| dengue vaccines: recent developments, ongoing challenges and current candidates. | dengue is among the most prevalent and important arbovirus diseases of humans. to effectively control this rapidly spreading disease, control of the vector mosquito and a safe and efficacious vaccine are critical. despite considerable efforts, the development of a successful vaccine has remained elusive. multiple factors have complicated the creation of a successful vaccine, not the least of which are the complex, immune-mediated responses against four antigenically distinct serotypes necessitat ... | 0 | 23984962 |
| aedes taeniorhynchus vectorial capacity informs a pre-emptive assessment of west nile virus establishment in galápagos. | increased connectivity with the mainland has led to the arrival of many invasive species to the galápagos islands, including novel pathogens, threatening the archipelago's unique fauna. here we consider the potential role of the mosquito aedes taeniorhynchus in maintaining the flavivirus west nile virus [wnv] should it reach the islands. we report on three components of vectorial capacity - vector competency, distributional abundance and host-feeding. in contrast to usa strains, galápagos a. tae ... | 0 | 23519190 |

| dengue: challenges for policy makers and vaccine developers. | because of the increasing incidence, geographic expansion and economic burden of dengue transmission, dengue poses major challenges to policy makers. a vaccine against dengue is urgently needed, but vaccine development has been hampered by the lack of an appropriate animal model, poor understanding of correlates of successful human immunity, the fear of immune enhancement, and viral interference in tetravalent combinations. the most suitable target epitopes for vaccines, as well as the role of n ... | 0 | 24781826 |
| molecular detection and typing of dengue viruses from archived tissues of fatal cases by rt-pcr and sequencing: diagnostic and epidemiologic implications. | diagnosis of dengue virus (denv) infection in fatal cases is challenging because of the frequent unavailability of blood or fresh tissues. for formalin-fixed, paraffin-embedded (ffpe) tissues immunohistochemistry (ihc) can be used; however, it may not be as sensitive and serotyping is not possible. the application of reverse transcription-polymerase chain reaction (rt-pcr) for the detection of denv in ffpe tissues has been very limited. we evaluated ffpe autopsy tissues of 122 patients with susp ... | 0 | 22302871 |

| the tortoise or the hare? impacts of within-host dynamics on transmission success of arthropod-borne viruses. | arthropod-borne viruses (arboviruses) are maintained in a cycle of alternating transmission between vertebrate hosts and arthropod vectors. arboviruses possess rna genomes capable of rapid diversification and adaptation, and the between-host trade-offs inherent to host alternation impose well-documented constraints on arbovirus evolution. here, we investigate the less well-studied within-host trade-offs that shape arbovirus replication dynamics and transmission. arboviruses generally establish l ... | 0 | 26150665 |
| assessment of arbovirus surveillance 13 years after introduction of west nile virus, united states. | before 1999, the united states had no appropriated funding for arboviral surveillance, and many states conducted no such surveillance. after emergence of west nile virus (wnv), federal funding was distributed to state and selected local health departments to build wnv surveillance systems. the council of state and territorial epidemiologists conducted assessments of surveillance capacity of resulting systems in 2004 and in 2012; the assessment in 2012 was conducted after a 61% decrease in federa ... | 0 | 26079471 |
