“…This contributes to information exposure, literacy levels, and community participation in efforts to control arboviral vectors. A similar phenomenon was reported in Peru, where community knowledge about dengue was influenced by demographic characteristics, especially women of mature and married age, and middle to high education, but not by rurality (30). Similar findings were reported in Laos and Thailand in 2011 and 2013, where dengue vector infestation was higher in suburban areas where the socio-demographic population was more economically valuable than in rural areas (19).…”

Introduction: The population density of Aedes mosquitoes is a risk factor for dengue in endemic areas. Therefore, it is necessary to understand the risk factors for mosquito vector emergence in settlements. This study aimed to determine the key factors associated with the occurrence and population density of dengue vectors in peri-urban and rural settlements. Methods: A cross-sectional study was conducted in two dengue-endemic villages, Bergas-Kidul and Gebugan, representing peri-urban and rural settlements, respectively. A cluster-based larval survey was conducted in the dengue-case house and in 18–20 houses around a radius of 100 m. All water containers and their characteristics and mosquito larvae emergence were recorded in each house to calculate Aedes indices. The geographic coordinates, altitude, air temperature, and humidity were mapped and analyzed using GIS and SPSS software. Results and Discussion: Dengue vectors were found in peri-urban and rural with HI, CI, BI, and DF indices of 29.3%, 32.2%, 35.4, 6.0; then 12.2%, 14.3%, 14.6, and 3.0, respectively. In peri-urban areas, larval occurrence was associated with air temperature, air humidity, container type, and open microhabitat, whereas in rural areas, it was associated with only open microhabitat. Conclusion: The Aedes indices represent a high density of mosquito populations, and the existence of open microhabitats is the key factor for larval occurrence in both peri-urban and rural settlements. Community participation in vector control needs to be increased in addition to studying the resistance of Aedes mosquitoes to a number of insecticide groups.

“…This implies that once the diagnosis was made, those who self-medicated with these drugs died faster than those who did not selfmedicate. A possible explanation of this phenomena is found in the growing tendency of selfmedicating in Peru which could negatively affect the clinical course of diseases such as dengue when anti-inflammatories and fever-reducers are used without a medical prescription which could trigger or worsen the hemorrhagic manifestations and lead to hypovolemic shock [30][31][32] . Almost all deceased presented warning signs during the initial assessment, despite that, dengue was not suspected in an important fraction of patients.…”

OBJECTIVE: To perform a dengue-related death time analysis that occurred in Piura and Ica (Peru) during the atmospheric phenomena of El Nino Costero and Cyclone Yaku in 2023. MATERIAL AND METHODS: A case-series study was performed. We included the deaths between January 1 and June 3, 2023. We reviewed the research data base of the deaths as well as the clinical epidemiology records, death certificates and laboratory test results. A time analysis was performed from the date of onset of symptoms, date of first visit at a health establishment, date that dengue diagnosis was first registered and date of death. RESULTS: We included 40 deaths by dengue in the study. 70% were females, the median age of death was 51 years of age, and 70% came from Piura. 51.2% presented some comorbidity and 14% had self-medicated with metamizole, other NSAIDS or corticoids before the initial medical consultation. 37.5% presented an unconventional clinical pattern at admission and dengue was not suspected in 40% during the initial assessment. The median time until the initial assessment, the diagnosis time, and the time from diagnosis until death were 3 days, 0 days, and 1 day, respectively. Adults presented a time until the initial assessment significantly greater than the other age groups (p=0.048), the diagnosis time was significantly less than those seen at the Health Department establishments and regional government establishments (MINSA/GORE) than in private establishments (p=0.014) and greater in pediatrics (p=0.018). The time from diagnosis until death was significantly less in those that self-medicated before the initial assessment (p=0.041). CONCLUSION: The adults presented a significantly greater time until the initial assessment; the diagnosis time was less than those seen in MINSA/GORE establishments and greater in pediatrics, furthermore, the time from diagnosis until death was significantly less in those who self-medicated before the initial assessment. An important fraction of deaths presented comorbidities and an unconventional clinical pattern at admission, with dengue frequently not suspected during the initial assessment.

“…However, there are no studies assessing the knowledge level of dengue fever in the currently 2023 outbreak in Peru. For this reason, it is crucial to conduct studies in order to provide evidence-based information to bridge gaps and serve as a milestone for policy makers (Taylor, 2023), aiming to enhance the diagnosis, management, prevention and control for future outbreaks (Fernandez-Guzman et al, 2023). The objective of this study was to evaluate the knowledge level and perception of dengue fever regarding the diagnosis, management, and prevention of this disease among Peruvian physicians and to determine the factors associated with higher knowledge.…”

Objective To evaluate the knowledge level and perception of dengue fever regarding the diagnosis, management, and prevention of this disease among Peruvian physicians and to determine the factors associated with higher knowledge. Methodology: We conducted an analytical cross-sectional study based on an online survey from June 21, 2023, to July 20, 2023. Licensed physicians who live and practice Medicine in Peru were included. To evaluate the factors associated with a high level of knowledge (≥ 70% of correct answer), we used crude (cPR) and adjusted (aPR) prevalence ratios with 95% confidence intervals (95%CI) using a Poisson regression model. Results Overall, 359 participants (median age, 33 years; male, 56.5%) were included. 78.8% of participants achieved ≥ 70% of correct answers in the questionnaire. In the multivariable analysis, factors associated with high level of knowledge (≥ 70%) included having read the Peruvian clinical practice guidelines for dengue management (aPR: 1.29; 95% CI: 1.12 to 1.49), having experience in treating patients with dengue (aPR: 1.32; 95% CI: 1.03 to 1.68), and having treated cases of dengue frequently (aPR: 1.22; 95% CI: 1.02 to 1.46). Finally, physicians who held a clear opinion about whether the Peruvian Ministry of Health adequately trained healthcare personnel, whether in agreement (aPR: 1.23; 95% CI: 1.05 to 1.44) or disagreement (aPR: 1.20; 95% CI: 1.04 to 1.38), demonstrated higher knowledge about dengue compared to those who had a neutral opinion (neither agreed nor disagreed). Conclusions There was a high level of knowledge about dengue fever among Peruvian physicians; however, given the lower knowledge in the Eastern macroregion, educational campaigns would be necessary in this area to improve the identification and treatment of cases. Our study also showed that having clinical experience in the management of dengue is associated with higher knowledge.
