Background: The serotype of the virus that causes infection in a person can influence the severity of the dengue disease experienced so it is necessary to monitor and understand the dengue virus serotypes circulating in an area. Method: We searched for studies through two electronic databases (Pubmed and Scince direct). In the first stage, database search, 74 studies were obtained. The criteria for including studies were four human dengue virus serotypes published in 2013 {\textendash} 2023. In the final search there were 10 studies included. Results: Serotypes DENV-1, DENV-2, DENV-3 and DENV-4 have been reported in Singapore but DENV1 and DENV-2 are the main causes of dengue cases in this country. Serotypes DENV- 1, DENV-2, DENV-3 and DENV-4 have been reported in Indonesia but the prevalence of certain serotypes can vary from year to year and between regions in the country. Serotypes DENV-1, DENV-2, DENV-3 have been reported in Nepal but DENV-2 is found in high altitude and cold weather areas. Serotypes DENV-1, DENV-2, DENV-3 and DENV-4 have been reported in Pakistan but serotype DENV-1 is the main cause of dengue cases in this country. Serotypes DENV-1, DENV-2, DENV-3 and DENV-4 have been reported in India, however serotype DENV-4 was found to be the main cause of dengue cases both alone and in combination with dengue causes in this country. Serotypes DENV-1, DENV-2, DENV-3 and DENV-4 have been reported in Thailand but serotype DENV-2 is the main cause of dengue cases in this country. Serotypes DENV-1, DENV-2, DENV-3 and DENV-4 have been reported in Sri Lanka but serotype DENV- 2 is the main cause of dengue cases in this country. Serotypes DENV-1, DENV-2, DENV-3 and DENV-4 have been reported in China but serotype DENV-2 is the main cause of dengue cases in this country. Conclusion: Countries in Asia remain endemic for all four DENV serotypes, although some genotype- related evolution has been found in certain strains.

Introduction: Dengue virus (DENV) infection is general mosquito-transmitted viral taint. It can lead to the dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). Dengue is a solemn illness with no endowed antiviral medication or recognized vaccine. Therefore, we aimed to investigate the activity of Annona squamosa leaf extract (ASLE) against dengue virus type-2 (DENV-2) isolated from Surabaya, Indonesia in 2013 (NCBI accession number: KT012509). Methods: In this study, the antiviral activity of ASLE was evaluated against DENV- 2 in Vero cells using Viral ToxGlo{\texttrademark} Assay. In addition, we used CellTiter-Glo{\textregistered} Luminescent Cell Viability Assay to set the amount of viable cells in culture based on quantitation of the ATP. Results: DENV-2 replication inhibited by ASLE in Vero cells with IC50 = 73.78 μg/mL and SI = 4.49 when cells were treated two days after virus infection, whereas its CC50 for cytotoxicity to Vero cells was 331.54 μg/mL. Interestingly, this is the first report on the investigation of ASLE against DENV-2. Conclusion: In summary, ASLE demonstrated the antiviral activity against DENV-2 with less toxicity, and high possibility as a drug candidate. Therefore, it might be suggested for in vivo assessment in the progress of a potent antiviral against DENV-2.
