Epidemiologists have created a global risks of the spread of Denga fever and predict the growth of the threat of this disease in Europe. Particularly dangerous were the regions in the south of France and northern Italy, where the favorable climate allows the tiger mosquitoes to multiply quickly, which are carriers of the virus.
Tiger mosquitoes, which have already spread to Europe, are not a significant threat to Ukraine because of the temperate climate, become dangerous in other parts of the continent. According to the new model presented in the journal Nature Communications , epidemiologists have taken into account the factors that affect the behavior of mosquitoes: insects that develop in optimal conditions, live longer and carry a greater risk of disease spread.
From 2000 to 2022, the number of Denge fever has increased sharply - from 500 thousand to 4.2 million . This was the reasons for global changes, including climatic changes and active migration processes . In the new prediction model, scientists also took into account the impact of the environment on the ability of mosquitoes to carry the virus. This enables medical institutions to respond in time to possible outbreaks and reduce the risks of infection.
Deng is already spreading in Europe. For example, in the south of France, a 44-year-old British tourist became infected with Denge virus without leaving the country. She also transmitted the infection to her loved ones, which indicates the intra -European spread of the disease.
Fiji uses drones to control the populations of dengue mosquitoes that spray mosquitoes infected with bacteria that prevent their reproduction. This approach has reduced the number of hazardous insects and can be used in other regions.
