Abstract

ABSTRACT
Background. Despite the availability of vaccine, measles remains a great challenge public health across the world. This study assessed the magnitude of measles outbreak and identify the associated factors of confirmed case health outcome in Mongolia. Methods. This study is a cross sectional survey using 2015-2016 data collected by the National Center for Communicable Diseases and the Ministry of Health in Mongolia. The study population was 3,787 confirmed cases of measles. Results. Out of 3787 subjects, 62.6% of subjects were aged under 6 years old, 50.6% were males, 80.4 % of subjects came from Ulaanbaatar (the capital city of Mongolia) and 69.3% were unemployed. In terms of clinical characteristics, almost all the subjects (98 % and above) experienced fever and rash; 62.5% experienced cough and around one-quarter had coryza and red eyes. Subjects from other cities or rural areas (OR=1.32, 95% CI: 1.12-1.57), unemployed (OR=1.44, 95%CI: 1.14-181) who had fever OR=2.22; 95% CI: 1.25-3.95) had rash (OR=2.16; 95% CI 1.14-4.89), had cough (OR=1.63; 95% CI: 1.42-1.87), had coryza (OR=4.46; 95%CI: 3.79-5.26), had red eyes (OR=2.2195% CI: 1.91-2.56) and with measles PCR positive (OR=2.28, 95% CI: 1.98-2.61) were more likely of being under negative health outcome compared to the reference groups. Conclusion. Higher prevalence of measles was observed in children aged under 6 years and adults aged 18 years and above. The risk of measles was higher among the cases with clinical symptoms. More intervention programs, including children and adult’s vaccination should be done to attenuate measles illness and reduce transmission.


RÉSUMÉ
Introduction. Malgré la disponibilité du vaccin, la rougeole reste un grand défi de santé publique dans le monde. Cette étude a évalué l'ampleur de l'épidémie de rougeole et identifié les facteurs associés à l'évolution de la santé des cas confirmés en Mongolie. Méthodes. Cette étude est une enquête transversale utilisant les données 2015-2016 collectées par le Centre national des maladies transmissibles et le ministère de la Santé de Mongolie. La population étudiée comptait 3 787 cas confirmés de rougeole. Résultats. Sur 3 787 sujets, 62,6 % étaient âgés de moins de 6 ans, 50,6 % étaient des hommes, 80,4 % des sujets venaient d'Oulan-Bator (la capitale de la Mongolie) et 69,3 % étaient au chômage. En termes de caractéristiques cliniques, presque tous les sujets (98 % et plus) ont présenté de la fièvre et des éruptions cutanées ; 62,5 % avaient de la toux et environ un quart avaient un coryza et des yeux rouges. Sujets originaires d'autres villes ou zones rurales (OR=1,32, IC 95 % : 1,12-1,57), chômeurs (OR=1,44, IC 95 % : 1,14-181) qui avaient de la fièvre OR=2,22 ; IC à 95 % : 1,25-3,95) avait une éruption cutanée (OR=2,16 ; IC à 95 % 1,14-4,89), avait de la toux (OR=1,63 ; IC à 95 % : 1,42-1,87), avait un coryza (OR=4,46 ; IC à 95 % : 3,79-5,26), avaient les yeux rouges (OR=2,2195 %, IC : 1,91-2,56) et avec une PCR positive pour la rougeole (OR=2,28, 95 % IC : 1,98-2,61) étaient plus susceptibles d'avoir un résultat de santé négatif par rapport aux groupes de référence.. Conclusion. Une prévalence plus élevée de la rougeole a été observée chez les enfants âgés de moins de 6 ans et les adultes âgés de 18 ans et plus. Le risque de rougeole était plus élevé parmi les cas présentant des symptômes cliniques. Davantage de programmes d’intervention, notamment la vaccination des enfants et des adultes, devraient être mis en œuvre pour atténuer la rougeole et réduire la transmission.
