Abstract Investigating the interplay of factors that result in a viral zoonotic outbreak is difficult, though it is increasingly important. As anthropogenic influences shift the delicate balance of ecosystems, new zoonoses emerge in humans. Sub-Saharan Africa is a notable hotspot for zoonotic disease due to abundant competent mammalian reservoir hosts. Furthermore, poverty, corruption, and an overreliance on natural resources play considerable roles in depleting biological resources, exacerbating the population's susceptibility. Unsurprisingly, viral zoonoses have emerged in Africa, including HIV/AIDS, Ebola, Avian influenza, Lassa fever, Zika, and Monkeypox. These diseases are among the principal causes of death in endemic areas. Though typically distinct in their manifestations, viral zoonoses are connected by underlying, definitive factors. This review summarises vital findings on viral zoonoses in Africa using nine notable case studies as a benchmark for future studies. We discuss the importance of ecological recuperation and protection as a central strategy to control zoonotic diseases. Emphasis was made on moderating key drivers of zoonotic diseases to forestall future pandemics. This is in conjunction with attempts to redirect efforts from reactive to pre-emptive through a multidisciplinary “one health” approach. difficult important ecosystems humans SubSaharan Sub Saharan hosts Furthermore poverty corruption populations population s susceptibility Unsurprisingly HIVAIDS HIV AIDS HIV/AIDS Ebola influenza fever Zika Monkeypox areas manifestations underlying pandemics preemptive pre emptive one health approach

Resumo Investigar a interação de fatores que resultam em um surto zoonótico viral é difícil, embora seja cada vez mais relevante. À medida que as influências antropogênicas mudam o delicado equilíbrio dos ecossistemas, novas zoonoses surgem em humanos. A África Subsaariana é um ponto crítico notável para doenças zoonóticas devido a abundantes reservatórios mamíferos competentes. Além disso, a pobreza, a corrupção e o excesso de confiança nos recursos naturais desempenham papéis consideráveis no esgotamento dos recursos biológicos, exacerbando a suscetibilidade da população. Sem surpresa, zoonoses virais surgiram na África, incluindo HIV/AIDS, Ebola, gripe aviária, febre de lassa, zika e varíola dos macacos. Essas doenças estão entre as principais causas de morte em áreas endêmicas. Apesar de serem tipicamente distintas em suas manifestações, as zoonoses virais estão conectadas por fatores subjacentes e definitivos. Esta revisão resume descobertas vitais sobre zoonoses virais na África usando nove estudos de caso notáveis como referência para estudos futuros. Discutimos a importância da recuperação e proteção ecológica como estratégia central para o controle de doenças zoonóticas.

ABSTRACT Purpose: to investigate the frequency-following response (FFR) for sustained neural activity. Methods: 39 individuals, aged between 20 to 47 months old were divided into 2 groups: (i) 20 individuals without prenatal exposure to the congenital Zika syndrome (CZS) or hydrocephaly, normal development, no risk factors for hearing loss or syndromic hearing impairment and (ii) 19 individuals diagnosed with CZS and microcephaly - based on imaging studies linked to the clinical presentation of the condition. All participants exhibited normal click-ABR tests. FFR waveforms were documented using the /da/ syllable employing the Navigator Pro. The statistical analysis used was ANOVA (p-value <0.05). Results: no distinctions were observed concerning the variables of group, age, or gender with respect to FFR latency values, except for an interaction between gender and group for latency values associated with waves V and F. Children with CZS and microcephaly showed a difference for latency values in wave V for both males and females, when compared to the control group. Conclusion: children presented with CZS and microcephaly showed higher average latencies for waves V, A, C, D and F (male) compared to the control group, whereas, in waves E, F (female) and O they showed higher values in the control group.

ABSTRACT The emergence of insecticide resistance in different mosquito populations underscores the pressing need for alternative approaches to control vector-borne diseases. Among several technological strategies, the employment of bacterial symbionts, such as the Wolbachia pipientis strains wMel and wAlbB to inhibit the ability of Aedes aegypti (Linnaeus, 1762) to transmit dengue and Zika viruses in endemic regions worldwide is promising. This investigation examines both the bacterial diversity associated with Culex quinquefasciatus and the genetic diversity of Wolbachia in females collected in Coari, Amazonas State, Brazil. Both 16S rRNA and Wolbachia surface protein (wsp) gene sequences were generated and examined. Proteobacteria was the dominant phylum. Wolbachia was the predominant genus, followed by Providencia, unclassified Erwiniaceae, and Acinetobacter. The presence of Delftia in Cx. quinquefasciatus need further investigations to identify the strains and if any of them can inhibit the transmission of arboviruses by this mosquito. Wolbachia 16S rRNA sequences were detected in all samples analyzed. The wsp sequences from Coari specimens were identified as Wolbachia wPip strain of the supergroup B. These sequences are identical and share 100% similarity with those of other Cx. quinquefasciatus populations from Brazil. Our findings suggest the hypothesis of previous studies that the Wolbachia invasion in Cx. quinquefasciatus was recent. vectorborne vector borne diseases strategies symbionts Linnaeus, Linnaeus (Linnaeus 1762 promising State Brazil S (wsp examined phylum genus Providencia Erwiniaceae Acinetobacter Cx analyzed B 100 recent 176 10 17 1

ABSTRACT Brazil has been suffering a dengue (DENV) epidemic in 2019 and 2022 and records cases of Zika (ZIKV) and chikungunya (CHIKV). Londrina city, Paraná, stands out for the number of cases and deaths from dengue. Therefore, this study aimed to verify the density and diversity of mosquitoes present in urban public establishments of Londrina, to analyze their ecological relationships, and to investigate the presence of the DENV, ZIKV, and CHIKV. Ovitraps were installed in outdoor sites in two public establishments in each region of Londrina, while adult culicids were caught indoors with a Nasci aspirator. A total of 5077 eggs were obtained in 77 ovitraps. The South region had the highest infestation while the East had the lowest (Ovitrap Positivity Index: 38% and 25%; Egg Density Index: 67.83 and 19.03, respectively). From eggs, 704 Aedes aegypti females and 71 Aedes albopictus females were obtained, while in the aspiration of adults, 99 A. aegypti and 11 Culex quinquefasciatus were captured, the highest number in the West and the lowest in the North. The DENV-II virus was detected in a pool of 17 A. aegypti females in the West region. The results demonstrate high density of pathogen vector species, mainly A. aegypti, in and around establishments, alerting to the need for constant local entomological surveillance to prevent viral circulation, mainly in crowded places. The presence of A. albopictus around the establishments also alerts to the urbanization of the species and potential participation in the viral circulation, demonstrating the need for constant monitoring.

This study presents the synthesis and characterization of five Schiff bases derived from the reaction of 4-(2-aminoethyl)-benzenesulfonamide (compound 1) with corresponding aldehydes, (benzaldehyde, 2-pyridinecarboxaldehyde, 2-quinolinecarboxaldehyde, 8-hydroxy2-quinolinecarboxaldehyde and 4-imidazolecarboxaldehyde, for compounds 2-6, respectively). Characterization was performed by various spectroscopic techniques and supported by density functional theory (DFT) calculations. The crystal structures revealed how the substituent groups influenced the present supramolecular interactions. Compounds 1-4 and 6 showed no cytotoxicity to BHK-21 and VERO E6 cells at the highest concentration of 50 µmol L-1, while compound 5 was cytotoxic at this concentration. Compound 5 was active against the Chikungunya virus at the concentration of 10 µmol L-1, highlighting the effect of the 8-hydroxyquinoline substituent for the antiviral activity. For Zika virus, compound 6 was the only one active at 50 µmol L-1. The results suggest the potential of combining sulfonamides with other chemotypes for further development of antiviral agents, especially in the treatment of arboviral diseases. 42aminoethylbenzenesulfonamide aminoethylbenzenesulfonamide 4 2 aminoethyl benzenesulfonamide 1 aldehydes benzaldehyde, benzaldehyde (benzaldehyde 2pyridinecarboxaldehyde, 2pyridinecarboxaldehyde pyridinecarboxaldehyde pyridinecarboxaldehyde, 2-pyridinecarboxaldehyde 2quinolinecarboxaldehyde, 2quinolinecarboxaldehyde quinolinecarboxaldehyde quinolinecarboxaldehyde, 2-quinolinecarboxaldehyde 8hydroxy2quinolinecarboxaldehyde hydroxyquinolinecarboxaldehyde 8 hydroxy2 hydroxy 4imidazolecarboxaldehyde, 4imidazolecarboxaldehyde imidazolecarboxaldehyde imidazolecarboxaldehyde, 4-imidazolecarboxaldehyde 26, 26 6, 2-6 respectively. respectively . respectively) DFT (DFT calculations interactions 14 1- BHK21 BHK 21 BHK-2 E L1, L1 L 1, L-1 8hydroxyquinoline hydroxyquinoline activity L1. 1. agents diseases 2- BHK2 BHK- L-

ABSTRACT Objective: To detect spatial and spatiotemporal clusters of urban arboviruses and to investigate whether the social development index (SDI) and irregular waste disposal are related to the coefficient of urban arboviruses detection in São Luís, state of Maranhão, Brazil. Methods: The confirmed cases of Dengue, Zika and Chikungunya in São Luís, from 2015 to 2019, were georeferenced to the census tract of residence. The Bayesian Conditional Autoregressive regression model was used to identify the association between SDI and irregular waste disposal sites and the coefficient of urban arboviruses detection. Results: The spatial pattern of arboviruses pointed to the predominance of a low-incidence cluster, except 2016. For the years 2015, 2016, 2017, and 2019, an increase of one unit of waste disposal site increased the coefficient of arboviruses detection in 1.25, 1.09, 1.23, and 1.13 cases of arboviruses per 100 thousand inhabitants, respectively. The SDI was not associated with the coefficient of arboviruses detection. Conclusion: In São Luís, spatiotemporal risk clusters for the occurrence of arboviruses and a positive association between the coefficient of arbovirus detection and sites of irregular waste disposal were identified.

ABSTRACT 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.

Abstract Background: Arboviral diseases are a group of infectious diseases caused by viruses transmitted by arthropods, mainly mosquitoes. These diseases, such as those caused by the dengue (DENV), Zika (ZIKV), chikungunya (CHIKV), and yellow fever (YFV) viruses, have a significant impact worldwide. In this context, entomological surveillance plays a crucial role in the control and prevention of arboviruses by providing essential information on the presence, distribution, and activity of vector mosquitoes. Based on entomological surveillance, transovarian transmission provides information regarding the maintenance and dissemination of arboviruses. The objective of this study was to detect these arboviruses in Goiânia, Goiás, and analyze the occurrence of transovarian transmission. Methods: Aedes aegypti eggs were collected from different regions of Goiânia and cultivated under controlled laboratory conditions until the emergence of adult mosquitoes. Adult females were grouped into pools containing their heads and thoraxes. These pools were subsequently evaluated using reverse-transcription quantitative polymerase chain reaction (RT-qPCR) assay. Results: A total of 157 pools (N=1570) were analyzed, with two pools testing positive for CHIKV and one pool testing positive for ZIKV, indicating that the offspring resulting from transovarian transmission are potentially infectious. Conclusions: In summary, the demonstration of the vertical transmission mechanisms of CHIKV and ZIKV in A. aegypti serves as an alert to health authorities, as these diseases are still underreported, and their primary urban vector has likely acquired this capacity, contributing to the dissemination of these infections.

Zika virus (ZIKV) is a mosquito-borne virus that has emerged as a major public health concern due to its association with severe neurological disorders. In recent years, there has been increasing interest in exploring natural products as potential therapeutics for ZIKV infection. This study aimed to predict the binding affinity of natural compounds to the ZIKV NS2B-NS3 protease (NS2B-NS3pro) using multiple molecular docking algorithms and semiempirical quantum mechanical methods. Our results demonstrate that semiempirical methods can improve the accuracy of molecular docking studies for natural compounds. In this particular case, the PM7 (Parametric Method Number 7) method showed a significant improvement in the coefficient of determination (R2 = 0.85). We expect this combined approach to aid in the development of natural product-based therapies for ZIKV infection and to highlight the importance of continued research in this field.

ABSTRACT Objective: To analyze the factors associated with the individual use of insect repellent by women of childbearing age living in area endemic for arboviruses in Fortaleza, Brazil. Methods: This is a cohort study carried out between 2018 and 2019 with women aged between 15 and 39 years in Fortaleza, state of Ceará, Brazil. A total of 1,173 women users of one of the four selected primary health care units participated in the study. The outcome was divided into: continued use, discontinued use, and nonuse of insect repellent. Crude and adjusted multinominal logistic regression analysis was carried out guided by a hierarchical model, with presentation of the respective odds ratio (OR) and 95% confidence intervals (95%CI). The independent variables include: socioeconomic and demographic data, environmental and sanitary characteristics, knowledge of the insect repellent, and behavioral and pregnancy-related aspects. Results: Only 28% of the participants reported using insect repellent during the two waves of the cohort. Women with higher education (OR=2.55; 95%CI 1.44–4.51); who are employed (OR=1.51; 95%CI 1.12–2.03); who received guidance from healthcare professionals (OR=1.74; 95%CI 1.28–2.36) and the media (OR=1.43; 95%CI 1.01–2.02); who intensified precautions against mosquitoes during the epidemic (OR=3.64; 95%CI 2.29–5.78); and who were pregnant between 2016 and 2019 (OR=2.80; 95%CI 1.83–4.30) had increased odds for continued use of insect repellent. Conclusion: The use of insect repellent among women of childbearing age was associated with a higher level of education, employment, guidance on insect repellent provided by healthcare professionals and the media, behavioral changes to protect against mosquitoes during the Zika virus epidemic, and pregnancy when occurring as of the beginning of the epidemic period.

Mulheres com escolaridade superior (OR=2,55; IC95% 1,44–4,51); com emprego (OR=1,51; IC95% 1,12–2,03); que receberam orientações por profissionais da saúde (OR=1,74; IC95% 1,28–2,36) e pela mídia (OR=1,43; IC95% 1,01–2,02); que intensificaram os cuidados contra o mosquito na epidemia (OR=3,64; IC95% 2,29–5,78); estavam grávidas entre 2016 e 2019 (OR=2,80; IC95% 1,83–4,30) tiveram as chances aumentadas para uso continuado de repelente. Conclusões: O uso de repelente entre mulheres em idade fértil mostrou-se associado a um maior nível de escolaridade, ao emprego, às orientações sobre repelente fornecidas por profissionais de saúde e pela mídia, às mudanças comportamentais de cuidado contra o mosquito durante a epidemia da Zika e à gravidez quando ocorrida a partir do início do período epidêmico.

Abstract The aim of the present study was to compare the oral conditions of children with congenital Zika syndrome (CZS)-associated microcephaly, non-CZS-associated microcephaly, and normotypical children, as well as to characterize their sociodemographic aspects and medical history. A paired cross-sectional study was carried out on 14 children with CZS-associated microcephaly and 24 age-matched controls, in Belo Horizonte, in southeastern Brazil. Children’s oral conditions were assessed: dental caries experience (dmft/DMFT indices); developmental defects of enamel (DDE) index; dental anomalies; mucosal changes; lip sealing, and malocclusion (overjet, overbite, and/or posterior crossbite alterations). The quality of oral hygiene was analyzed by the simplified oral hygiene index. The children’s mothers also answered a questionnaire about sociodemographic and medical history data. The variables were analyzed descriptively. Female participants were more prevalent (60.5%), and the mean age of the participants was 4.9 years (±1.4) (range: 2–8 years) and 92.1% of their exhibited some oral condition. All participants with CZS-associated microcephaly showed absence of lip sealing and had malocclusion (100.0%). When compared to the other groups, children with CZS had a higher percentage of dental anomalies (35.7%), mucosal changes (71.4%), and unsatisfactory oral hygiene (64.3%). In a sample composed mainly of female participants aged less than 5 years, the prevalence of oral conditions and unsatisfactory oral hygiene was higher in the group with CZS-associated microcephaly, followed by the group with non-CZS-associated microcephaly. Normotypical children had the highest percentage of dental caries experience.

The coinfection between malaria (ML) and arboviral diseases represents a major global public health problem, particularly in tropical and subtropical countries. Despite its relevance, this topic is still insufficiently discussed in the current literature. Here, we aimed to investigate the worldwide distribution, symptoms, and diagnosis during coinfection between ML and arboviral diseases. We conducted a systematic review following the Preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement and assessed the selection and eligibility criteria, created and diagrammed maps, and analysed major symptoms with 95% confidence intervals (CI) using prevalence ratio and effect size, also performing latent class analysis. A total of 85,485 studies were retrieved, of which 56 were included: 57.14% in Asia, 25% in Africa, 14.30% in South America, and 3.56% in Europe. A total of 746 individuals were reported to be coinfected with Plasmodium and arbovirus. Concurrent ML, Dengue (DEN), Chikungunya (CHIK), and Zika (ZIK) patients are more likely to present headache and skin rash. Regarding diagnosis, 58,253 were made, of which 38,176 were positive (ML and at least one arboviral disease). The magnitude of these pathogens’ coexistence points out the pressing need for improvements in public health policies towards diagnosis and prevention of both diseases, especially in endemic areas. problem countries relevance literature Here distribution metaanalyses meta analyses PRISMA (PRISMA criteria maps 95 CI (CI size analysis 85485 85 485 85,48 retrieved 5 included 5714 57 14 57.14 Asia 25 Africa 1430 30 14.30 America 356 3 3.56 Europe 74 arbovirus DEN, DEN , (DEN) CHIK, CHIK (CHIK) ZIK (ZIK rash 58253 58 253 58,25 made 38176 38 176 38,17 disease. disease . disease) pathogens areas 9 8548 8 48 85,4 571 1 57.1 2 143 14.3 35 3.5 7 (DEN (CHIK 5825 58,2 3817 17 38,1 854 4 85, 57. 14. 3. 582 58, 381 38,
