“…Most dengue-endemic areas in the Americas have co-circulation of multiple serotypes, which increases the likelihood of concurrent infections [48][49][50] . In fact, the first-ever confirmed case of concurrent DENV infection was reported in Puerto Rico during the 1982 outbreak in a patient infected with DENV-1 and -4 serotypes 49,51 . However, we noted minimal numbers of mixed infections when reviewing serotype data (14 out of 1328, Figure 4), which is significantly lower than those previously reported 48 .…”

Dengue is the most prevalent mosquito-borne viral disease in humans, and cases are continuing to rise globally. In particular, islands in the Caribbean have experienced more frequent outbreaks, and all four dengue virus (DENV) serotypes have been reported in the region, leading to hyperendemicity and increased rates of severe disease. However, there is significant variability regarding virus surveillance and reporting between islands, making it difficult to obtain an accurate understanding of the epidemiological patterns in the Caribbean. To investigate this, we used travel surveillance and genomic epidemiology to reconstruct outbreak dynamics, DENV serotype turnover, and patterns of spread within the region from 2009-2022. We uncovered two recent DENV-3 introductions from Asia, one of which resulted in a large outbreak in Cuba, which was previously under-reported. We also show that while outbreaks can be synchronized between islands, they are often caused by different serotypes. Our study highlights the importance of surveillance of infected travelers to provide a snapshot of local introductions and transmission in areas with limited local surveillance and suggests that the recent DENV-3 introductions may pose a major public health threat in the region.

“…The information obtained has not been disseminated [16]. This is caused by DHF information that has not been updated [17]. In addition, there are obstacles in the form of incomplete data, difficulties in accessing data, not being good at making decisions related to DHF control, and not being informative in presenting DHF data.…”

Background: Dengue fever is still endemic in Indonesia. The government launched a DHF surveillance program. There was found some problems in the surveillance system, and the trend of dengue fever in 2016-2020 which had increased at the Pusat Kesehatan Masyarakat (Puskesmas) of Bantul II. This study aims to evaluate the implementation of DHF surveillance at the Puskesmas Bantul II. Method: This research is an evaluation of the CIPP model (Context, Input, Process, Product) with a qualitative-descriptive approach. This research was conducted in June-July 2021 at the Puskesmas Bantul II. Data was collected by interviewing 5 (five) informants. Results: The implementation of DHF surveillance at the Puskesmas Bantul II is based on input, human resources aren’t skilled epidemiologists, officers still hold concurrent positions, and haven’t received epidemiology/surveillance training. The infrastructure was complete, sufficient, and functioning properly. There is no specific allocation of funds for DHF surveillance. There are SOPs and surveillance guidelines, and DHF activities. Based on the process, the collection, processing, presentation, data analysis, and information dissemination have been carried out. The recommendations haven’t been implemented. The Health Office provides regular feedback, monitoring, and evaluation. Based on the output, reporting once a month on time. But its aren’t complete, some files are missing and damaged. Conclusion: The implementation of DHF surveillance at the Puskesmas Bantul II has been carried out, but several aspects of the input, process, and output do not match the indicators, so it affects the outcomes that are not in accordance with national standards.

“…A person can be infected with the dengue virus several times during their life, either consecutively or simultaneously with two different serotypes. However, for a person who has gotten over dengue fever, a large issue is the occurrence of any subsequent infection with the dengue virus, because it can put a person at high risk for the occurrence of the most severe forms of dengue infection compared to persons not previously infected with the virus [ 15 ]. A special problem in the epidemiology of dengue fever is frequent infection with the dengue virus in pregnant women, whose newborns have antibodies from the mother and are susceptible to dengue hemorrhagic fever if they are infected with one of the other three serotypes [ 16 ].…”

Background and Objectives: Dengue is an important public health concern that warrants an examination of the longer-term global trends of its disease burden. The aim of this study was to assess the trends in dengue incidence and mortality worldwide over the last three decades. Materials and Methods: A descriptive epidemiological study was carried out, investigating the trends in the incidence and mortality of dengue from 1990 to 2019. The dengue incidence and mortality data were obtained from the Global Burden of Disease study database. Trends were examined using joinpoint regression analysis. Results: Globally, there were 56.7 million new cases of dengue reported in 2019: the disease was diagnosed in 27.4 million males and 29.3 million females. A total of 36,055 (18,993 males and 17,032 females) related deaths were reported worldwide in 2019. In both sexes, about 60% of new cases were recorded in the South-East Asia region (16.3 million in males and 17.4 million in females). Globally, the incidence of dengue exhibited an increasing tendency from 1990 to 2019 in both sexes (equally, by 1.2% per year). A significantly decreasing trend in the mortality of dengue was recorded only in females (by −0.5% per year), while an increasing trend was observed in males (by +0.6% per year). Conclusions: The rise in the number of new dengue cases and deaths in the world in the last several decades suggests a need for implementing more effective prevention and management measures.
