Special Issue Information

Dear Colleagues,

Emerging arboviruses pose a growing threat to global public health, as their geographic range and incidence are expanding rapidly due to climate change, urbanization, and increased human mobility. In recent years, viruses such as Zika, chikungunya, dengue, Oropouche, and yellow fever have re-emerged or spread into new regions, highlighting the urgent need for improved surveillance, prevention, and response strategies. This Special Issue, “Emerging Arboviruses: Epidemiology, Control and Future Directions”, brings together cutting-edge research and expert perspectives on the evolving epidemiology of arboviral diseases, innovative control measures, and predictive tools for outbreak preparedness. By addressing the multidisciplinary challenges involved in arbovirus emergence—from vector ecology to vaccine development—this collection aims to inform policy, guide public health action, and identify critical gaps in our understanding of these complex pathogens.

The Oropouche virus (OROV) has been circulating in the Amazon region since the 1960s, with a progressive increase in outbreaks and human cases reported in Brazil and neighboring countries. In the Rio de Janeiro state, there has been a significant rise in suspected cases of arboviruses, with only 30% of laboratory tests confirming infections with dengue, Zika, or chikungunya viruses. The investigation of OROV virus circulation in the Rio de Janeiro state was initiated and confirmed in April 2024. Our study aimed to retrospectively investigate OROV infections in dengue-suspected cases with inconclusive diagnosis in order to better understand the temporal and geographic introduction of OROV in the Rio de Janeiro state. Municipalities from Rio de Janeiro with arbovirus-like fever cases but a low percentage of dengue-positive RT-PCR test confirmations were identified in the laboratory database. Samples were selected for testing OROV infections using real-time RT-PCR as recommended by the Brazilian Ministry of Health. Municipalities in the Middle Paraíba region of the state showed 93% negative tests results for dengue, Zika, and chikungunya starting in September 2023. A total of 118 positive cases of Oropouche were recorded in the state of Rio de Janeiro between March and July 2024. Moreover, by genome sequencing of eight strains, it was shown that OROV circulating in Rio de Janeiro belongs to recently emergent M1L2S2 lineage. Our findings retrospectively revealed a concentration of cases in the Middle Paraíba region and an outbreak in the rural village of Cacaria, located in the municipality of Piraí. According to our data, this region is the first area with sustained transmission in the Rio de Janeiro state. Full article
