Nevertheless, depending on the geographical location, and immunization history of the patient, most of these cross-reactive flaviviruses can readily be ruled out. The surprisingly broad spectrum of ecological conditions occupied by tick-borne flaviviruses is worthy of further comment. This higher seroprevalence may reflect in part, an increase in flavivirus transmission between the two study periods. Phylogenetic relationships of flaviviruses correlate with their epidemiology, disease association and biogeography. These false alerts corresponded to viral epidemics not caused by a flavivirus. However, covering these containers had a negligible effect on the flavivirus seroprevalence in the study population. 75 different flaviviruses have been identified, roughly half of which are capable of causing disease in humans. Evolution, epidemiology and dispersal of flaviviruses revealed by molecular phylogenies. This study assesses associations between sociodemographic factors and flavivirus seroprevalence in this region. These associations may have been affected by the time of exposure of the subjects to the factors relative to their infection with a flavivirus. The ongoing identification of attachment and entry receptors for flaviviruses will undoubtedly impact our understanding of antibody neutralisation. Ticks are potential reservoirs of at least two mosquito-borne flaviviruses. However, a negative result is suggestive of dengue, given that it is difficult to confirm flavivirus infection in practice. Cellular factors that play a required role as a flavivirus 'receptor' have not yet been rigorously defined despite considerable effort. Most flaviviruses (at least 50 species) are transmitted to vertebrate hosts by mosquitoes. The development of vaccines for several flaviviruses is being actively pursued with the goal of eliciting protective levels of neutralising antibody. These results clearly show the importance of animal disease and mortality surveillance in the context of emerging flavivirus diseases. Vaccines that elicit potently neutralising antibodies that block fusion could be safer and more effective against a range of flavivirus infections. The majority of flaviviruses are transmitted to humans through the bite of a mosquito or tick. None of the factors identified for their association with flavivirus seroprevalence (age, gender and place of residence) were modifiable. Despite the potential roles of these factors in flavivirus transmission or its prevention, their associations with flavivirus seroprevalence were negligible. This and the findings from the current study suggest that flavivirus infection in this region occurs at an early age. The efficiency of this process for flaviviruses may be limited by the small surface area of viral membrane exposed in the context of the mature virion. Three seabird tick-borne flaviviruses are recognized. The epidemiological monitoring of this arbovirus is classically based on the number of notified cases of dengue and of recent flavivirus infection confirmed by accredited laboratories.
