| Summary: | Dengue disease is still a major health problem in Indonesia, and occurs in
all provinces including Aceh. Incidence of the disease in Aceh had increased since 2011
till 2014. However, only limited data about the disease and its causative agent was
available. The disease is caused by dengue virus (DENV) which consists of four
serotypes (DENV-1, 2, 3, 4). We conducted surveillance in three regions in Aceh
province during January-March 2016, namely: Banda Aceh, Lhokseumawe and North
Aceh. A total 114 samples of dengue-suspected patients were tested serologically (IgM
and IgG, and NS1), and also inoculated in cell C6/36 for observation of CPE, then in
vero B1 for immunostaining assays. RT-PCR was performed from samples with NS1 and
or CPE and immunostaining-positive. DENV genotyping was performed by sequencing
and phylogenetic analysis of envelope (E) gene. To determine the growth characteristics
of Aceh’s DENV, replication kinetics of all three serotypes were measured by focus
assay methods. Comparation test for DENV replication rates with Kruskal-Wallis (α=
0.05)
Results: Based on serological data, 18 patients were primary infection and 60 were
secondary infection. A total 24 samples were positive PCR which DENV-2 was
predominant (76,2%), followed by DENV-3 (28,5%) and DENV-1 (9,5%). Genotyping
revealed circulation of DENV-1 genotype I and DENV-2 genotype cosmopolitan. In
Kruskal-Wallis test p=0.000.
Conclusion: Three serotypes (DENV-1 genotype I and DENV-2 genotype cosmopolitan
and DENV-3) were found to be co-circulating in Aceh between January and March
2016. Comparative analysis showed statistically difference rate of DENV replications
(p=0.000). |
