Chikungunya, an arboviral disease transmitted by Aedes mosquitoes, has recently increased dramatically in incidence and geographic extent. Large outbreaks have affected islands of the Indian Ocean, India and other parts of South and Southeast Asia, Africa and most recently Italy. International travellers have disseminated new strains of the virus, some into regions from which chikungunya has hitherto been absent. In parallel, over the past 30 years international trade has resulted in the spread of A. albopictus from its original range in Asia, to all continents but Antarctica, thereby extending the geographic area over which transmission can occur.

Introduction of Vector-Borne Infections in Europe: Emerging and Re-Emerging Viral Pathogens with Potential Impact on One Health.

The rise and resurgence of vector-borne diseases (VBDs) in Europe pose an expanding public health challenge, exacerbated by climate change, globalization, and ecological disruptions. Both arthropod-borne viruses (arboviruses) transmitted by ticks such as Crimean-Congo hemorrhagic fever and arboviruses transmitted by mosquitoes like dengue, Chikungunya, Zika, and Japanese encephalitis have broadened their distribution due to rising temperatures, changes in rainfall, and increased human mobility. By emphasizing the importance of interconnected human, animal, and environmental health, integrated One Health strategies are crucial in addressing this complex issue.

Background: Brazil is considered an epicenter for emerging and re-emerging arboviruses that significantly impact public health. The mid-sized city of São José do Rio Preto (SJdRP) in northwestern São Paulo state is considered hyperendemic for arboviral diseases, with case numbers climbing each year. Only 45 cases of chikungunya (CHIKV) were reported in the city from 2015 to 2022, indicating cryptic circulation of this virus, but cases in the state increased notably in 2023.

Background: Climate change significantly influences the distribution and severity of tropical diseases. Rising temperatures, changing precipitation patterns, and extreme weather events are transforming the habitats of vectors like mosquitoes and ticks, promoting their proliferation and geographic spread. These changes have facilitated the resurgence of diseases such as malaria, dengue, and chikungunya fever in previously unaffected areas, including parts of Europe and Italy.

Article Synopsis
- Tropical regions have a hot, humid climate that can lead to outbreaks of viral infections, which can range from mild symptoms to severe complications.
- Emerging viral infections are often associated with various eye conditions, particularly in individuals from or returning to endemic areas.
- Diagnosis is confirmed through advanced testing methods, while treatment mainly focuses on supportive care, with corticosteroids used for eye inflammation; most patients have a good chance of recovery, but some may suffer lasting vision issues.
