“…Dengue fever spreads via "virus-mosquito-human" transmission. Current preventive strategies focus on the mosquito itself, with a particular focus on environmental rectification and maintenance (e.g., targeting sites of mosquito breeding) [23,24]. The large-scale outbreaks of dengue fever that occurred in Kaohsiung City between 2014 and 2015, which were likely the result of imported cases of dengue, showed the limitations of this vector-focused approach.…”

Background: Dengue is endemic in over 100 countries and is an important public health problem worldwide. Dengue fever is not endemic in Taiwan; the importation of dengue viruses from neighboring countries via close commercial links and air travel is considered to be the cause of local outbreaks. Therefore, efforts toward disease control have focused on preventing the importation of dengue into Taiwan. In this study, we investigated the relationships between the numbers of imported and indigenous dengue cases to test the validity of this strategy. Methods: Data on cases of dengue fever that occurred between 2013 and 2018 were obtained from the surveillance systems of the Taiwan Center for Disease Control and Kaohsiung City Health Department. Standard epidemiological data, including the monthly numbers of indigenous and imported cases of dengue, were calculated. Potential associations between the numbers of indigenous and imported cases were investigated using correlation analyses. Results: We identified a possible relationship between the period of disease concealment and the number of imported dengue cases, which resulted in epidemics of indigenous dengue fever within local communities. Further analysis of confirmed cases during previous epidemics in Kaohsiung City found that the risk of indigenous dengue fever may be related to the likelihood that patients with imported dengue fever will stay within local communities. Conclusion: Given the correlations found between imported and indigenous cases of dengue fever, as well as the relationship between the disease concealment period and the risk of indigenous dengue fever, prevention of disease importation and efficient identification of dengue cases within high-risk communities remain the major priorities for disease control.

Background. Dengue is endemic in over 100 countries and is an important public health problem worldwide. Dengue is not considered endemic in Taiwan however, with importation of dengue viruses from neighboring countries via close commercial links and air travel believed to be the cause of local outbreaks. Disease control efforts have therefore focused on preventing the importation of dengue into Taiwan. Here, we investigate the relationships between numbers of imported and indigenous dengue cases to test the validity of this strategy. Methods. Dengue-fever case data from between 2013 and 2018 was obtained from the surveillance systems of the Taiwan Center for Disease Control and Kaohsiung City Health department. Standard epidemiological data, including the monthly numbers of indigenous and imported dengue cases, was calculated. Potential associations between the number of indigenous and imported cases were investigated using correlation analyses. Results. We identified a possible relationship between the period of disease concealment and the number of reported imported dengue cases which resulted in indigenous dengue-fever epidemics within local communities. Further analysis of confirmed dengue cases during previous dengue-fever epidemics in Kaohsiung City found that the risk of indigenous dengue-fever may be related to the likelihood of patients suffering from imported cases of dengue-fever staying within local communities. Conclusion. Given the correlations found between imported and indigenous dengue-fever cases, as well as the relationship between disease concealment period and risk of indigenous dengue-fever, the major priorities for disease control remain prevention of disease importation and efficient identification of dengue cases within high-risk communities.

“…It should be noted, however, that the Ross-Macdonald model was not formulated to specifically explore larval mosquito control. Recent quantitative assessments indicate that, under certain circumstances, control of the larvae may lead to greater than expected reductions in the transmission of pathogens [77]. In the context of larval control of Aedes aegypti, there should be the large-scale elimination of potential hatcheries.…”

Coastal El Niño is a weather phenomenon that is caused by abnormal warming (above 0.4°C) of the Pacific Ocean waters near the coasts of Ecuador and Peru, and it can even reach the central and southern Peruvian coast. As a result of the climatic phenomenon, the Aedes aegypti vector (which in turn is a vector of chikungunya and Zika fever) had been quickly installed in 448 districts of Peru, and emergency was declared in 10 regions, which reported 231,874 victims; 1,129,013 affected and 143 dead. It is necessary to know this, because the direct impact of the weather phenomena contributes to the dengue vector conditioning, facilitating its dissemination with ease. The geographical and climatic conditions of the cities most affected by the El Niño Costero phenomenon turned them into zones of epidemics; in these places, there is an important population growth, from urbanization to sectorization in young towns and urban slums, where in many there is no basic infrastructure and water supply is insufficient, which requires temporary water storage, as well as high temperatures, migratory movement, and beaches with influx of people, which make not only dengue proliferate but also other arbovirosis such as chikungunya.
