Arthropod-borne viruses (arboviruses) are transmitted by arthropod vectors to humans, leading disease outbreaks mainly in tropical regions of the world.1Weaver SC Charlier C Vasilakis N Lecuit M Zika, chikungunya, and other emerging vector-borne viral diseases.Annu Rev Med. 2018; 69: 395-408Crossref PubMed Scopus (234) Google Scholar Although many arboviruses known, three Aedes-spp-borne particularly concerning for humans at a global scale due recurring large expanding epidemic dengue virus,...
Abstract Background Understanding the impact of burden COVID-19 is key to successfully navigating pandemic. As part a larger investigation on mortality impact, this study aims estimate Potential Years Life Lost (PYLL) in 17 countries and territories across world (Australia, Brazil, Cape Verde, Colombia, Cyprus, France, Georgia, Israel, Kazakhstan, Peru, Norway, England & Wales, Scotland, Slovenia, Sweden, Ukraine, United States [USA]). Methods Age- sex-specific death numbers from primary...
Background Cabo Verde, an island country in West Africa, has been affected since human colonization by epidemics of vector-borne diseases with major dengue and zika recent years. Although there is a national program for integrated vector control, innovative strategies that reinforce routine activities strengthen control are necessary to prevent the emergence or reemergence arboviruses new zika. Insecticide paints evidenced as technologies formulation insecticides more residual safe way. The...
Abstract Surveillance of malaria vector species and the monitoring insecticide resistance are essential to inform control strategies support reduction infections disease. Genetic barcoding mosquitoes is a useful tool assist high-throughput surveillance resistance, discriminate between sibling detect presence Plasmodium infections. In this study, we combined multiplex PCR, custom designed dual indexing, Illumina next generation sequencing for high throughput single nucleotide polymorphism...
Dengue is an arboviral disease caused by dengue virus (DENV), whose main vectors are the mosquitoes Aedes aegypti and albopictus. A. only DENV vector in Cape Verde, African country that suffered its first outbreak of 2009. However, little known about variation level competence this mosquito population to different serotypes. This study aimed evaluate from island Santiago, four serotypes detect vertical transmission. Mosquitoes were fed on blood containing dissected at 7, 14 21 days...
Abstract Background Aedes spp. are responsible for the transmission of many arboviruses, which contribute to rising human morbidity and mortality worldwide. The aegypti mosquito is a main vector chikungunya, dengue yellow fever infections, whose incidence have been increasing distribution expanding. This has also driven emergence Zika virus (ZIKV), first reported in Africa spread rapidly Asia more recently across Americas. During outbreak Americas, Cape Verde became African country declaring...
Abstract Background Due to the lack of vaccines, malaria control mainly involves anopheline vectors ( Anopheles spp.) using chemical insecticides. However, prolonged and indiscriminate use these compounds has led emergence resistance in populations Africa. Insecticide surveillance programs are less frequent Cabo Verde than other African countries. This study aimed investigate circulation L1014F L1014S alleles natural arabiensis collected from two sampling sites city Praia, Verde. Methods...
Aedes mosquito vectors transmit many viruses of global health concern, including dengue, chikungunya and Zika. These vector-borne viral diseases have a limited number treatment options, vaccines vary in their effectiveness. Consequently, integrated vector management is primary strategy for disease control. However, the increasing emergence spread insecticide resistance threatening efficacy control methods. Identifying mutations associated with populations important to monitor occurrence...
Many vector-borne diseases circulate in the Republic of Cabo Verde. These include malaria during colonization archipelago by Portuguese explorers and several arboviruses such as yellow fever (now eradicated), dengue zika. To control these diseases, an integrated vector program was implemented. The main targeted mosquito vectors are Aedes aegypti Anopheles arabiensis, a lesser extent potential arbovirus Culex pipiens s.l. strategy is focused on aquatic stages using diesel oil Temephos. This...
Mosquitoes of the Anopheles gambiae complex are main malaria vectors worldwide. Due to lack a vaccine prevent malaria, principal way reduce impact this disease relies on use chemical insecticides control its vectors. However, intensive such compounds has led emergence insecticide resistance in several populations Africa. This study aimed investigate presence alleles an arabiensis population from City Praia, capital Archipelago Cabo Verde, one countries World Health Organization list that...
Abstract In November 2015, cases of Zika virus infection were recorded in Cabo Verde (Africa), originating from Brazil. The outbreak subsided after seven months with 7580 suspected cases. We performed a serological survey (n = 431) Praia, the capital city, 3 transmission ceased. Serum samples screened for arbovirus antibodies using ELISA techniques and revealed seroconverted individuals (10.9%), dengue (1–4) (12.5%), yellow fever (0.2%) chikungunya (2.6%) infections. seropositivity was...
Abstract Mosquitoes of the genus Aedes are main vectors many viruses, e.g. dengue and Zika, which affect millions people each year for there limited treatment options. Understanding how mosquitoes tolerate high viral loads may lead to better disease control strategies. Elucidating endogenous elements (EVEs) within vector genomes give exploitable biological insights. Previous studies have reported presence a large number EVEs in genomes. Here we investigated if flavivirus conserved across...
Background Antimalarial antibody measurements are useful because they reflect historical and recent exposure to malaria. As such, may provide additional information assess ongoing transmission in low endemic or pre-elimination settings where cases rare. In addition, the absence of responses certain individuals can indicate cessation transmission. Commercial malaria enzyme-linked immunosorbent assays (ELISA) detect antimalarial antibodies commonly used screen blood donations for possible...
Background: The pandemic caused by SARS-CoV-2 (Severe Acute Respiratory Syndrome CoronaVirus 2), the etiological agent of COVID-19, affected, until July 15, 2020, more than fourteen million people and six hundred thousand deaths in world, constituting a worldwide public health concern, especially small island states. In Cape Verde, first confirmed case infection was recorded on Boa Vista March 19, 2020. Since then, has spread to several islands, July, only two nine inhabited islands had not...
Arthropod-borne viruses, such as Dengue (DENV), Chikungunya (CHIKV), and Zika (ZIKV), pose a challenge to public health, due their worldwide distribution large-scale outbreaks. fever is currently one of the most important diseases it caused by four serotypes DENV mainly transmitted mosquito Aedes aegypti. It estimated that 50-100 million cases are reported every year worldwide. More recently, CHIKV ZIKV, which also Ae. aegypti, have epidemics in countries Caribbean region, Pacific Americas....

Abstract BackgroundDue to the lack of vaccines, malaria control mainly involves incriminated vector, Anopheles spp, using chemical insecticides. However, prolonged and indiscriminate use these compounds has led emergence resistance in populations from African continent. The surveillance this is more frequent other countries; however, Cabo Verde does not carry out same way. Thus, study aimed investigate circulation L1014F L1014S alleles natural arabiensis city Praia, Verde. MethodsLarvae...
