Abstract

Abstract: Dengue hemorrhagic fever is one of important communicable diseases in Thailand. There was a big outbreak again in the country in 2013. On 15th May 2013, Bureau of Epidemiology (BoE) was notified that there were 103 cases from 4 clusters of dengue cases during 20th April to 7th July 2013 from Ubon Ratchathani. A team from Bureau of Epidemiology was sent to conducted field investigation. The objectives of this investigation are to analyze and describe epidemiological characteristics of the outbreak in the province particularly in two districts with highly active outbreak during June – July 2013, identify the important containers for mosquito larva.
Methods: Analysis and descriptive study was performed. Provincial Dengue case list from Provincial Health Office, Ubon Ratchathani and Medical record (ICD-10: A90-91) from Khueang Nai and Det Udom hospitals from January to July 2013 were reviewed. Acute serum from currently admitted cases during 16 - 27 July was collected for serotype for identifying container and larva surveys were conducted in 7 villages from the two districts.
Results: There were 1,642 cases in Ubon Ratchathani during January-July 2013. Attack rate was 90.6 per 100,000 populations, highest among age group of 13-18 years (289.4) and followed by 5-12 years (278.7). Among those cases, 48% were male. Forty five percent of the cases were diagnosed as Dengue Fever (DF), 47% as Dengue Hemorrhagic Fever (DHF), and 8% as Dengue Shock Syndrome (DSS). In Det Udom hospital, 126 cases were reported. Among them, DF, DHF, and DSS were diagnose 43%, 53% and 4%, respectively. For Khueang Nai, 202 cases were reported. DF, DHF and DSS were diagnosed 79%, 21% and 0% respectively. From seven serum samples collected, 1 sample was positive for DEN-3. Both indoor and outdoor water containers were equally important. Majority of potential breeding containers are outdoor while more larva was found among indoor containers. High importance containers are water container, other container, toilet cement tank, drinking container, tyres and cabinet leg cover respectively. All index at Khueang Nai’s are higher than Detudom. However, all indexes are too over standard in all villages, it makes the high risk for outbreak in the future.
