 2018 and 2020, especially in the Southern region. The proportion of children with measles infection showed quite some variation at the provincial level. We applied a spatio-temporal endemic-epidemic modelling framework for age-stratified infectious disease counts using measles surveillance data collected in Southern Vietnam between 1 January 2018 and 30 June 2020. We found that disease transmission within age groups was greatest in young children aged 0-4 years whereas a relatively high between-group transmission was observed in older age groups (5-14 years, 15-24 years and 25+ years groups). At the provincial level, spatial transmission followed an age-dependent distance decay with measles spread mainly depending on local and neighbouring transmission. Our study helped to clarify the measles transmission dynamics in a more detailed fashion with respect to age strata, time and space. Findings from this study may help determine proper strategies in measles outbreak control including promotion of age-targeted intervention programmes in specific areas. | Notes: | Nguyen, THT (corresponding author), Hasselt Univ, Hasselt, Belgium.; Nguyen, THT (corresponding author), Pasteur Inst, Ho Chi Minh City, Vietnam. thihuyentrang.nguyen@uhasselt.be |
