Abstract:

Summary

Japanese encephalitis virus (JEV) is an important encephalitis virus in Asia, but there are few data on Malaysia. A hospital-based surveillance system for Japanese encephalitis (JE) has been in operation in Sarawak, Malaysia, for the last 10 years. JEV is endemic in Sarawak, with cases occurring throughout the year and a seasonal peak in the last quarter (one-wayanova, P < 0.0001). Ninety-two per cent of 133 cases were children aged 12 years or younger; the introduction of JE vaccination in July 2001 reduced the number of JE cases (84 in the four seasons prior to vs. 49 in the six seasons after, McNemar's test, P = 0.0001). After implementation of the programme, the mean age of infected children increased from 6.3 to 8.0 years (Student's t-test, P = 0.0037), suggesting the need for a catch-up programme.

Le virus de l'encéphalite japonaise (VEJ) est un important virus d'encéphalite en Asie, mais il y a peu de données sur la Malaisie. Un système de surveillance basé sur l'hôpital pour l'encéphalite japonaise (EJ) a été mis en place à Sarawak en Malaisie, durant les 10 dernières années. Le VEJ est endémique à Sarawak, avec des cas survenant toute l'année et un pic saisonnier dans le dernier trimestre (anovaunidimensionnelle, P < 0,0001). 92% de 133 cas étaient des enfants âgés de 12 ans ou moins. L''introduction de la vaccination contre l'EJ en juillet 2001 a réduit le nombre de cas d'EJ (84 au cours de 4 saisons précédentes contre 49 au cours des 6 saisons suivantes, test de McNemar, P = 0,0001). Après implémentation du programme, l'âge moyen des enfants infectés a augmenté de 6,3 à 8,0 ans (test t de Student, P = 0,0037), suggérant la nécessité d'un programme de rattrapage plus rapide.
