Subsequently, WNV was identified in the rest of the old-world and from 1999 in North America. Birds are the primary hosts, and WNV is maintained in a bird-mosquito-bird cycle, with pigs as amplifying hosts and humans and horses as incidental hosts. WNV transmission is warranted by mosquitoes, usually of the <i>Culex</i> spp., with a tendency to spill over when mosquitoes' populations build up. Other types of transmissions have been described in endemic areas, as trough transplanted organs and transfused blood, placenta, maternal milk, and in some occupational settings. WNV infections in North America and Europe are generally reported during the summer and autumn. Extreme climate phenomena and soil degradation are important events which contribute to expansion of mosquito population and consequently to the increasing number of infections. Draught plays a pivotal role as it makes foul water standing in city drains and catch basins richer of organic material. The relationship between global warming and WNV in climate areas is depicted by investigations on 16,298 WNV cases observed in the United States during the period 2001-2005 that showed that a 5°C increase in mean maximum weekly temperature was associated with a 32-50% higher incidence of WNV infection. In Europe, during the 2022 season, an increase of WNV cases was observed in Mediterranean countries where 1,041 cases were reported based on ECDC data. This outbreak can be associated to the climate characteristics reported during this period and to the introduction of a new WNV-1 lineage.

Among the objectives of sustainable development is the control of infectious diseases; therefore, it is necessary to evaluate the impact of existing programs on the prevention and management of infectious diseases. The aim of this study was to analyze the epidemiological, clinical, and geospatial behavior of dengue in children in a region of the Colombian Caribbean. A retrospective cross-sectional study was carried out. The data provided by the Municipal Health Secretariat were taken and the cases of dengue and severe dengue in children aged 0 to 17 years reported in Sincelejo, Colombia, were extracted. The sociodemographic and clinical characteristics presented were analyzed and descriptive statistics were performed with tables and graphs of frequency and accumulated percentages. To locate the areas with the highest incidence of cases during the year, a geospatial location of the cases was carried out with the QGIS v.3.8 program. In 2019, there were 3611 cases of dengue fever in children aged 0 to 17 years. There were 1394 (38.6%) cases with warning signs, and 41 (1.1%) cases of severe dengue fever. Cases of severe dengue fever occurred more frequently in women. The incidence rate found was 3927 and 45.1 cases per 100,000 population, for dengue and severe dengue in children, respectively. The age ranges with the highest number of cases were children aged 4 to 9 years with 1778 cases. The clinical presentation was varied, with the most frequent symptoms, in all groups, being fever in 100% of cases, myalgias ≥71%, and arthralgias ≥64%. Only 9% (n=315) of the cases, corresponded to cases in the rural area.
