The Dengue alert is growing not only in tropical regions but also in Italy, as the Ministry of Health has published a new circular to inform the Regions about the need for increased prevention and surveillance against the indigenous transmission of the virus through the tiger mosquito. Brazil and Argentina are currently grappling with record infections, highlighting the global concern surrounding this mosquito-borne disease.
Dengue is a viral disease transmitted by mosquitoes infected with the Dengue virus, with four different serotypes. It is widespread in tropical and subtropical regions and can cause epidemic outbreaks even in continental Europe. Currently, approximately half of the world‘s population is at risk of Dengue, with an estimated 100-400 million infections per year.
The Ministry of Health in Italy has issued a new circular addressing the global increase in Dengue cases and preparing for the upcoming vector season. Regions are urged to enhance surveillance of human cases, implement environmental remediation measures, and identify potential sites at risk for invasive mosquitoes. Correct communication and awareness among healthcare workers and the public are also emphasized in the circular.
Experts believe that the next pandemic could be caused by mosquitoes, with warmer temperatures and changing rainfall patterns creating more favorable conditions for disease-carrying insects in Europe. Factors such as climate change, travel and tourism, urbanization, and wildlife contribute to the prevalence of infectious diseases spread by mosquitoes.
In Europe, the number of Dengue cases is increasing, with a surge recorded in France and Italy. While the European Union’s share of Dengue cases is still minimal compared to global numbers, the disease could become endemic in southern Europe in the coming years. Brazil and Argentina are currently facing serious epidemics of Dengue, with millions of cases reported and vaccination campaigns implemented to combat the spread of the virus.
The global concern surrounding the Dengue virus highlights the importance of effective prevention and surveillance measures to control the spread of the disease, both in tropical regions and now also in countries like Italy. As the world grapples with the impact of mosquito-borne diseases, it is crucial for governments and healthcare authorities to prioritize efforts to combat these potentially deadly viruses.
