Abstract:
BACKGROUND: Vietnam has a high burden of dengue fever (DF) and recently face the emergence of zika. The Ministry of Health issued a national guideline for integrated sentinel surveillance (ISS) of DF, chikungunya and zika that is based on the current DF sentinel surveillance system. The thesis is to provide more evidence on characteristics of vectors, incidence and distribution of the diseases and the points for improvement of current DF surveillance for better implementation of the ISS of three diseases. METHODS: Literature review was conducted with peer-reviewed articles, reports and gray literatures in English and Vietnamese were used to complete the thesis. The criteria for assessment of current DF surveillance system was develop by World Health Organization. FINDINGS: Aedes aegypti is the primary vector of the three diseases while Aedes albopictus plays certain role in DF and chikungunya transmission. Aedes malayensis is a potential vector of DF and chikungunya but its distribution is unknown in Vietnam. The distribution of the vectors helps explain the pattern of the diseases. DF had the highest incidence of 248, 314 and 330 per 100.000 population in the north, central and the south, respectively. Chikungunya and zika remain little known with the various proportions between studies using different laboratory tests. The weaknesses of current DF surveillance were in timeliness and completeness of case notification. CONCLUSIONS: The ISS of the three diseases should base on the distribution of the diseases and active vector surveillance should be added to enable the ability to predict the occurrence of outbreak in human. The weaknesses of current DF surveillance should be overcome to avoid missing cases and late response.
