“…Other factors, such as intensification of agriculture, livestock farming, mining, and the installation of large hydroelectric dams, are known to increase deforestation and are associated with human mobility and density. These factors change the ecological patterns of virus-vector-host interactions and result in a scenario that is totally favorable to the spread of diseases such as dengue, Zika, and chikungunya 41 , 42 .…”

Background: The riverine communities of the Amazon comprise different social groups that inhabit the rural areas on the banks of rivers and lakes. Residents usually travel by river to rural and urban areas and are then exposed to urbanized diseases such as those caused by arbovirus infection. In Brazil, emerging diseases such as dengue, Zika, chikungunya, and those caused by infection with Oropouche and Mayaro viruses necessitate epidemiological surveillance. This study was aimed at determining the frequency of positivity for immunoglobulin (Ig)G and IgM antibodies against Zika, chikungunya, and dengue viruses and performing molecular analyses to detect viral RNA for the Zika, chikungunya, dengue virus, Oropouche, and Mayaro viruses, in the same serum samples obtained from riverside populations. Methods: This cross-sectional study was conducted in a riverside population in the Humaitá municipality of the Brazilian Amazon. More than 80% of the local population participated in this study. Entomological samples were collected to identify local mosquito vectors. Results: Analysis of 205 human serological samples revealed IgG antibodies against the dengue virus in 85 individuals. No molecular positivity was observed in human samples. Entomological analyses revealed 3,187 Diptera species, with Mansonia being the most frequent genus. Aedes aegypti and Aedes albopictus were not detected in the two collections. Conclusions: IgG antibodies against the dengue virus were highly prevalent, suggesting previous exposure. The absence of the arbovirus vectors Aedes aegypti and Aedes albopictus in the samples supports the hypothesis that the infections recorded likely occurred outside the riverside communities investigated.

“…From this scenario, it is worth mentioning that the data found in the study, especially in relation to the immunogen against yellow fever, point to an imminent outbreak of the disease in the state. Bearing in mind that Maranhão comprises an enzootic area of yellow fever in Brazil, that is, they are regions where the disease is naturally maintained in a constant cycle of transmission, due to the existence of primary hosts linked to characteristics of the Amazon biome (Costa et al, 2005., Gomes et al, 2023. Thus, in accordance with the Brazilian children's immunization schedule, it is necessary for children to be vaccinated at 9 months, especially those living in endemic regions of the disease.…”

Active immunization through vaccination is the most effective method to reduce the spread of infectious and contagious diseases. Thus, this study analyzed the vaccination rates in the state of Maranhão in the period 2013–2022, in order to understand the implications of reducing this coverage for the reemergence of diseases that had been eradicated until then and the main outcomes. This is an analytical research of the ecological type of time series carried out in the state of Maranhão. (BCG), human rotavirus vaccine, pneumococcal vaccine 10, pentavalent vaccine (DTP + Hib + HB), meningococcal C vaccine, polio vaccine, and yellow fever (YF) vaccine. in the 19 regional health units of the state (URS). Of the seven immunobiologicals studied, the only ones to reach the recommended target for vaccination coverage were BCG and poliomyelitis, during the period of data analysis. Regarding the trend, none showed an increasing pattern during the analyzed period. Undoubtedly, vaccines are indispensable tools for preventing and combating diseases, in addition to being extremely cost-effective. In view of the results, it can be said that the population is certainly the main protagonist in this scenario, since the success or failure of immunization actions are closely associated with society's adherence. Therefore, supporting and encouraging actions that contribute to community awareness and access to vaccines are fundamental in this context.

“…A maioria das doenças infecciosas emergentes são de origem zoonótica. A necessidade de uma visão mais ampla do conceito de saúde em que enfatize uma abordagem integrada e unificadora que vise equilibrar e otimizar de forma sustentável a saúde de pessoas, animais e ecossistemas torna-se cada vez mais contundente uma vez que novos casos de doenças negligenciadas de origem animal são confirmados (TOUSEEF et al, 2023;GOMES et al, 2023).…”
